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 ...

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

Download this article in PDF format. On the surface, this sounds ridiculous: A lobby fish tank gets attacked by hackers. Why would anyone want to break into a fish tank (Fig. 1)? But in this case, the ...

SHA-1, a cryptographic hash function first developed in 1995, is used for producing hash "digests," each 40 hexadecimal characters long. The digests are meant to be distinct for every message, file ...

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 ...

The National Institute of Standards and Technology (NIST) this week 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 ...
