Data Encryption Standard

See DES.

data encryption standard [′dad·ə en‚krip·shən ′stan·dərd]

(communications)

A cryptographic algorithm of validated strength which is in the public domain and is accepted as a standard. Abbreviated 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)). DES is identical to the ANSI standard Data Encryption Algorithm (DEA) defined in ANSI X3.92-1981.

DES has been implemented in VLSI. SunOS provides a des command which can make use of DES hardware if fitted. Neither the software nor the hardware are supposed to be distributed outside the USA.
