Triple DES Is Now A Federal Standard.Following a recommendation from the federal government's National Institute of Standards and Technology National Institute of Standards and Technology, governmental agency within the U.S. Dept. of Commerce with the mission of "working with industry to develop and apply technology, measurements, and standards" in the national interest. , the Secretary of Commerce has revised the Data Encryption Standard See DES. Data Encryption Standard - (DES) The NBS's popular, standard encryption algorithm. It is a product cipher that operates on 64-bit blocks of data, using a 56-bit key. It is defined in FIPS 46-1 (1988) (which supersedes FIPS 46 (1977)). , which federal agencies and others use to scramble sensitive information. The revision involves using the DES algorithm in three successive operations, a technique known as Triple DES See DES. (cryptography) triple DES - A product cipher which, like DES, operates on 64-bit data blocks. There are several forms, each of which uses the DES cipher 3 times. Some forms use two 56-bit keys, some use three. The DES "modes of operation" may also be used with triple-DES. . The revised standard applies to federal agencies that use encryption to safeguard sensitive, unclassified un·clas·si·fied adj. 1. Not placed or included in a class or category: unclassified mail. 2. information. The original version was first approved in 1977 and has since been revised several times. Under the latest revision, agencies buying cryptographic products will be required to purchase equipment that supports the use of Triple DES for new systems. Agencies should also be developing plans to phase out the use of single DES in existing systems. Triple DES, which offers a much higher level of security than single DES, is intended to bridge the gap between DES and the future 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. , which is under development by NIST's Information Technology Laboratory. AES is being designed to provide strong cryptographic security well into the 21st century. |
