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 ...

Cryptography aficionados, say hello to a new hash algorithm backed by the National Institute for Standards and Technology (NIST). Dubbed Keccak (pronounced "catch-ack"), the secure hash algorithm, ...

The National Institute of Standards and Technology (NIST) today announced the winner of its five-year competition to select a new cryptographic hash algorithm, one of the fundamental tools of modern ...

This standard specifies secure hash algorithms, SHA-1, SHA-224, SHA-256, SHA-384, SHA512, SHA-512/224 and SHA-512/256. All of the algorithms are iterative, one-way hash functions that can process a ...

A replacement for one of the most-used algorithms in computer security has finally been chosen after a competition between cryptographers that ran for five years. The competition was designed to ...
