Past exam questions

The hardware-security handout that the guest lecturer, Dr Kuhn, gave out on 28 October is here.

It was pointed out after the 16/11/04 lecture that I'd an error in the Skipjack diagram on my slide. In the type B round, there should be a wire from the output of W1 to the XOR. The correct diagram can be found at the NIST website, which has the official specifications of AES, DES and Skipjack.
