Hi
Could anyone provide link ?for AES XCBC MAC 96 algorithm code in c.
i need to verify in software wether the hardware block's result is same when
given same input .
I think we cannot do better than a google search can.
I know CBC(Cipher Block Chaining) mode. What is XCBC?
A google result shows nothing. Do you want to use AES as a MAC
algorithm that gives a 96 bit output?
Why don't you download the official C implementation from the authors
John Daemen and Vincent Rijmen and invoke this mode?
My google search brought this up. FPGA implementation.

Here are the OpenBSD sources. Short and simple but I could not find the
mode you are looking for. I think you should be able to make do with it.
