Triple DES definition in Computer Security terms:

Acronym(s): 3DES

Definition(s): Triple Data Encryption Algorithm, specified in [SP 800-67].
Source(s): NIST SP 800-57 Part 3 Rev. 1 (NIST SP 800-67)

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. Triple DES provides much stronger encryption than ordinary DES but it is less secure than advanced encryption standard (AES).
