Modern Cryptography

(stemandleafdiagram long-form post!)

~ 2900 words

As you may have guessed, I love cryptography and ciphers even though I still don’t know much about them. I think classical ciphers are super interesting stuff and I love breaking them but I realised I knew nothing cipher-y after the end of World War 2, so I sought to rectify that!

(This is SO long - I got quite carried away (I do apologise), and as I wanted to cover so much here there are some concepts I don’t explain very thoroughly, but there are so many resources online if you want to learn more! When explaining how different forms of encryption work, I will often use the names commonly used by other cryptographers in my examples. Alice and Bob are two people trying to communicate, while Eve (an eavesdropper) is trying to intercept their messages.)

Symmetric Encryption

The start of modern cryptography is not a definite thing (obviously so, as the “eras” of cryptography are just labels people use to refer to them generally) but I decided to start my timeline for modern cryptography in the 1960s, as during this time, research projects at the American company IBM (International Business Machines) led to the creation of a cipher called the Lucifer cipher. 

This cipher was one of the first block ciphers to be made. A block cipher is a cipher that operates on blocks of 128 bits at a time. This is in contrast to a stream cipher, which encrypts 1 bit of data at a time. (In a way, you could consider classical ciphers stream ciphers) If the plaintext (un-encrypted data) is smaller than 128, padding schemes will add random data to it to make it up to 128. Modes of operation define how large amounts of data are encrypted. For example, the blocks of data can be encoded separately, or maybe the encryption of one block is affected by the previous encoded block of data.

The Lucifer cipher underwent a lot of alterations, and eventually the National Bureau of Standards adopted this altered version of Lucifer as the Data Encryption Standard, or DES, in 1977. Some of the alterations made that led to DES were actually quite controversial! For example, the key size in Lucifer was 128 bits, but only 56 in DES, which worried people who thought it would have been easier to brute force as it was shorter. It’s actually rumoured that the NSA (National Security Agency) did this so that the DES wasn’t too strong for them to break. Another change they added was the inclusion of something called S-boxes, which are effective at protecting against a form of attack called differential cryptanalysis. What I found really cool was that its effectiveness wasn’t talked about until much after, which suggests that the NSA knew about differential cryptanalysis 13 years before this information went public!

The DES is no longer secure enough for modern use, and in 2001 was replaced by the AES, or the Advanced Encryption Standard, which is its direct successor and is still used today. The reason that AES is more secure than DES is that the algorithm itself is more complex, but more importantly it uses longer key lengths. Using keys that are 128, 192, or 256-bit long means that the encryption is much stronger than using the 56-bit DES.

Lucifer, DES, and AES are all symmetric ciphers as well as being block ciphers. This means that the key used to encrypt the plaintext is the same key that is used to decrypt the data. Only some block ciphers are known publicly. DES and AES are the most famous of the lot, but other ones such as IDEA, Twofish, and Serpent exist too. 

As a whole, encrypting with block ciphers is slower as the entire block must be captured to encrypt or decrypt, and if just 1 mistake is made the whole block can be altered. But, they are stronger than other ciphers. Each mode of operation also has its own pros and cons. If each block is encoded by itself then they can be encrypted in parallel (which is faster), but it’s prone to cryptoanalysis as two identical blocks of plaintext would produce two identical blocks of ciphertext, therefore revealing patterns. The other ways are much more complex and take more time to encrypt but are more secure. 

For symmetric encryption to be used, both parties need to agree on the same key for the message to be shared secretly, which is a massive problem. How can the key be transferred securely?

Key Exchange

A year before the implementation of DES, in 1976, another massive breakthrough was made. Researchers Whitfield Hellman and Martin Diffie created the Diffie-Hellman key exchange, which was a method to share encryption and decryption keys safely across an unsecured network. The way it works depends on one-way functions. Typically in maths, most functions are two-way, as using a function on a number is pretty easy to undo. However, Hellman and Diffie found out that while multiplying two prime numbers was very easy, factorising the product down to its primes again was excruciatingly difficult, and the difficulty only increases as the numbers get bigger.

Say Alice and Bob are trying to share a key using the Diffie-Hellman exchange. Firstly, both of them need to execute a function in the form G^a mod P. P must be prime, and G and P are shared publicly so Alice and Bob can agree on them. The numbers are massive (usually 2048 bits) to make it harder to brute force, and they are generated randomly. Alice and Bob each choose different numbers for a, and run their functions. They will get different answers and they share their answers with each other publicly. (This is the public key) Then, Alice and Bob run another function in the form G^a mod P, but G is set to the other person’s answer. The value of a and P stay the same, and Alice and Bob arrive at the same secret answer. The secret answer can then be used to encrypt the message! (This is the private key)

Now, let’s say Eve wanted to find out what the key was. She intercepts their messages, but even though she has the exact information Alice and Bob shared with each other, she doesn’t know what the secret key is unless she solved the original equation, making this key exchange very secure! Modular arithmetic (the mod P part of the equation) is notoriously hard to reverse. If 2048-bit numbers are used, then brute forcing it requires 2^2048 numbers.

Asymmetric Encryption

The Diffie-Hellman key exchange was huge - I mean, any technology created 50 years ago that’s still in use must be pretty good, but it really only shone for sharing keys, not for encryption. For example, the issue with sending communication such as emails using Diffie-Hellman was that both parties needed to be online for a key to be generated as information needs to be mutually shared in the process, so you couldn’t just send an email using it whenever you wanted, which was a shame. However, one particular thing it did lead to was the invention of asymmetric encryption.

In 1977, the idea of public key cryptography (also invented by Diffie) came to fruition in the form of RSA. Named after its creators (Ron Rivest, Adi Shamir, and Leonard Adleman), the RSA works by all users having a public key, which is accessible by everyone, so anyone wanting to send that user a message just needed to search for it. The sender encrypts the message with the recipient’s public key, and then when the recipient comes online they are able to decrypt it with their own private key that’s not shared with anyone. It also uses an one-way function like the Diffie-Hellman exchange, albeit a more complex one. RSA is still used today for things like sending messages or visiting secure websites, and the keys tend to be 2048 or 4096 bits long so that they are hard to break. 1024-bit RSA was disallowed in 2013.

Encrypting via public key and decrypting via private key is great for keeping sensitive information safe, but what if you encrypted with your private key and the message was decrypted with your public key? The purpose of this encryption is to prove the sender is who they say they are - if the public key can’t decrypt the message then either the wrong key was used or the message has been meddled with in transit. To keep the message secure the sender could encrypt with their private key and also the recipient’s public key so only they could decrypt and read it. If the message is particularly long, the digital signature can be applied to a hash of the original message, rather than the whole thing. The RSA was the first to have this dual functionality.

So, there we go - the two main encryption types used today: symmetric and asymmetric. Symmetric encryption is useful for large amounts of data in particular, while asymmetric is more secure, but is slower and requires more resources and therefore can be more expensive. In practice, many secure systems will use both symmetric and asymmetric ciphers. Although, the actual security of a message comes down to the length of the key used - the longer or more complex it is, the more secure the encryption is. As the number of bits increases, the total number of arrangements for these bits increases exponentially. The IBM website states that a 56-bit key could be brute forced in around 400 seconds, a 128-bit key would take 1.872 x10^37 years, while a 256-bit key would take 3.31 x10^56 years.

Going Quantum

It goes without mention as to how important modern cryptography is. These encryption methods are used to keep confidential information such as credit card details, messages, and passwords safe for users like you and me, but also maintains government security on a national level. It’s also vital for cryptocurrency and digital signatures (as mentioned before), as well as browsing secure websites.

A big threat to current cryptographic standards is the development of quantum computing, which are computers based on principles of quantum mechanics. I won’t go into detail on how quantum computers work, but using quantum mechanics they are able to do massive numbers of calculations simultaneously. Although quantum computers already exist, they aren’t powerful or capable enough to threaten our current encryption algorithms yet. But, researchers suggest that they could be able to within a decade. People could use a technique called “store now, decrypt later”, where they keep currently encrypted messages so that they can decrypt them when quantum computers are available. This could cause many problems in the future, particularly if they involve secrets on an international level.

Quantum mechanics can also be used in cryptography as well! Quantum cryptography, originally theorised in 1984 by Charles Bennett and Gilles Brassard, can be used to exchange keys even more securely than Diffie-Hellman, and is called QKD, or Quantum Key Distribution. The reason it’s so incredible is that data that’s secured using it is immune to traditional cryptographic attacks. Now, I’m no quantum physicist (or any type of physicist!) but I will try my best to explain how it works. It works by sending photons, which are light particles, from the sender (eg. Alice) to the receiver (eg. Bob). These photons are sent at different orientations and Bob can measure the photon’s polarisation when he gets them.

Let’s say that photons can be in a vertical, horizontal, or one of the two diagonal orientations. We can pass them through a polarised filter to find out what orientation they are in. The filters are also specifically oriented. A vertical filter would let the vertical photons through, block the horizontal ones, and let the diagonal ones in 50% of the time but at the cost of the ones that pass through being reoriented. Therefore, when a particular photon successfully passes through, it’s impossible to know whether it was originally diagonal or vertical. This is important as it means that it’s possible to detect if someone else has been eavesdropping as the polarisations would have been changed.

Bob can use two measurement bases to receive the photons Alice sent. One will capture vertical and horizontal orientations, and one will capture diagonal ones. Bob has no idea what orientation Alice used for each photon, so he switches between his bases randomly, and will get it wrong some of the time. This is fine, as Alice and Bob then compare to see which ones Bob got right, and the ones he correctly guessed are used as a key (each photon representing 1 bit). The key can then be used for other encryption methods, such as AES.

The reason this works is that if Eve wanted to pry, she has to guess which base to use as well when she intercepts the photons (so she will also make mistakes), but she has no way of checking whether her records are correct or not, unlike Bob. It’s impossible for her to obtain the key as well. What’s more, when she guesses wrong she will change the photon polarisation, so Alice and Bob know that she’s eavesdropping.

Quantum cryptography would have huge security benefits if implemented on a wide scale due to its ability to prevent eavesdroppers, and the fact that it would be resistant to quantum computers. However, it is still in development. One key drawback is the specific infrastructure that is needed, and fiber optic cables have a limited range. This means that the number of destinations the data could be sent to is limited, and the signal cannot be sent to more than 1 recipient at any time.

As well as quantum cryptography, the NIST (The National Institute of Standards and Technology) and other cryptographers are working on other cryptographic algorithms that would stay secure even in the face of quantum computers. Ideas include lattice-based cryptography, hash-based cryptography, and code-based cryptography among others but none of them are at a point where they can actually be implemented yet.

However, one new idea that isn’t post-quantum but is gaining traction is Elliptic Curve Cryptography. Elliptic curve cryptography (ECC) is a form of asymmetric encryption that uses different points on an elliptic curve graph to generate keys in a more efficient manner than traditional methods. It creates shorter encryption keys, which means that less resources are needed while making the keys harder to break simultaneously. Improving the security of current systems just involves lengthening the keys, which slows down the encryption/decryption process, so the fact that ECC doesn’t need to do this gives it a big advantage. It is already used by the US government, iMessage, and Bitcoin, among others. 

Sidenotes

With the maths of these encryption methods being so strong, one key vulnerability is the people that utilise these methods, which is no surprise. Side channel attacks are a way to break cryptography by using information physically leaked from it. One attack, called a TEMPEST attack, is a technique that can pick up electromagnetic transmissions from a device as far as 300m away. These are often done by the FBI, but honestly can be done quite easily by some nerd who has some money to spare and can sit in a car outside your window. By monitoring the radiation emitted from your computer screen, the attacker can spy on you and your data. Another thing that can be monitored is your power consumption. Cryptography is energy intensive, and this attack has been able to recover RSA private keys in testing. Other forms of attacks include measuring amount of time required to encrypt data, which can perhaps be used to find factors or exponents. To combat this, encryption methods can add timing noise as a countermeasure. Or, an attacker can listen to someone type to find out their passwords, but to distinguish different key presses a sophisticated machine learning model is needed. Side channel attacks have actually been around for ages but its use has been severely limited in that the attacker needs to be physically close to the victim. They could get easier with time, however, as smartphones and drones can act as microphones remotely.

Another cool thing I haven’t covered yet are hash functions, which can take in an input and map it to a string of characters that’s random but unique to the original data. The output is called a hash digest or hash value. A good hash function will mean that no two different inputs will have the same hash value, and all outputs are the same length, making it hard to guess original text length. It’s vital for digital signatures and storing passwords securely.

Finally, if anyone managed to get to the end, then thank you! I really love cryptography and I find it astounding that we’ve been able to develop it into such a complex yet intrinsic part of daily life. Honestly, I had so much fun researching for this post! Encryption and cybersecurity and the future of computing is so interesting and I’m really glad I decided to write this :)

Final final note you should totally go and read the Code Book by Simon Singh! Trust me trust me it’s so good...

!/bin/bash

BACKUP_DIR="/backup" DATA_DIR="/important_data/" ENCRYPTED_BACKUP="$BACKUP_DIR/encrypted_backup_$(date +%F).gpg"

tar -czf $BACKUP_DIR/backup_$(date +%F).tar.gz $DATA_DIR gpg --symmetric --cipher-algo AES256 --output $ENCRYPTED_BACKUP $BACKUP_DIR/backup_$(date +%F).tar.gz rm -f $BACKUP_DIR/backup_$(date +%F).tar.gz echo "Encrypted backup completed."

To refine encryption-related code, consider the following improvements:

Use Stronger Algorithms: Implement AES256 instead of AES128 for better encryption strength.

Add Error Handling: Ensure that the encryption process handles errors, such as failed encryption or permission issues.

Secure Storage of Keys: Use a secure method to store encryption keys (e.g., environment variables or hardware security modules).

Refined Script Example:

!/bin/bash

Encrypt sensitive data with AES256 and store encrypted backup securely

BACKUP_DIR="/backup" ENCRYPTED_BACKUP="/backup/encrypted_backup_$(date +%F).gpg" DATA_DIR="/important_data/"

Perform backup of important files

tar -czf $BACKUP_DIR/backup_$(date +%F).tar.gz $DATA_DIR

Encrypt the backup with AES256

gpg --batch --yes --symmetric --cipher-algo AES256 --output $ENCRYPTED_BACKUP $BACKUP_DIR/backup_$(date +%F).tar.gz

Remove the unencrypted backup file

rm -f $BACKUP_DIR/backup_$(date +%F).tar.gz echo "Backup and encryption completed securely."

This script enhances security by using AES256 and ensures encrypted files are properly handled.

To proceed with creating scripts for securing water companies' networks, we would outline some basic examples and operational strategies that could be implemented. Here’s a breakdown of each element:

Monitoring and Intrusion Detection

These scripts would monitor traffic and detect any suspicious activity on the network.

Example Script: Network Traffic Monitoring

!/bin/bash

Monitor network traffic and detect anomalies

LOGFILE="/var/log/network_traffic.log" ALERT_FILE="/var/log/alerts.log"

Use 'netstat' to monitor active network connections

netstat -an > $LOGFILE

Check for unusual activity, such as unexpected IP addresses

grep "192.168." $LOGFILE | grep -v "127.0.0.1" > $ALERT_FILE if [ -s $ALERT_FILE ]; then echo "Unusual activity detected!" | mail -s "Security Alert: Network Anomaly Detected" admin@watercompany.com fi

This script monitors network traffic using netstat, checks for connections from suspicious IP addresses, and sends an alert if any are found.

Intrusion Prevention (Automated Response)

This script would automatically take action to block malicious activity upon detection.

Example Script: IP Blocking on Intrusion Detection

!/bin/bash

Block suspicious IP addresses detected during intrusion attempts

SUSPICIOUS_IPS=$(grep "FAILED LOGIN" /var/log/auth.log | awk '{print $NF}' | sort | uniq)

for ip in $SUSPICIOUS_IPS; do iptables -A INPUT -s $ip -j DROP echo "$ip has been blocked due to multiple failed login attempts" >> /var/log/security_block.log done

This script automatically blocks IP addresses with failed login attempts, adding a layer of protection by preventing brute-force attacks.

Security Updates and Patch Management

Automated patch management ensures that all security vulnerabilities are addressed as soon as updates are available.

Example Script: Automatic Updates

!/bin/bash

Update system packages and apply security patches

echo "Updating system packages…" apt-get update -y apt-get upgrade -y apt-get dist-upgrade -y

Apply only security updates

apt-get install unattended-upgrades dpkg-reconfigure -plow unattended-upgrades

This script ensures that the system receives the latest security patches automatically, which is essential for keeping critical infrastructure secure.

Data Encryption and Backup

Regular backups and ensuring sensitive data is encrypted are vital.

Example Script: Data Encryption and Backup

!/bin/bash

Encrypt sensitive data and create backups

BACKUP_DIR="/backup" ENCRYPTED_BACKUP="/backup/encrypted_backup.gpg"

Perform backup of important files

tar -czf $BACKUP_DIR/backup_$(date +%F).tar.gz /important_data/

Encrypt the backup

gpg --symmetric --cipher-algo AES256 $BACKUP_DIR/backup_$(date +%F).tar.gz

Remove the unencrypted backup file after encryption

rm -f $BACKUP_DIR/backup_$(date +%F).tar.gz echo "Backup and encryption completed."

This script automates backups of sensitive data and encrypts it using gpg with AES256 encryption, ensuring that even if data is accessed illegally, it cannot be read without the encryption key.

Access Control

Strong access control is necessary to ensure that only authorized personnel can access critical systems.

Example Script: Access Control with Multi-Factor Authentication (MFA)

!/bin/bash

Ensure all users have MFA enabled for critical systems

Check if MFA is enabled on SSH login

if ! grep -q "auth required pam_google_authenticator.so" /etc/pam.d/sshd; then echo "MFA is not enabled on SSH. Enabling MFA…" echo "auth required pam_google_authenticator.so" >> /etc/pam.d/sshd service sshd restart else echo "MFA is already enabled on SSH." fi

This script checks if multi-factor authentication (MFA) is enabled on SSH logins, and if not, it enables it, ensuring an additional layer of security.

Security Audits

Regular audits help identify vulnerabilities and ensure the system is secure.

Example Script: Automated Security Audit

!/bin/bash

Run a security audit to check for common vulnerabilities

Check for open ports

echo "Checking for open ports…" nmap -p 1-65535 localhost > /var/log/open_ports.log

Check for outdated software

echo "Checking for outdated software…" apt list --upgradable > /var/log/outdated_software.log

Check file permissions for sensitive files

echo "Checking file permissions…" find /etc /var /usr -type f -name "*.conf" -exec ls -l {} \; > /var/log/file_permissions.log

Send the audit report to the administrator

mail -s "Security Audit Report" admin@watercompany.com < /var/log/security_audit_report.log

This script performs a security audit, checking for open ports, outdated software, and sensitive file permission issues, then sends a report to the administrator.

Conclusion

These scripts are designed to help secure the water companies' networks by automating essential security functions like monitoring, response to threats, patching, encryption, and access control. It’s important that these scripts be customized to the specific needs of each company, taking into account their existing systems, infrastructure, and any unique security concerns they may face. Additionally, regular updates to these scripts will be necessary as new vulnerabilities and threats emerge.

For a basic firewall script that blocks unauthorized access and monitors network traffic, here's an example:

!/bin/bash

Define allowed IPs (replace with actual allowed IP addresses)

ALLOWED_IPS=("192.168.1.1" "192.168.1.2")

Block all incoming connections by default

iptables -P INPUT DROP iptables -P FORWARD DROP iptables -P OUTPUT ACCEPT

Allow traffic from specified IPs

for ip in "${ALLOWED_IPS[@]}"; do iptables -A INPUT -s $ip -j ACCEPT done

Log and monitor incoming traffic

iptables -A INPUT -j LOG --log-prefix "Firewall Log: " --log-level 4

This script sets a default block on incoming connections, allows traffic from specific IP addresses, and logs all traffic for monitoring.

chinhands. PLEASE tell me about symmetric encryption

Anon!! <3 I'd love to, but I'm gonna do it under a cut because this is a nerdy ramble that has nothing to do with the theme of this blog. I want to spare the people who solely come here for the vroom vroom men from this explanation. Also, I found out apparently in English it's "symmetric key encryption" and some of them are called ciphers??? but same difference.

Okay, so. You have a super secret message that you want nobody else to know about. Like, for example, "RPF is fine."

If you want to send your friend this message, it could get intercepted along the way, and you do not want to let anyone except that friend know that you are an rpf supporter. To achieve this, you have to encrypt your super secret message, send it to your friend, and they decrypt your message so they can read it. Anyone who intercepts that message will only be able to read gibberish.

A key forms the basis for this mechanism. With symmetric encryption, you use THE SAME key for encrypting the message & for decrypting the message. So, you need to give your friend information on what the key is. Only then can they decrypt your super secret message later on.

One of the first methods that got used is the Caesar Cipher, named after that Roman Guy, Julius Caesar, you might know from history or that one Shakespeare play.

The key in this case is moving the letters of the alphabet a certain number of times to encrypt something. Using the example from earlier, you and your friend love Lando Norris, so you decide to use the key 4 for your encryption. Every letter of your message then gets moved 4 letters further for encryption and your friend moves it 4 letters back to decrypt it.

So "RPF IS FINE" becomes "VTJ MW JMRI" (i hope i did it correctly lmao). But you see, that anyone reading this message wouldn't be able to know what it's about. At first glance.

Buuut, this method isn't exactly safe. There are only this many keys you can use. A clever person with enough time can just try ALL the keys and eventually find the one that works (called: brute-forcing), decrypt your super secret message, and find out about your avid love for rpf.

How do you prevent people from finding out the keys? Use more of them.

In comes Alberti, who got the genius idea of using DIFFERENT secret alphabets for encryption and also arrange them on a cool movable disk called the Formula if wikipedia is to be believed (the ... Formula 1 perhaps?)

Wooow, look at it! Isn't it nifty, as Russell George might probably say?

You have your normal alphabet on the inner ring and a secret alphabet on the outer one. If you move the outer ring, the letter now suddenly corresponds to another one and you've changed your key! The letter A might be a C in the first alphabet but a letter H in the second one. You can then tell your friend how often you change the key and by how much and they can decrypt is. This is much harder to crack, which is what we want.

A more famous one of those so called "polyalphabetic cyphers" (cause you assign each plaintext letter more than 1 substitute letter) is the Vigenère cipher. It was considered unbreakable for 300 years!!! That's quite some time.

It's kinda but not really like the Caesar cipher. Instead of a single number key, you have a whole KEYWORD or KEYPHRASE. And each letter of the word/phrase corresponds to how much you'll move the letter of your original message forward in the alphabet, with A =0, B = 1, C = 2, ...

Using our example from earlier: You also really like Oscar, so you and your friend decide to use OSCAR as the Keyword and you send them the message from earlier. "RPF IS FINE" then becomes "FHH IJ TAPE" and someone who reads it thinks that you might want tape? Sure?

The other part of the coin to encryption is asymmetric key encryption. Because sometimes you can't tell your friend your super secret key to encrypt your super secret message, so you need to find an algorithm that uses key1 to encrypt the message and ANOTHER, SECOND, DIFFERENT key to decrypt it. But this goes beyond the acceptable post length, probably.

This got ... quite long and I haven't even touched on The Enigma (sending encrypted messages during the war) or on how some symmetric key encryption is still used today, like in the last part of the protocol you use to be on this website! HTTPS!

I hope at least 1 person read this and goodnight <3

The Future of Data Security: Advanced Encryption Algorithms

Every time we share a file, store data encryprion in our cloud storage, or collaborate online, we fear exposing information to some unknown threats. With the ongoing data breaches in the digital landscape, securing data has become the call of the hour. 

Traditional encryption methods that used to be reliable are now struggling to keep pace with today’s threats. They weren’t designed to handle the rapid-fire attacks, massive data demands and other looming challenges. 

However, to stay ahead of the game, there are advanced encryption algorithms that are robust and future-ready. Protect sensitive data in this ever-evolving digital environment.

This blog will shed light on these advanced encryption algorithms and discuss how they can protect our information. 

What is Encryption?

At the very core of security, encryption is like locking your data into a digital safe. Only people with the key can open it. But the safes aren’t all built alike. In encryption, once you decide to secure the data, there are encryption methods, which are broadly categorized into two categories, namely – symmetric and asymmetric.

Symmetric encryption uses one key for both encryption and decryption, and in such a manner that it’s fast enough to encrypt large amounts of data, internal file storage, or a backup system. The difficulty, though, is in safely transmitting the key. If someone intercepts it, your data is at risk.

Used Algorithms include – the Advanced Encryption Standard (AES), the older Data Encryption Standard (DES), and its successor, the Triple DES (3DES) algorithm.

Asymmetric encryption operates using a pair of keys one public for encrypting the data and a corresponding private key used to decrypt it.

This encryption is slower compared to symmetric encryption but provides a safer way of exchanging information that does not involve sharing sensitive keys. WhatsApp, online transactions, and digital signatures are some examples of how this type of Advanced Encryption Standard is used. 

Used Algorithms – RSA (Rivest-Shamir-Adleman), Diffie-Hellman. 

Common Algorithms for Encryption

Choosing the correct encryption algorithm is no longer a technical decision; it’s now a matter of safety. Let us now look at some of the most extensively implemented encryption mechanisms that are building blocks today in data security.

1. AES (Advanced Encryption Standard)         

The Advanced Encryption Standard (AES) is one of the most trusted symmetric block cipher methods used to secure data. It encrypts information in fixed blocks of 128 bits and supports key lengths of 128, 192, or 256 bits. Among these, AES-256 is recognized for its enhanced security and is officially approved by U.S. government agencies for protecting classified information.

Fast and highly safe, this is the best choice for either hardware or software implementations. Whatever the case, securing data in the cloud or even for internal systems, AES will always prove to be the most convenient, scalable, and reliable solution so governments, banks, and security-conscious corporations use it.

2. Triple DES (3DES)

Triple DES was made to improve the original DES (Data Encryption Standard), which was becoming vulnerable due to its limited key size. 3DES increases data security by using DES three times on a single block. While it was a reliable encryption algorithm at its time, it’s now considered obsolete and is being pushed aside by newer-generation algorithms like AES. Nevertheless, it is good to know that many legacy systems still use that.

3. RSA (Rivest–Shamir–Adleman)

The RSA algorithm was among the first widely used asymmetric encryption techniques. It generates two keys, one private and one public. For transferring safe data across open networks like the Internet, this makes it ideal. Emails, SSL certificates, and digital signatures are all encrypted using RSA. It is, however, slower than symmetric methods and thus cannot be used in encrypting enormous volumes of data.

What makes an algorithm advanced?

For an algorithm to be considered advanced, it must be resistant to contemporary attack methods such as cryptographic analysis and side-channel attacks. It should also be scalable. Most importantly, it needs to be future-proof or at least adaptable to the fast-changing landscape of cybersecurity. 

In this case, the Advanced Encryption Standard (AES) is a prime example, particularly the variant of AES-256. This version involves 14 rounds of encryption, where the data undergoes a series of shifts, substitutions, mixing, and key additions that make it quite impossible to decode without the exact key. 

Preparing for the Future: Securing Data with Advanced Encryption Algorithms

The repercussions of inadequate data security can be severe, affecting everything from customer trust to regulatory compliance. That’s why innovative organizations are investing in advanced encryption algorithms now to tackle the challenges of tomorrow. 

Platforms like eShare.ai are leading the charge in this transformation. By adopting cutting-edge encryption standards 

and facilitating secure file collaboration, this platform makes sure that sensitive information remains safe, whether it’s being stored, shared, or accessed by different teams. That’s because the future of data security isn’t just about stronger defenses; it’s about smarter, scalable, and proactive measures.

Lipkin Meshkov Glick Model on Neutral Atom Quantum Computer

Lipkin Meshkov Glick Model

Variational-quantum-eigensolver algorithm for neutral atom quantum computer Lipkin-Meshkov-Glick model simulation. Spin systems' ground-state energy is measured up to 15 spins. Encoding strategies include an individual spin encoding where each spin is represented by one qubit and an efficient Grey code encoding that takes a logarithm of spins. This more efficient encoding and zero-noise extrapolation enhance simulated energy accuracy to perfect answers.

A fundamental theoretical framework for analysing quantum systems having a finite number of two-level atomic quantum states is Lipkin-Meshkov-Glick (LMG). The 1960s-founded organisation studied nuclear giant monopoles and many-body physics computer simulations. It is now a key test location for many-body physics approximation methods. Because it is non-trivial but precisely solved, it is ideal for computational confirmation.

In Bose-Einstein condensates, quantum correlations, and statistical mechanics with spin relationships, the LMG model works. It is increasingly used in quantum thermodynamics to build and test thermodynamic cycles, notably for quantum phase transitions. Comparative studies of quantum Otto and Carnot cycle performance metrics have used it.

Physics: Benchmarking Heat Engine and Quantum Computing Improvements with a Common Theoretical Model

Recent scientific advances are illuminating quantum technologies' potential using two Lipkin-Meshkov-Glick model studies. An LMG model-based study evaluates neutral atom quantum computers, while another examines the quantum Otto machine. These simultaneous discoveries show how swiftly quantum thermodynamics and computing power are advancing.

Maxing Out Quantum Heat Engine Efficiency

The quantum Otto machine's quantum heat correlations, performance, and efficiency were studied in Optical and Quantum Electronics using the discrete sides of the LMG model as its working medium. Quantum heat engines (QHEs) may produce a “paradigm shift” in technology and outperform thermal machines. Otto engines are popular because they clearly separate heat and work exchange in their phases.

The LMG model was examined for symmetric cross-interaction and magnetic field spin interactions. Key study findings include:

Symmetrical heat correlations were always found around the coupling of the symmetric cross-interaction in anisotropic XY, Ising, or mixed ferromagnetism models.

Although the maximum boundaries varied, two or three sides of the mixed ferromagnetic working substance functioned symmetrically.

The two-sided mixed ferromagnetism model became more efficient as the exchange parameter climbed.

The discovery that a three-sided spin interaction can accurately manage the system's anisotropy parameter led to the QHE or quantum refrigerator. Mixed ferromagnetic situations were more efficient and anisotropic than Ising. An optimal Carnot efficiency can be achieved with fewer “atoms” (two-side spin interaction) in a QHE, but it decreases with more atoms.

When the external magnetic field was stronger than the exchange coupling, symmetric cross-interaction coupling was needed to maintain heat correlations and avoid adiabatic process disruptions.

The study also examined certain operations:

The two-side mixed ferromagnetism LMG model developed a QHE with positive work done and heat absorbed and negative heat released under low external magnetic field coupling and particular exchange coupling. The system ended thermodynamically when the symmetric cross-interaction increased beyond a certain range.

The device can operate as a QR for the two-side anisotropic XY system at zero symmetric cross-interaction (work done and heat emitted negative, heat absorbed positive) and a QHE when coupling is enhanced. Increased exchange coupling and external magnetic field coupling can make the two-side anisotropic XY system a heater (negative heat absorbed).

In the three-side LMG model, a QHE was obtained by setting (\gamma) to -1, whereas a QR was obtained by setting (\gamma) to 0 (Ising model) or 1 (anisotropic XY model). Increased exchange coupling parameter may result in an accelerator operation around zero symmetric cross-interaction in these latter cases. In general, two sides had higher work output limits than three sides.

This study suggests that customised quantum matter like the LMG model can work as a working medium in quantum thermodynamic cycles, possibly producing more work than traditional engines, when employed between comparable thermal reservoirs.

Benchmarking Quantum Computers with LMG

A neutral atom quantum computer was used to simulate the LMG model using the Variational Quantum Eigensolver (VQE) algorithm in another work. The LMG model is ideal for testing new and old quantum computers since it is solvable. It achieves the same goal for quantum machines 60 years after being applied to classical systems in the 1960s.

Besides technological breakthroughs, the research team examined the ground-state energy of spin systems with up to 15 spins:

We directly contrasted a very successful Grey code encoding that requires a number of qubits scaling logarithmically with spins and a spin encoding (one spin per qubit). With appropriate encoding, three qubits may replicate 15 spins.

Zero-noise extrapolation (ZNE) improved performance for the researchers. ZNE reduces gate errors, improving simulated energy accuracy beyond intrinsic physical gate fidelities. They used SIIM and FIIM ZNE for this.

Neutral atom processor breakthroughs included moving Caesium (Cs) atoms for dynamic qubit connection and fast optical control beam scanning. Executing quantum algorithms with these qualities increased two-qubit gate fidelity to 0.971(1).

ZNE agreed well with theoretical ground-state energies for up to seven spins and roughly 5% for nine spins, but larger systems still have concerns. VQE convergence was prone to entrapment in local energy minima, especially for the 15-spin system, even in noise-free simulations. This advises using more advanced adaptive optimisation methods and expanding the search to more beginning circumstances.

This paper shows how neutral atom quantum computers can simulate complex many-body spin models, highlighting the importance of good encoding and noise reduction approaches in quantum computation. The challenges of larger systems underscore the need for quantum error correction and robust optimisation advances.

The Impact of Quantum Computing on the Future of Cyber Security

For decades, cybersecurity has relied on the seemingly impenetrable mathematical fortresses of classical cryptography. Our digital world, from secure online banking to encrypted communications, is built on the assumption that breaking these codes would take even the most powerful supercomputers an impossibly long time – trillions of years, in some cases.

But a seismic shift is on the horizon, one that promises to dismantle these fortresses with frightening speed: quantum computing. While still in its early stages, the rapid advancements in quantum technology signal a fundamental re-evaluation of how we protect our most sensitive information. This isn't just an upgrade; it's a revolution that will impact every facet of cybersecurity.

The Looming Threat: What Quantum Computers Can Break

The primary concern revolves around Shor's Algorithm. Developed by Peter Shor, this quantum algorithm can efficiently factor large numbers and solve discrete logarithm problems – the very mathematical bedrock upon which widely used public-key encryption standards like RSA and Elliptic Curve Cryptography (ECC) are built.

Imagine this: the encryption securing your online transactions, your VPN connection, your digital signatures, and even the confidentiality of critical government data could theoretically be cracked in mere seconds or minutes by a sufficiently powerful quantum computer. This isn't a distant threat; it's a future that cybersecurity professionals are actively preparing for.

Another quantum algorithm, Grover's Algorithm, while not directly breaking encryption, can significantly speed up brute-force attacks on symmetric-key algorithms like AES (Advanced Encryption Standard). This means that to maintain the same level of security, we'll need to double the key lengths of these algorithms.

The implications are profound, leading to fears of a "quantum apocalypse" where much of today's encrypted data becomes vulnerable. This also gives rise to "harvest now, decrypt later" attacks, where malicious actors collect encrypted data today, knowing they can decrypt it once quantum capabilities become available.

The Silver Lining: Quantum Computing as a Shield

It's not all doom and gloom. The relationship between quantum computing and cybersecurity is a double-edged sword. Just as quantum computing poses threats, it also offers unprecedented opportunities to build more robust and future-proof security solutions:

Post-Quantum Cryptography (PQC): This is the most crucial line of defense. PQC involves developing new cryptographic algorithms that are resistant to attacks from both classical and quantum computers. Organizations like the National Institute of Standards and Technology (NIST) are actively standardizing these new algorithms, which are based on different mathematical problems that are believed to be hard for even quantum computers to solve (e.g., lattice-based, hash-based, and code-based cryptography). The transition to PQC will be a monumental effort, requiring upgrades across all digital infrastructure.

Quantum Key Distribution (QKD): This technology leverages the fundamental laws of quantum mechanics to enable two parties to establish a shared encryption key with provable security. Any attempt by an eavesdropper to intercept the key would inevitably alter its quantum state, immediately alerting the communicating parties. While QKD offers theoretical "unhackable" communication, its practical implementation faces challenges related to distance and infrastructure.

Enhanced Threat Detection: The immense processing power of quantum computers could revolutionize threat detection and response. Quantum algorithms might be able to analyze vast datasets of network traffic and system logs at unprecedented speeds, identifying anomalies and sophisticated attack patterns far more efficiently than current AI/ML systems. This could lead to real-time, proactive defense capabilities.

The Road Ahead: Preparation is Key

While a fully fault-tolerant, universal quantum computer capable of breaking current encryption may still be years, or even a decade or two, away, the cybersecurity community is not waiting. The timeline for the "quantum safe" transition is long, and history shows that cryptographic migrations can take well over a decade.

Organizations, governments, and individuals must start preparing now:

Inventory Cryptographic Assets: Identify all systems, applications, and data that rely on current public-key cryptography.

Assess Quantum Risk: Determine the level of risk quantum attacks pose to your critical data and infrastructure.

Develop a PQC Migration Roadmap: Plan for the phased adoption of quantum-resistant algorithms, considering hybrid approaches that combine classical and PQC methods during the transition.

Invest in Crypto Agility: Build systems that can easily swap out cryptographic algorithms as new standards emerge and threats evolve.

Stay Informed: Keep abreast of the latest developments in quantum computing and post-quantum cryptography research.

The quantum era will undoubtedly redefine cybersecurity. While it brings significant challenges to our existing security paradigms, it also ushers in an exciting era of innovation, promising a future where our digital defenses are stronger and more resilient than ever before. The time to prepare for this quantum reckoning is now.

How Parametric Design is Reshaping Modern Architecture

Parametric design has emerged as a game-changer in the world of architecture. It’s helping top firms redefine skylines, create adaptive spaces, and solve complex design challenges. From awe-inspiring buildings to environmentally responsive interiors, parametric design is shaping the future of how we live, work, and connect with spaces.

Why is it so relevant today? Advancements in technology, including AI and computational tools, combined with an urgency to meet sustainability goals, are driving its rapid adoption. Whether you’re an architect, a design student, or a tech enthusiast, this guide will walk you through the fundamentals, benefits, and potential of parametric design.

What is Parametric Design? 

Parametric design is an algorithmic approach to architecture that uses parameters, data, and rules to generate architectural forms. Parameters such as environmental conditions, material performance, and spatial needs are input into computational systems, which generate forms that adapt to these constraints.

How does it differ from traditional design processes? Traditional methods often follow a linear approach where ideas are sketched and refined. Parametric design, however, uses dynamic systems where forms evolve in real-time, influenced by data and algorithms. This approach enables innovative, fluid, and optimized architecture that wasn’t feasible with traditional methods.

Key Features of Parametric Architecture 

1. Complex, Organic Forms 

Traditional architecture focused on linear, often symmetrical designs. Parametric design, by contrast, creates fluid, organic shapes such as curved facades and free-flowing structures. Think of the Heydar Aliyev Center in Azerbaijan, designed by Zaha Hadid. Its sweeping, wave-like surfaces are a hallmark of parametric innovation. 

2. Responsive and Adaptive Structures 

Parametric design allows buildings to respond to contextual factors such as climate, wind, and sunlight. For instance, a structure can be designed to block excessive heat while allowing natural light to flood interior spaces. This creates not only visually stunning designs but also energy-efficient ones. 

3. Data-Driven Decision Making 

Every parameter in the computational modeling process represents data. This allows architects to simulate how their structures perform under real-world conditions, enabling precise adjustments before construction begins. 

4. Optimized Material Use and Efficiency 

Parametric tools are not just about aesthetics; they help save materials and costs. By optimizing structural designs, architects can reduce waste while ensuring the building’s integrity.

With global movements toward carbon neutrality, parametric design plays a crucial role in building energy-efficient structures. Achieving these goals requires innovative design approaches that maximize performance while minimizing environmental impact. 

2. AI and Computational Tools 

AI integrations and computational tools such as Grasshopper and Rhino make parametric methods practical and cost-efficient. These tools allow architects to design complex forms that are no longer prohibitively expensive or time-consuming. 

3. Early Performance Simulations 

Decisions based on sunlight orientation, wind paths, and energy insights begin during the earliest conceptual phases, allowing architects to design smarter and more responsive buildings. 

Iconic Examples of Parametric Architecture 

Heydar Aliyev Center - Azerbaijan 

Designed by Zaha Hadid, this structure features flowing curves and seamless surfaces, encapsulating the possibilities of parametric design. 

The Vessel, NYC 

A striking honeycomb-like structure in Hudson Yards, The Vessel offers a unique combination of functionality and artful geometry. 

Galaxy SOHO, Beijing 

Blending organic forms with urban dynamism, this structure by Zaha Hadid integrates parametric ideas seamlessly into a commercial landscape. 

The Louvre Abu Dhabi 

Its 'floating dome' allows intricate play of sunlight and shadow, demonstrating how parametric solutions create both aesthetic appeal and functional ingenuity. 

Indian Examples 

Closer to home, the Infosys Pune Campus highlights thoughtful use of parametric façades, and Ahmedabad Riverfront demonstrates how these principles enhance public spaces. 

The Role of Technology in Parametric Design 

Key Tools 

Rhino/Grasshopper: Popular tools for computational design that allow architects to craft intricate patterns and forms. 

Dynamo: A visual coding tool often integrated with Revit for generative design functionality. 

AI Plug-ins: Emerging tools such as Finch and Spacemaker use AI to predict optimal layouts and energy outputs. 

Real-Time Data Integration 

Parametric tools enable buildings to respond in real-time to environmental changes, enhancing their longevity and adaptability. 

Impact on Urban Design and Interiors 

Public Spaces 

Parametric methodology is enabling urban designers to craft interactive, efficient public spaces. By modeling movement patterns, environmental impacts, and social factors, spaces can cater directly to community needs. 

Modular Furniture and Smart Homes 

Parametric concepts are moving into interiors too. Designers use computational tools to create modular furniture and responsive designs that adapt to lifestyle changes. Think of furnishings that rearrange themselves based on available natural light or room usage! 

Challenges and Future Potential 

Challenges 

Learning Curve: Architects need to upskill in computational tools, which can be intimidating for some. 

Cost: While costs are dropping, applying parametric solutions can still strain budgets, especially for smaller firms. 

Client Acceptance: Some clients may hesitate to adopt parametric methods due to concerns over reliability or aesthetics. 

Future Potential 

AI Integration: AI will push parametric design further into generative design, predicting user needs before they arise. 

Robotics: From robotic assembly of parametric facades to material innovations, the future is brimming with possibilities. 

Sustainable Innovation: New materials and design strategies will combine parametric design with zero-waste goals. 

Widespread Adoption: With tools becoming more user-friendly, parametric design will likely grow from an innovation into a standard. 

Unlock Your Architectural Potential
