The SHA-1 and MD5 algorithms are the two most common cryptographic hash functions in use today. The more recently introduced SHA-224 and SHA-256 hash algorithms have been approved by National Institute of Standards and Technology (NIST) for future hash algorithm requirements as the security of both MD5 and SHA-1 have been called into question. Hash algorithms are typically used in message authentication and digital signature applications, where a message or file requires tamper protection or origin authentication. In particular, a hash algorithm is commonly used to perform message authentication as part of the Internet standard HMAC which is used in a number of secure network protocols such as IPsec and SSL. The Helion Tiny Hashing core has been designed to implement SHA-1, SHA-224, SHA-256 and MD5 in Xilinx technology with the added bonus of native HMAC support to provide a flexible, resource efficient hash solution for data rates up to 50 Mbps.
