Digital Signing and Digital Stamp

Each new digital device turns out to be better than the previous ones. When it comes to the digital world and what it can do for us, the wonders haven’t stopped. A new milestone is crossed with a new invention and life keeps becoming easier for everyone. But modern technology is as remarkable as scary the modern crimes are. People discover new ways to do evil things. In today’s age, nothing is more valuable than information. The Cambridge Analytica scandal is still fresh in everyone’s mind when targeted ads changed people’s opinion about election candidates. Who can say our data is secure even after Cambridge Analytica was shut down? Computers and the internet not only make it easier for us to connect with each other but also give criminals a better chance of stealing our information. All of us are so quick to give apps permission and in a world where everyone is using a new application, it is hard to stay away. So, when our data gets stolen and used to manipulate us, who can we blame really? A lot of people have tried to warn the public about the information they casually share online and how it can be used against all of us. Even the documents we received via email can be fake and trick us into thinking they are the real deal. A lot of businesses suffer from damages every year due to fake information. Identity theft is also a huge problem for both individuals and companies. You can receive messages from anyone claiming to be one of your business partners and you will have no quick way of confirming it. If it is one of your business partners, they will get offended at you doubting their message and delaying their request, and if it is not them and you act on your request, it will be a problem for your company. The best solution of this problem is digital signature.

The Importance of Digital Signature:

Gone are the days when we used to waste paper for storing records and fill up rooms with boxes full of files. Nowadays, all the information is stored in computers but the problem with that is the lack of signatures, without which a document has no official value. Some companies print the document, sign it, and then scan it to make them official. But that process only wastes more paper and ink and can be easily used for fraud. This is why digital signature is a lot better option. Not only it saves time and money but also ensures extra safety of personal documents. Digital signature has changed the way companies handle information and important documents. Papers can be signed easily by people without having to worry about fraud. But there are different types of digital signing process and not all of them are equally beneficial. The more information a system requires for a digital signature, the more reliable it will turn out to be.

Digital Signing and Digital Stamp:

If you only ask for a signature from a signer, it can be easily forged by anyone. You will have no way to confirm the validity of the signature. You would be compelled to think it is the real thing. But it can very easily be fake. This is why a better digital signing and time stamp process was required. With the help of a new app, digital signing has become a lot more than a signature. There is a lot of things that a document will require before it can be considered signed by the signer. The digital stamp will list the exact time the document was signed. All of these steps will help ensure the authenticity of the signing and eliminate the chances of forgery.

Certificate of Evidence:

A simple digital signature may not make a document legal, but a multiple signature method will. It is important for businesses that their documents have a legal status. If a signature cannot hold in the court, it will only cause problems for the business and not the signer. This is why it is important for companies to ensure that the process of signing they have chosen will be acceptable in a court. A certificate of evidence is what assigns a legal status to a document. But what exactly is a certificate of evidence? It includes all the authentications you and the signer had agreed upon and their digital signature. The authentications often include a picture of the signer’s driver license, their selfie, their signature and their GPS coordinates. When you have received all the information from them, it will show up on the certificate of evidence. The certificate will make the document they signed legal, which means it can be presented in a court with full confidence in its authenticity. Things can easily get complicated for businesses over small issues. Having fake signatures from someone can easily mess things up, not to mention the consequences of actions taken on the basis of such documents. Which is why it is wise to stick to the safest method of digital signing and digital stamp. The certificate of evidence makes thing very easy for both the signer and the businesses. The modern criminals may be getting better at their job, but our efforts to keep them away from personal information are also improving. With the help of modern technology, we can keep improving our security and eliminate all chances of fraud. Read the full article

Week 5 Evening Lecture

Extended seminar - OPSEC (Operations security)

Don’t share any sensitive information that is meant to be kept a secret in public.

Hide your identity - remain anonymous by setting up a fake identity, using a browser such as Tor - keep a low profile 

Be forgettable - blend in, don’t stand out

Extended seminar - Passwords

Most passwords used are weak. It’s hard to remember a strong password, and that is the reason why many people don’t use them.

Weak passwords often have personal information such as name and birthday in them, making it very easy for hackers to crack.

Strong passwords are long without English grammar patterns.

Merkle Damgard construction

https://en.wikipedia.org/wiki/Merkle%E2%80%93Damg%C3%A5rd_construction

This is a method of building collision-resistant cryptographic hash functions from collision-resistant one-way compression functions.

It is used in hash algorithms such as MD5, SHA1, and SHA2.

The message is split up into blocks.

The algorithm starts with an initial value, the initialisation vector (IV).

The result so far (initially just the IV) is combined with the next message block, then the compression function f is applied.

Step 3 is repeated until all blocks have been added.

The last result may be passed through a finalisation function.

Length extension attack

An intercepted message with known hash and message length can be extended. 

Take the hash, append a new message to it and pass it into f, the compression function. This is modifying the message, even without needing to know the secret key.

HMAC (hash-based message authentication code) puts the password after the message, instead of the beginning. h( key | h(key|m) )

Digital Signature

DSA - Digital Signature Algorithm

https://en.wikipedia.org/wiki/Digital_signature

A digital signature is used to verify the authenticity of digital messages or documents. A valid digital signature gives the recipient strong reason to believe the message was truly from the sender (authentication) and that the message was not altered in transit (integrity).

To sign large files, hash the file and then sign the encrypted hash because if signing it directly it will take a long time.

Collisions with digital signatures

A collision attack requires half the number of bits in the hash size.

Alice signing “I will give Bob $100″ document, and sends it along with the signature to Bob.

An attacker can possibly create another document with the exact same hash as Alice’s document except the amount is changed from $100 to $1000 and it will look like Alice has signed the new document.

The attacker can change 1 bit in each document that will change the hash (e.g. whitespace) and then keep hashing until the attacker finds 2 identical hashes. 

Ask Alice to sign the first document, and you can reuse the signature for the second one.

Passwords

Two types of password attacks:

online: typing in the password 

offline: obtaining the file containing hashes of passwords and decrypting locally

Salt is random data added to the password before hashing. It helps to prevent collisions in the case that users have the same password. Furthermore, it protects against the use of rainbow tables because the passwords are hashed with the random salt.

Big Advantages of Using Electronic Signatures

Electronic signatures refers to the process of attaching encoded signatures to an electronic document. Electronic signatures are actually legally binding that’s based on the U.S. Electronic signatures on Global and National Commerce Act (E-SIGN) and was enacted by the congress back in 2000. This is able to help companies just tied to paper in executing contracts and that the resulting process improvement and cost savings are substantial.  Click here to learn more : https://www.chilefirmas.cl/.

Before electronic signatures were recognized legally, all of the contracts needs to be signed, faxed, shipped, filed and scanned. This process however will need multiple steps which can be time consuming, costly and must be avoided as possible to be in favor of electronic signatures. Learn about  firma digital  here.

Increased Contract Speed

As an example in such case where a healthcare provider with a contract management software could use electronic signatures in speeding up the process of execution for time-sensitive contracts which affects patient care critically. An electronic signing could in fact prevent any delays that are unnecessary to finalize contracts that then leads to improved performance. Healthcare professionals, just like any other professionals don’t need to worry and wait for paperwork to be shuttled for the signatures before a contract is put in place.

Some of the ways on how electronic signatures could help to speed up the contract process are as follows:

Digital signatures are good for the life of the contract and avoids repetitive signing.

Negotiations are accelerated due to the reason that every step is being authenticated and can be accessed by all of the parties so that any critical problem could be flagged and be tracked until the final execution.

When every parties are geographically diverse, the signatures are implemented electronically in order to avoid any delays on updating as well as executing contracts.

Improved Security

Another benefit that electronic signatures have would be the fact that there’s less worry when it comes to security compared to paper. A contract management software that comes with electronic signing capability is able to automatically detect minor altering and also record more data points compared to paper.

Transaction Costs are Low

Another addition of its advantages would be on its cost savings. Automated processes of an electronic signature will help reduce financial impacts of human errors like signing mistakes, which actually slows down the process of perhaps cause an eventual problem that’s costly when it is undetected. An electronic signature software will help to mitigate the risks through giving you alerts on any suspicious records or any compliance issue that’s involved with the contract.

You will in fact also be able to save a lot on items like paper, packaging, copying as well as in shipping. Not only that, you also could save on labor, material costs and is very efficient.  Read more now : https://en.wikipedia.org/wiki/Digital_signature.
