This core is a full implementation of the Triple DES encryption algorithm. Both encryption and decryption are supported. Simple, fully synchronous design with low gate count.
The X_3DES core is a full hardware implementation of the triple DES algorithm as described in the X9.52 standard, suitable for a variety of applications.
The triple DES algorithm was proposed by IBM when it became clear that the security of the DES had been compromised by advances in computer technology.
Compared to the DES algorithm, the triple DES algorithm provides a much higher level of security.
Each triple DES encryption/decryption operation (as specified in ANSI X9.52) is a compound operation of the DES encryption and decryption operations.
