IPsec incorporates several cryptographic operations to ensure message authenticity, data integrity, and sender nonrepudiation. In this section we will describe the mechanics of these cryptographic ...

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

The National Institute of Standards and Technology (NIST) has opened a competition to develop a new cryptographic "hash" algorithm, a tool that converts a file, message or block of data to a short ...

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature. This shows that the algorithm ...

The nice thing about standards is that there are so many to choose from. And if you really don't like all the standards you just have to wait another year until the one arises you are looking for. -- ...

The original author of the MD5 password hash algorithmhas publicly declared his software end-of-life and is "no longer considered safe" to use on commercial websites. This comes only a day after a ...
