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 ...

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, ...

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 ...

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 ...

A digital signature, an asymmetric cryptography is designed using VHDL. The implementation has a Message Digest block and a RSA block. Implemented Digital Signature Algorithm on a Spartan 3 FPGA board ...

Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash ...
