#Asymmetric-key cryptography

[govindhtech]

Cryptography’s three primary categories

Cryptography, from the Greek words meaning “hidden writing,” encrypts sent data so only the intended recipient can read it. Applications for cryptography are numerous. Cryptography is essential to our digital world and protects sensitive data from hackers and other cybercriminals, from WhatsApp’s end-to-end message authentication to legal form digital signatures to cryptocurrency mining’s CPU-draining ciphers.

One of the first cryptologists was Julius Caesar. Modern cryptosystems are more advanced yet work similarly. Most cryptosystems start with plaintext, which is encrypted into ciphertext using one or more encryption keys. The recipient receives this ciphertext. If the ciphertext is intercepted and the encryption algorithm is strong, unauthorized eavesdroppers cannot break the code. The targeted receiver can simply decipher the text with the correct decryption key.

Let’s start with robust cryptography frameworks’ key features:

Confidentiality: Only the intended recipient can access encrypted information.

Integrity: Encrypted data cannot be altered in storage or transit between sender and receiver without detection.

Non-repudiation: Encrypted information cannot be denied transmission.

Authentication: Sender, receiver, and information origin and destination are verified.

Key management: Data encryption and decryption keys (and related duties like key length, distribution, generation, rotation, etc.) are secure.

Three encryption types

Hybrid systems like SSL exist, although most encryption methods are symmetric, asymmetric, or hash functions.

Key symmetric cryptography

Symmetric key encryption, also known as private key cryptography, secret key cryptography, or single key encryption, employs one key for encryption and decryption. These systems need users to share a private key. Private keys can be shared by a private courier, secured line, or Diffie-Hellman key agreement.

Two types of symmetric key algorithms:

Block cipher: The method works on a fixed-size data block. If the block size is 8, eight bytes of plaintext are encrypted. Encrypt/decrypt interfaces usually call the low-level cipher function repeatedly for data longer than the block size.

Stream cipher: Stream ciphers convert one bit (or byte) at a time. A stream cipher creates a keystream from a key. The produced keystream is XORed with plaintext.

Symmetrical cryptography examples:

DES: IBM developed the Data Encryption Standard (DES) in the early 1970s. While it is vulnerable to brute force assaults, its architecture remains relevant in modern cryptography. 

Triple DES: By 1999, computing advances made DES unsecure, however the DES cryptosystem built on the original DES basis provides protection that modern machines cannot break.

Blowfish: Bruce Schneer’s 1993 fast, free, public block cipher.

AES: The only publicly available encryption certified by the U.S. National Security Agency for top secret material is AES.

Asymmetric-key cryptography

One secret and one public key are used in asymmetric encryption. This is why these algorithms are called public key algorithms. Although one key is publicly available, only the intended recipient’s private key may decrypt a message, making public key cryptography more secure than symmetric encryption.

Examples of asymmetrical cryptography:

RSA: Founded in 1977 by Rivest, Shamier, and Adleman, the RSA algorithm is one of the oldest public key cryptosystems for secure data transfer.

ECC: ECC is a sophisticated kind of asymmetric encryption that uses elliptic curve algebraic structures to create very strong cryptographic keys.

One-way hash

Cryptographic hash algorithms convert variable-length input strings into fixed-length digests. The input is plaintext, and the output hash is cipher. Good hash functions for practical applications satisfy the following:

Collision-resistant: A new hash is generated anytime any data is updated, ensuring data integrity.

One-way: The function is irreversible. Thus, a digest cannot be traced back to its source, assuring data security.

Because hash algorithms directly encrypt data without keys, they create powerful cryptosystems. Plaintext is its own key.

Consider the security risk of a bank password database. Anyone with bank computer access, authorized or illegal, may see every password. To protect data, banks and other companies encrypt passwords into a hash value and save only that value in their database. Without the password, the hash value cannot be broken.

Future of cryptography

A quantum cryptography

Technological advances and more complex cyberattacks drive cryptography to evolve. Quantum cryptography, or quantum encryption, uses quantum physics’ natural and immutable laws to securely encrypt and transfer data for cybersecurity. Quantum encryption, albeit still developing, could be unhackable and more secure than earlier cryptographic systems.

Post-quantum crypto

Post-quantum cryptographic methods use mathematical cryptography to generate quantum computer-proof encryption, unlike quantum cryptography, which uses natural rules of physics. Quantum computing, a fast-growing discipline of computer science, might exponentially enhance processing power, dwarfing even the fastest super computers. Although theoretical, prototypes suggest that quantum computers might breach even the most secure public key cryptography schemes in 10 to 50 years.

NIST states that post-quantum cryptography (PQC) aims to “develop cryptographic systems that are secure against both quantum and classical computers, and [that] can interoperate with existing communications protocols and networks.”

The six main quantum-safe cryptography fields are:

Lattice-based crypto

Multivariate crypto

Cryptography using hashes

Code-based cryptography

Cryptography using isogeny

Key symmetry quantum resistance

The dawn of asymmetric key encryption via Phil Zimmermann's "Pretty Good Privacy" software.

In 1991, Phil Zimmermann, a software engineer and privacy advocate, released Pretty Good Privacy (PGP), a groundbreaking encryption software that provided individuals with the means to secure their digital communications. The creation and distribution of PGP marked a pivotal moment in the field of cryptography, fundamentally altering the dynamics of privacy, security, and governmental oversight on a global scale.

Technical Innovations of PGP

PGP introduced a robust, accessible encryption method to the general public, using a combination of asymmetric (public key) and symmetric encryption systems to enhance security and ease of use. The software implemented the RSA algorithm for its public key cryptography, which allowed users to encrypt data with a public key that could only be decrypted by a corresponding private key. For the actual data encryption, PGP used symmetric key cryptography, which was faster than asymmetric methods. The innovation did not stop there; PGP also introduced the use of digital signatures, allowing users to verify the integrity and origin of encrypted data.

One of the significant technical impacts of PGP was its use of a "web of trust," a decentralized trust model that allowed users to assign and verify the trustworthiness of public keys through a network of users rather than relying on a central authority. This approach was revolutionary in promoting user-driven security verification and managing public key authentication.

NSA's Concerns and the Broader Implications

The release of PGP did not go unnoticed by government entities, particularly the National Security Agency (NSA), which had long held a dominant role in cryptographic standards and intelligence gathering. The NSA and other law enforcement agencies were concerned about the implications of widespread access to strong encryption. Their primary fear was that encryption technologies like PGP would severely hinder their ability to conduct surveillance for national security purposes.

The concern was not unfounded. Before PGP, high-grade encryption was generally available only to government agencies and large corporations. By democratizing access to encryption technology, PGP enabled ordinary citizens to shield their communications from both governmental and non-governmental prying eyes. This shift posed a direct challenge to the NSA's capabilities, particularly in the areas of wiretapping and intercepting electronic communications, as encrypted content could not be easily decoded without access to the private keys.

Legal and Political Fallout

The distribution of PGP also led to significant legal and political repercussions for Zimmermann. Shortly after its release, Zimmermann became the subject of a criminal investigation by the U.S. government under the International Traffic in Arms Regulations (ITAR), which at the time restricted the export of cryptographic software deemed to be military-grade. The case highlighted the tension between national security interests and the right to privacy, stirring a global debate on the reach of U.S. export controls over software and the definition of "arms" in the context of cryptography.

Legacy and Continuing Impact

The controversy and subsequent legal battles surrounding PGP fueled a broader discussion about encryption, privacy, and civil liberties. It led to the relaxation of some export controls on cryptographic software in the late 1990s and helped pave the way for modern encryption protocols used over the internet, such as SSL/TLS for secure web browsing.

Moreover, PGP's influence extends beyond its technical contributions. It has played a crucial role in debates over privacy rights and surveillance, inspiring a new generation of encryption tools aimed at protecting individual privacy and securing communications in an increasingly digital world.

Conclusion

Phil Zimmermann's PGP software did not just provide a practical encryption tool—it sparked a significant societal shift towards individual privacy and security consciousness. The NSA's fears regarding the widespread availability of such technology underscore the ongoing tension between privacy rights and government surveillance capabilities. PGP remains a seminal work in the history of cryptography, symbolizing the power of individual empowerment against overarching surveillance.

Blockchain: what it is, how it works and the most common uses

What is blockchain?

It literally means blockchain is a database or public registry that can be shared by a multitude of users in peer-to-peer mode (P2P or peer network) and that allows the storage of information in an immutable and organized way.  

It is a term associated with cryptocurrencies because, apart from being the technology that supports them, it was born with the first virtual currency in history in 2009, Bitcoin . In this case, the data added to the blockchain is public and can be consulted at any time by network users.

However, it is important to remember that cryptocurrencies are just that, currencies! Just as happens with the euro, the dollar or any type of paper money. Each one is a simple material with a printed value, but what allows its use and generates value are the economic laws that support them.

Something similar happens with virtual currencies. In this case, it is blockchain technology that allows it to function. Its main objective is to create an unchangeable record of everything that happens in the blockchain, which is why we are talking about a secure and transparent system. 

Bitcoin (BTC), Ethereum (ETH) or any other cryptocurrency is simply a virtual currency built on the blockchain and used to send or receive the amount of money that each participant has. This technology is what keeps transactions publicly recorded, but keeping the identity of the participants anonymous.

However, although it was created to store the history of Bitcoin operations, over the years it has identified great potential to be applied in other areas and sectors due to the possibilities it offers.

Features of blockchain technology

The progress of this system has been a mystery since its origin, but little by little we are learning more details about its operation:

Security

Cryptography is a fundamental pillar in the operation of the blockchain application development company, which provides security for the data stored in the system, as well as the information shared between the nodes of the network. When we are going to make a transaction, we need a set of valid asymmetric keys to be able to carry it out on the blockchain. It is also known as public key cryptography.

Trust

By representing a shared record of facts, this technology generates trust in users. Not only that, but it eliminates the possibility of manipulation by hackers and generates a ledger of operations that all members of the network can access. 

Immutability

When information is added to the distributed database, it is virtually impossible to modify it. Thanks to asymmetric cryptography and hash functions, a distributed ledger can be implemented that guarantees security. In addition, it allows consensus on data integrity to be reached among network participants without having to resort to an entity that centralizes the information. 

Transparency

It is one of the basic requirements to generate trust. Transparency in blockchain consulting services is attained by making the chain's software code publicly available and by fostering a network of nodes that use it. Its application in different activities, such as supply chains, allows product traceability from origin.

Traceability

It allows knowledge of all operations carried out, as well as the review of transactions made at a specific time. Traceability is a procedure that allows us to follow the evolution of a product in each of its stages, as well as who, how, when and where it has been intervened on. This is one of the main reasons why many sectors are beginning to apply blockchain technology.

3 keys to understanding how the blockchain works

It will only take you a single step to become an expert on the blockchain consulting services. Now that you know its definition and the main characteristics and related terms, it is time to put everything you have learned together to discover how it works. Take note!

The jack, horse, king of transactions

Networks use peer-to-peer data exchange technology to connect different users who share information. That is, the data is not centralized in a central system, but shared by all users of the network. At the moment a transaction is made, it is recorded as a block of data transmitted to all parties with the objective of being validated. 

The transaction is the movement of an asset and the block can record the information of your choice, from what, who, when, to where, how much and how. Like an irreversible record, each block joins the preceding and following ones to form a chain (blockchain). Every new block removes the chance of manipulation and strengthens the previous one's verification. Finally, the transaction is completed. 

The structure of the blocks

The chain stores a lot of information, which allows it to grow over time. This is the reason why it has been necessary to create efficient query mechanisms without having to download all the information: the Merkle hash tree.

It is a tree data structure that allows a large number of separate data to be related to a single hash value, providing a very efficient method of verifying the contents of large information structures.

Generation of chain blocks

First of all, it is a decentralized process. And to do this, a distributed consensus is needed in which the nodes have the ability to generate valid data. In order for users to initiate new operations, they must turn into nodes within the system. If what they want is to become miners and create blocks, then they must compete with others. The validation process is based on asymmetric cryptography, with a public key and a private key. The issued transactions are validated by the nodes in the new mined block, as well as their correct linking to the previous block (it must contain the hash).

The most common uses of blockchain

“But this technology was created for cryptocurrency operations.”

That's right, but the passage of time, research and social needs have seen great potential in this technology to be applied in other areas:

Voting systems

Some states such as West Virginia are implementing electronic voting through blockchain, although it is still a framework to be regulated. But that's not necessary to go that far. After the last elections to the Madrid Assembly, as well as the COVID-19 pandemic situation and its restrictions on mobility and the gathering of people, they have proposed the establishment of electronic voting with blockchain.It is an extremely appealing voting system because of its traceability and immutability.Not only would it increase transparency and reliability, but you could audit in real time.

Smart Contracts

They are programs that allow you to fulfill and execute registered agreements between the parties automatically. They can be applied in any type of transaction where a registered agreement is necessary, such as a security deposit or the contracting of a product, among others. Among its main characteristics we find: self-execution and immutability. 

Supply chain

Supervision and monitoring in food chains, as well as in production, is one of the main applications proposed with blockchain. Some examples of this technology in the food and agricultural industry are: Walmart China, with food production constituted by IBM; or the Australian AgriDigital, which works with distributed ledgers, blockchain and Smart Contracts.

It is not what has already been done, but what is yet to come. At Occam Agencia Digital , as a blockchain development company, we are convinced that it is not just about programming, but about analyzing the client's needs and designing a unique user experience.

What are some ways that your business can benefit from blockchain technology? Tell us your questions, we can help you solve them.

Tokenization of real estate and assets

 Thanks to the transparency of the blockchain, the tokenization of assets is revolutionizing traditional sectors such as real estate investment, democratizing their purchase. 

This breaks the barrier to investing in safer assets, since, until now, if you wanted to buy a property, you had to do it alone or among a very small group of people. Thanks to tokenization, now you can buy an apartment between 100, 200, 1000 people by making a small contribution. 

This also allows you to diversify and minimize risk, being able to invest €100 in several properties.

It is very important to choose a blockchain development company that has developed a project using this technology, since these are complex developments with very little documentation on the internet to help developers.

How to do good blockchain development?

We invite you to take note of the steps necessary for the development of the blockchain:

The first thing to do is a briefing between both parties . The client provides the information on the business model, and the blockchain development company offers the expertise to design the platform using the most optimal technology.

It is very important to choose the technologies to be used, since in blockchain each transaction has a cost. Depending on the blockchain chosen, it can cost between €10 or €0.0001 each.

It is imperative that the blockchain development company determines which components of the platform need to function in order to have a well-balanced security, user experience, and cost per use system that is suitable and tailored to the client's suggested business model. 

For example, if you want to develop a platform to tokenize real estate so that investors can buy tokens from these, the most recommended thing is that all the functionality related to the purchase or investment is developed on blockchain technology, and the rest of the functionalities are developed using the traditional way. In this way, you will achieve a good user experience, great security in purchases and low costs.

Once the briefing is finished, we move on to the design phase . With the briefing in hand, it's time for the UX and UI experts to get to work. With the information collected, you must design a platform with a great user experience and a friendly interface to convey confidence to the user and allow them to operate very easily. You'll be able to stay on the platform and avoid getting frustrated or giving up.

[rendakuenthusiast]

Idly musing about post-quantum encryption algorithms. Suppose you had a system where there were public servers - effectively numbers stations - that constantly emitted a stream of random bytes (perhaps literally generated via radioactive decay), broadcast them publicly, and recorded them for a long period of time. Suppose also that any two parties that want to communicate negotiate a small shared secret out-of-band, say a 256-bit AES key. When Alice wants to send Bob an encrypted message, she records the current time from the numbers station, listens for bytes from the numbers station, and encrypts them with that shared secret. Alice then uses this new stream of random bytes as a one-time-pad and encrypts her message. When finished, she records the stop time and sends the encrypted message, start time, and stop time to Bob. Bob can use the start and stop times, his small shared secret, and the public records of the numbers station to reconstruct the stream of random bytes Alice used, and then XOR that against his received cyphertext to recover the plaintext. If there was a way to remove the initial small shared secret step, I think this sort of scheme would be a way that people could continue to do effective asymmetric cryptography even in a post-quantum world, albeit with the requirement that these numbers stations exist and keep records for a long period of time.

Post Quantum Security: Future-Proof Data From Quantum Threats

What becomes of encryption today when quantum computers are capable of cracking it? As we race toward a future driven by the next generation of technology, one urgent question hangs over cybersecurity. The solution is to use Post Quantum Security, a new generation of cryptography capable of resisting the brute power of quantum computing.

In a world where sensitive information — from personal identities to national secrets — is increasingly vulnerable, Post Quantum Security is not just an upgrade, but a necessity. This article explores how to future-proof your data and systems against quantum threats.

Understanding the Quantum Threat Landscape

The Birth of Quantum Computing

Quantum computing seems to quickly evolve from a new scientific theory into a change- and results-driven technology. Old computers use the binary digit as 0 or 1, whereas quantum computers operate using qubits, which can occupy several states simultaneously owing to superposition and entanglement. As a result, such cutting-edge machines provide an exceptional ability for quick, advanced computations.

Quantum computing excels using its capability of handling large data volumes and solving issues too complicated for existing best classical supercomputers. In particular, quantum computers can effectively address complex logistics tasks, analyze the structure of molecules to invent new medicines, and enhance the approach undertaken in financial forecasting.

But with that potential comes a warning: quantum computing puts modern cryptographic systems at serious risk. The same computational benefits that make quantum computers a breakthrough for scientific research are the ability to compromise classical encryption methods used in our online security.

Implications for Current Cryptography

The dominant modalities of the modern digital infrastructure are based on the use of public key cryptography, and such systems as RSA and ECC are among the most widespread representations that people use. These encryption systems are based on mathematically difficult problems for conventional systems — factorizing huge numbers or solving discrete logarithm problems. These are exactly the sorts of problems a quantum computer is designed to demolish with impunity using expert algorithms.

Shor’s Algorithm, created in 1994, is likely the most famous quantum algorithm that targets RSA and ECC directly. It can factor big numbers exponentially quicker than the best-known classical algorithms. When quantum computers are ready — usually called “quantum supremacy” — they will be able to decrypt secure communications, financial transactions, and private information that are now thought to be secure.

Another significant algorithm, Grover’s Algorithm, doesn’t shatter symmetric crypto systems but narrows down their security levels significantly. It indeed cuts a symmetric key’s bits in half, so 256-bit keys would provide only 128-bit security in the quantum age. Less devastating than Shor’s impact on asymmetric crypto, though, Grover’s Algorithm does mean a reconsideration of the dominant symmetric encryption algorithms.

This new threat brings to the forefront the need for post quantum security solutions in an immediate manner. Unlike conventional cryptographic practices, post quantum security is about designing and deploying algorithms that are secure even when quantum computing resources are available. These algorithms are based on challenging mathematical problems for which quantum computers are not yet known to solve efficiently.

The Urgency for Transition

Post quantum security is not a theoretical concept; it’s an urgent, real-life issue. RSA- or ECC-breaking large-scale quantum computers don’t exist yet, but breakthroughs are on the move. The collaborative efforts of governments, corporations, and research bodies across the globe to create quantum technology imply that these machines will soon become real.

There is a dire need to secure the digital infrastructure of organizations, for when quantum technology is available. Transitioning to post quantum security protocols is difficult and time-consuming, not only swapping cryptographic algorithms but also rewriting software, hardware, and communication protocols. Waiting for fully functional quantum computers may expose systems and data to attacks.

Further, hacked encrypted data today can be stored and decoded at a later date after computers develop the capability — the “harvest now, decrypt later” attack. As a countermeasure post quantum security ensures valuable information is safeguarded both today and in the foreseeable future.

The U.S. National Institute of Standards and Technology (NIST) has already started standardizing quantum-resistant algorithms with its Post-Quantum Cryptography Standardization Project. Organizations can standardize their security approach with international best practices for post quantum security using NIST-recommended solutions.

What Is Post Quantum Security?

Post Quantum Security is a term that is used to refer to cryptographic methods that are resistant to attacks carried out by entities that can run large quantum computers. Besides, this category includes the quantum-resistant hash algorithms, encryption algorithms, and digital signature algorithms. These systems are being standardized by efforts such as NIST’s Post-Quantum Cryptography Project.

Embracing Post Quantum Security guarantees that long-lived sensitive information, such as medical records or financial contracts, is still protected even when intercepted today and decrypted in the future quantum world.

ncog.earth incorporates Post Quantum Security into its core blockchain protocol. It provides data security for decades in a post-quantum secure environment.

Core Principles of Post Quantum Security

Below are the fundamental principles that constitute this new field and how they interact with each other to protect digital property during the era of quantum computing.

1. Quantum-Resistant Algorithms

Post quantum security is centered around quantum-resistant algorithms, which are designed to stand up to attacks both from traditional attack methodologies as well as attacks performed with a quantum computer. These algorithms don’t depend on the weak assumptions of the classical encryption methods like RSA or ECC, which can be attacked and broken by quantum algorithms like Shor. Post quantum security instead depends on mathematical problems with cryptographically amicable properties that are difficult for an efficient quantum computer to solve.

Among the most promising quantum-resistant solutions are-

Lattice-based cryptography: Lattice-based cryptosystems rely on the computational subtlety of such problems as the Shortest Vector Problem (SVP) and the Learning With Errors (LWE) problem. They are classical and quantum resistant and thus well positioned to protect encryption, digital signatures, and key exchanges.

Hash-based cryptography: Founded on extensively studied hash functions, this method effectively generates secure digital signatures. Because hash functions are one-way functions, they are extremely secure even against quantum attackers.

Code-based cryptography: Founded on error-correcting codes, this method has stood the test of time for more than four decades. It is strong, well-established, and extremely efficient for encryption and digital signatures in a post quantum security scenario.

Multivariate polynomial cryptography: The hardness of these problems is essentially dependent on the intricacies of solving multivariate quadratic systems of equations, which are intractable for quantum and classical systems.

Deployment and selection of these algorithms are being standardized by bodies such as NIST, which is finalizing a suite of post-quantum cryptographic standards for ease of global implementation of post quantum security protocols.

2. Forward Secrecy

Forward secrecy is yet another significant post quantum security parameter. In the conventional crypto paradigm, it might be possible that breaking a private key today can expose attackers to decrypted communications in the past and future, and it is highly risky if, in a quantum paradigm where harvested encrypted data from today can be broken using quantum computers in the future.

Post quantum security addresses this issue by guaranteeing that even when an encryption key is finally breached, past messages cannot be decoded after the fact. The method is to repeatedly generate ephemeral keys that don’t survive and aren’t easily linked up with each other. Forward secrecy is significant not just for private individuals but for protecting business networks, government files, and money networks as well.

Essentially, forward secrecy reconfigures the way we approach long-term data secrecy, particularly considering the danger represented by “harvest now, decrypt later” attacks facilitated by quantum advancements. In post quantum security, it’s a solid pillar of real future-proofing.

3. Hybrid Cryptographic Models

With the indefinite time frame of quantum progress, most organizations are taking a hybrid approach that brings together classical and post-quantum-resistant cryptography. The cryptographic models are created to fill the security gap during the transition phase when the existing traditional algorithms exist side by side with the post quantum security algorithms.

In a hybrid method, two sets of algorithms are run in parallel. One set offers backwards compatibility with current infrastructures, and the other offers immunity to future quantum attacks. As a simple example, an end-to-end communication channel could employ RSA in conjunction with a lattice-based encryption scheme at the same time. This means that even if the classical part is compromised in the future, the post quantum security layer still protects the underlying data.

This method has some advantages-

Gradual roll-out: Businesses can deploy systems gradually without affecting current services.

Redundancy: Having several levels of encryption offers a backup in case one algorithm is compromised.

Testing ground: Testing the deployment of quantum-resilient tools identifies real-world problems and solutions before mass deployment.

Hybrid deployments are not long-term, but they are essential stepping stones. With increasing trust and confidence in post quantum security technology, hybrid deployments will ultimately make way for fully quantum-resistant architectures.

Why Businesses Must Act Now

In the unfolding digital age, while cyberattacks increase in scale and sophistication, quantum computing’s emergence is at once a dazzling technological advancement and an intrinsic cybersecurity challenge. To companies — particularly those holding sensitive customer data or conducting business in highly regulated industries — the time to prepare is not in the future but today. Post-quantum security is no longer an idealistic aspiration but rather a concrete reality. Forward-thinking companies need to take action today to ensure that they will be able to withstand future cryptographic shocks.

Quantum Threats Are Nearer Than They Seem

The power of quantum computers is that they can use superposition and entanglement to exceed classical machines in certain forms of mathematical operations. The possible advantages that such technology could offer to drug discovery and logistics, as well as machine learning, are substantial, but this danger also undermines the encryption protection that enshrines secure digital communication, financial systems, medical records, and contracts.

Algorithms such as RSA and ECC, the basis of modern public-key cryptography, could be made obsolete by quantum algorithms such as Shor’s. In practical terms, what that would mean is to make information currently encrypted under these systems decrypted within seconds if there existed a sufficiently large quantum computer. The potential effect would be disastrous to companies experiencing huge-scale data breaches, litigations, and erosion of customer confidence.

That’s why post quantum security must be implemented far ahead of the wholesale arrival of quantum computing. Companies that delay are not only taking a risk — they’re deliberately putting their businesses, data, and reputations in long-term jeopardy.

Data Longevity Brings the Risk into the Present

One of the least considered measures of quantum risk is data longevity concern. Whereas real-time data spoils at a fast pace, some forms of data — medical history, legal papers, government agreements, and intellectual property — are priceless for decades or years. If today a cyberattacker got hold of encrypted information, they would be unable to decipher it. But with the advent of quantum power, the same information can be accessed in the foreseeable future. The label is also applicable when talking about attacks referred to as “harvest now, decrypt later”.

On this front, post quantum security plays a twofold role: it safeguards against the threat at hand, but also against potential attempts to decrypt in the future. For businesses tasked with securing data over the long term — insurance providers, banks, and law firms, for example — it is critical that it is pre-emptive. Delaying the implementation of quantum-resistant practices creates a bombshell situation where encrypted files stored could be cracked open at any moment.

Consumer confidence is perhaps the most precious asset of the online marketplace. With high-profile breaches becoming the norm, customers are growing more attuned to where their information lives and how it is secured. Companies that act early to publish quantum security standards communicate that they are serious about leading-edge data protection and customer privacy. This method contributes to the creation and preservation of a reliable brand and earns the loyalty of the clients.

Additionally, regulatory landscapes are changing. Global data privacy legislation like the GDPR, HIPAA, and CCPA demands secure data security procedures, and compliance systems will shortly be following close behind in counteracting quantum-age attacks. Adopting post quantum security today allows organizations to protect themselves against future compliance mandates and sidestep the prohibitively cost-intensive exercise of currency flows.

Smooth Transition Through Strategic Planning

Post quantum migration is not a flip-of-the-switch transition — it requires thoughtful planning, testing, and staged deployment. Businesses must assess their existing cryptographic infrastructure, identify vulnerable endpoints, and decide which quantum-resistant algorithms will best meet their operational needs.

Fortunately, most businesses are not beginning from the ground up. Hybrid crypto designs — blends of conventional and quantum-resistant solutions — permit phased and secure adoption. Post quantum security is viable through hybrid approaches that support organizations in adopting post quantum security without sacrificing current system performance or compatibility. Phase by phase is the way, causing as little disruption as possible while providing security for important information at each stage.

They also must spend on training and awareness programs. Decision-makers, developers, and cybersecurity staff must be made aware of the effects of quantum risk and the pragmatic actions that go into minimizing it. Post quantum security incorporated into cybersecurity roadmaps now will have companies not lag when the quantum era is in full force.

Building Quantum-Resilient Ecosystems

The truth is, cybersecurity is not an isolated practice. A majority of businesses employ third-party suppliers, cloud computing providers, and digital platforms that touch or have access to sensitive information. Having a secure digital environment is a matter of discussing post quantum security with partners and suppliers.

Leading organizations are now starting to measure their supply chains and expect quantum-readiness from their partners. Organizations can minimize systemic vulnerabilities and foster increased collective resilience by establishing post-quantum security as an expectation within ecosystems.

Integrating Post Quantum Security into Your Infrastructure

With continued advances in quantum computing, the danger that it poses to classical cryptographic schemes is more dire. Companies and enterprises cannot afford to wait. There is a need for a transparent and systematic adoption of post quantum security protocols into existing IT infrastructures so that data confidentiality, integrity, and availability are preserved under quantum computing. This has to be done with a strategic roadmap of action covering technology and operations transformation across the digital landscape.

For this transition to be made possible, organizations can utilize a multi-step process that will establish quantum resilience without disrupting essential services. Below, we outline the four main steps of incorporating post-quantum security in your infrastructure.

Audit Your Current Cryptographic Inventory

Before any change is implemented by companies, they must start by defining the scope and utilization of current cryptographic assets. Any effective post quantum security project is based on a thorough cryptographic inventory. This process entails determining where and how cryptographic algorithms are utilized — on SSL/TLS certificates, database encryption, secure email, authentication protocols, digital signatures, API gateways, mobile applications, VPNs, and IoT devices.

This audit must encompass-

Encryption Algorithms Used: Assess if systems are using RSA, ECC, or other vulnerable algorithm-based encryption.

Key Sizes and Expiration Policies: Document existing key sizes and assess how often they are being replaced.

Cryptographic Libraries and APIs: Check for dependencies and assess compatibility with quantum-resistant alternatives.

Certificate Authorities and Issuance Policies: Examine methods of distributing, retaining, and withdrawing digital certificates.

When such data is analyzed, it is possible to identify weak points and establish priorities for strategic transition to post-quantum security. Notably, the process helps organizations to review the data lifecycle and determine long-term sensitive data that needs to be secured today against tomorrow’s quantum decryption power.

Select Quantum-Resistant Algorithms

After identifying your cryptographic footprint, the next step is to select quantum-resistant alternatives. NIST has worked with others to initiate multi-year standardization efforts that will evaluate and promote post-quantum cryptography algorithm recommendations. These algorithms are designed so that they can resist attack by both classical and quantum computers and include key encapsulation processes and digital signature protocols.

Among the most promising contributions to come out of the NIST project are-

CRYSTALS-Kyber (for public-key cryptography and KEM)

CRYSTALS-Dilithium (for digital signatures)

FALCON and SPHINCS+ (signature schemes with performance profiles of differing types)

In choosing algorithms, implementations must consider performance, resource efficiency, complexity to implement, and the extent to which the solution they choose fits their infrastructure. For instance, IoT devices that have little power may need lightweight algorithms, but high performance servers are more than capable of handling complex computing activities.

Selection of the best algorithms is immensely important for effective post quantum security integration. Future-proofing should also be a consideration for security teams as quantum-resistant cryptography develops. Modular architecture solutions for cryptography allow for a seamless switch or upgrade of algorithms as new standards become available.

Use Hybrid Cryptographic Systems

It is not necessary to move away from classical to quantum-resistant cryptography completely. One of the most recommended practices while transitioning to post quantum security is the use of hybrid cryptographic systems. These use current (classical) cryptographic algorithms and couple them with quantum-safe algorithms to provide a multi-layered defense.

In a hybrid system, data is encrypted with both RSA (or ECC) and a quantum-resistant algorithm. It makes the system both backward compatible as well as future-proof against attacks based on quantum. Although quantum computers are unable to break today’s classical encryption now, hybrid encryption protects the data from being exposed in the future, most beneficial for long-shelf-life sensitive data.

Hybrid deployments also enable companies to pilot the in-the-wild usage of post-quantum-safe algorithms without removing trusted current defenses. Phase-in of post quantum security in this manner prevents service disruption, lowers operational risk, and enables incremental testing and tightening.

Key libraries and frameworks increasingly start to include hybrid support. For example-

OpenSSL (with quantum-safe branches)

Cloudflare and Amazon Web Services, which have begun to experiment with post-quantum TLS deployments

Mozilla and Google, pioneering early hybrid deployments in their browsers

These initial hybrid adoption attempts show the growing traction for post-quantum security and offer in-the-wild blueprints for companies willing to make the transition.

Upgrade Key Management Systems (KMS)

The key to the efficiency of encryption lies entirely in the responsible use of its keys. Infrastructures that are quantum-resilient need updates to legacy Key Management Systems (KMS) to accommodate the special needs of post quantum security…

How Blockchain Secures Data Through Cryptography

In this episode of Unpacking Blockchain Technology, we explore one of the most critical components of blockchain: cryptography — the invisible shield that protects digital data, ensures transaction integrity, and powers trustless systems.

What Is Cryptography, and Why Does It Matter?

At its core, cryptography is the science of secure communication. It converts data into a coded format that only authorized parties can understand. In the world of blockchain, cryptography ensures that:

Transactions are secure and tamper-proof

Identities are protected

Data cannot be altered retroactively

Without cryptography, blockchain as we know it simply wouldn’t work.

Two Key Types of Cryptography in Blockchain

1. Hashing (e.g., SHA-256): Every piece of data in a blockchain is run through a hash function. This generates a fixed-length string of characters (the hash) that acts like a digital fingerprint. Even the slightest change to the data produces a completely different hash, ensuring data integrity.

2. Public-Key Cryptography (Asymmetric Encryption): This system uses two keys: a public key (shared with others) and a private key (kept secret).

You sign a transaction with your private key

Anyone can verify it using your public key

This mechanism ensures authenticity, non-repudiation, and secure value transfer between users.

Real-World Application: Bitcoin and Ethereum

In Bitcoin, each transaction is hashed and linked to the one before it — creating an unbreakable chain of trust.

In Ethereum, cryptography also secures smart contracts, automating interactions without revealing sensitive data.

Why Should You Care?

Whether you’re a developer, investor, policymaker, or just blockchain-curious, understanding cryptography helps you appreciate how:

Blockchain eliminates the need for third-party trust

Transactions stay secure, verifiable, and transparent

Your digital identity and assets are protected in Web3

Cryptography isn’t just a technical feature — it’s the foundation of digital trust in decentralized systems.

Tune in to Episode 7 now to demystify the cryptographic magic behind blockchain security.

Cryptography: The Science of Securing Digital Information

Data security is now a top concern in today's digital environment. Whether it's online banking, social media, or business transactions, protecting sensitive information is essential. Here's when cryptography comes into play. Cryptography is the science of encrypting and decrypting data to ensure that only authorized users can access it. From securing personal messages to safeguarding national security, cryptography has become a fundamental pillar of cybersecurity.

What is Cryptography?

Cryptography involves transforming data into an unreadable format (ciphertext) using encryption techniques. The data can only be converted back into its original form using a special decryption key. This guarantees that hackers will be unable to decode the data even if they manage to intercept it.

With advancements in technology, cryptography has evolved from simple manual ciphers to highly complex mathematical algorithms. Today, it is widely used in securing emails, online banking, cloud storage, and digital signatures.

Types of Cryptography

Symmetric Cryptography: Uses a single key for both encryption and decryption. It is fast but requires secure key-sharing between sender and receiver.

Asymmetric Cryptography: Uses two keys—one public and one private. It is commonly used in secure email communication and digital signatures.

Hash Functions: Converts data into a fixed-length hash value that cannot be reversed. It is used to store passwords and secure blockchains.

The Importance of Cryptography in Cybersecurity

As cyber threats increase, cryptography has become essential in securing sensitive information. Here’s why cryptography is crucial:

Data Privacy: Prevents unauthorized access to critical information.

Authentication: Ensures that only legitimate users have access to data.

Data Integrity: Detects any alterations or tampering in sent data.

Secure Communication: Protects digital interactions from cyber threats.

Cryptography in Online Transactions

Cryptography plays a significant role in securing online transactions. It ensures the safety of financial transactions by encrypting credit card details and personal information. Online banking and digital payments would be extremely vulnerable to fraud if encryption were not used.

In the e-commerce industry, cryptographic techniques such as SSL/TLS encryption secure transactions, protecting users from cyber threats like phishing and identity theft.

Cryptography in Blockchain and Cryptocurrency

Blockchain technology relies heavily on cryptography for security. Digital currencies like Bitcoin and Ethereum use cryptographic hashing and digital signatures to secure transactions. Each transaction is encrypted, making it nearly hard for hackers to alter the data.

Digital signatures verify the authenticity of transactions, ensuring that only the rightful owner can access and transfer digital assets. This makes cryptography a critical element in securing decentralized financial systems.
