Symmetric Key Hardware Accelerator
(SKHA)
28.1
The Symmetric Key Hardware Accelerator (SKHA) is a cryptographic hardware coprocessor
designed to implement two widely used symmetric key block cipher algorithms, AES (Advanced
Encryption Standard) and DES (Data Encryption Standard).
28.1.1 Features
The SKHA supports the following block ciphers:
28.1.2 Modes of Operation
The SKHA module can encrypt and decrypt the following security algorithms and cipher modes:
28.1.2.1 Data Ecryption Standard (DES & 3DES) Algorithm
The SKHA is able to perform bulk data encryption/decryption in compliance with the Data
Encryption Standard algorithm (ANSI x3.92, FIPS 46-2), as well as 3DES, which is an extension
of the DES algorithm.
