In this chapter we will look at choosing and optimizing cryptographic algorithms, particularly for resource-constrained systems, such as embedded systems. We will look at various strategies for ...

The National Institute of Standards and Technology today announced a public competition to pick a new cryptographic hash algorithm that would become the new federal information processing standard.

COMMENTARY--I can imagine a world where the computers needed no security. Where there were no passwords, no security checks, and no firewalls. Where the computers communicated freely and shared ...

Chaotic hash functions represent a cutting‐edge convergence between nonlinear dynamics and cryptographic science. These functions employ chaotic maps—mathematical systems that exhibit extreme ...

Passwords are the keys to our online identities, and as a result, they’re also near the top of the target list for attackers. There have been countless breaches in the last few years in which ...

Why upgrade if PQ signatures are not yet proven?The dirty secret of efforts to upgrade blockchains to post-quantum ...

Hashing and Encryption, do you know what these are? Some might have heard the names before and believe they are the same. But that is not the case at all. You see, much of the data that is moving ...

Cryptography secures digital data using algorithms, essential in private secure communications. Cryptos use cryptographic methods like asymmetric encryption and hash functions for transactions.

I’m going to talk about the security behind Bitcoin addresses and keys, called Public Key Cryptography. This includes SHA256, Random Number Generators(RNGs), Hash Functions, and Elliptic Curve Digital ...
