Its successor is called Advanced Encryption Standard ( AES). What is DES encryption DES is a symmetric block cipher (shared secret key), with a key length of 56-bits. Data Encryption Standard (DES) is the symmetric block cipher which encrypts a 64-bit plain text in a 64-bit ciphertext. In the 1990s DES was not considered save enough anymore due to its limited key length. This updated version, 3DES, encrypts the data three times with three different keys. To enhance the data protection an updated version of DES is developed. However, free versions of the software are widely available on the Internet. government had prevented export of software wich uses the DES algorithm. Concerned that the encryption algorithm could be used by unfriendly governments, the U.S. Secretary of Commerce Carlos Gutierrez recently approved the withdrawal of the Data Encryption Standard (Federal Information Processing Standard 46-3) and two related standards that provide for the implementation and operation of the DES. National Institute of Standards and Technology (NIST) as a Federal Information Processing Standard. NIST Withdraws Outdated Data Encryption Standard. Both the sender and the receiver of the encrypted message use the same private key.ĭES was originally developed by IBM in 1977 and was adopted by the U.S. DES uses a 56-bit key on each block of 64-bits of data. Triple DES provides much stronger encryption than ordinary DES but it is less secure than advanced encryption standard (AES). DES - Data Encryption Standard - 3DES - Triple Data Encryption Standard - Telecom ABC DES - Data Encryption Standardĭata Encryption Standard (DES) is a data encryption algorithm for the protection of electronic data. Definition (s): An implementation of the data encryption standard (DES) algorithm that uses three passes of the DES algorithm instead of one as used in ordinary DES applications.
