DES channel
This Channel can compute DES and 3DES encryption and decryption in ECB and CBC
mode; executing C3 Flow type DES [START/APPEND] instruction.
Instruction set
The DES Channel executes DES [START/APPEND] ENCRYPT and DES [START/APPEND]
DECRYPT instructions. Instructions that do not conform to the following bit encodings are
unknown to the DES Channel that will go in error state.
DES instructions
There are 2 different DES instructions:
●
DES START
●
DES APPEND
The first instruction is used for setting the operation parameters, such as the key and the
initialization vector. The second one is used for passing the data to encrypt or decrypt.
DES START instruction
The DES START instruction can be applied with 2 different modes of operation:
●
ECB
●
CBC
ECB
The DES START ECB instruction is 2 words long. This instruction is used to set the key for
the following operations. The length of the key is encoded in the first instruction word, while
the second word represents the Source Address for the key.
