Abstract

[Withdrawn May 19, 2005] The Data Encryption Standard (DES) was published as Federal Information Processing Standards Publication (FIPS PUB) 46 on January 15, 1977. The DES specifies a cryptographic algorithm for protecting computer data. FIPS PUB 81 defines four modes of operation for the DES which may be employed in a wide variety of applications. These guidelines are to be applied in conjunction with FIPS PUB 46 and FIPS PUB 81 when implementing and using the Data Encryption Standard. They provide information on what encryption is, general guidance on how encryption protects against certain vulnerabilities of computer networks, and specific guidance on the DES modes of operation in data communications applications. When used with the proper administrative procedures and when implemented in accordance with these guidelines, electronic devices performing the encryption and decryption operations of the standard can provide a high level of cryptographic protection to data in computer systems and networks.
