NIST updates Federal Information Processing Standard (FIPS) for secure hash standard to include additional algorithms. (General Development).On Aug. 1, 2002, the Secretary of Commerce approved FIPS (Federal Information Processing Standards) A series of publications issed by the U.S. National Institute of Standards and Technology (NIST) that specifies information security guidelines for federal government departments and agencies. 180-2, Secure Hash Standard The Secure Hash Standard (SHS) is a set of cryptographically secure hash algorithms specified by the National Institute of Standards and Technology. The SHS standard specifies a number of Secure Hash Algorithms (SHA), for example SHA-1, SHA-256 and SHA-512. (SHS SHS Shares (stock) SHS SAW (Surface Acoustic Wave) Humidity Sensor SHS Sciences Humaines et Sociales (French: Social Sciences) SHS Student Health Service SHS Second Hand Smoke ). The standard replaces FIPS 180-1, which was issued in 1992. FIPS 180-1 specified an algorithm (SHA-l) for producing a 160 bit output called a message digest. A message digest is a condensed representation of electronic data and is used in cryptographic processes, such as digital signatures, message authentication, and the generation of random numbers. FIPS 180-2 includes three additional algorithms, which produce 256 bit, 384 bit, and 512 bit message digests. These expanded capabilities are compatible with and support the strengthened security requirements of FIPS 197, Advanced Encryption Standard (cryptography, algorithm) Advanced Encryption Standard - (AES) The NIST's replacement for the Data Encryption Standard (DES). The Rijndael /rayn-dahl/ symmetric block cipher, designed by Joan Daemen and Vincent Rijmen, was chosen by a NIST contest to be AES. .
