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 ...

This standard specifies hash algorithms that can be used to generate digests of messages. The digests are used to detect whether messages have been changed since the digests were generated. This ...

An algorithm that transforms a given amount of data (the "message") into a fixed number of digits, known as the "hash," "digest" or "digital fingerprint." Hash functions are a fundamental component in ...

Louvain‐la‐Neuve, Belgium, May. 24, 2017 – Barco Silex, leading provider of IP cores for embedded security, has added the new SHA-3 hashing functions to its extensive offering of IP blocks. Hashing ...

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 ...
