| titleOfInvention | Methods and apparatus for implementing a cryptography engine |
| abstract | Methods and apparatus are provided for implementing a cryptographynengine for cryptography processing. A variety of techniques are described. Ancryptography engine such as a DES engine can be decoupled from surrounding logicnby using asynchronous buffers. Bit-sliced design can be implemented by movingnexpansion and permutation logic out of the timing critical data path. An XORnfunction can be decomposed into functions that can be implemented morenefficiently. A two-level multiplexer can be used to preserve a clock cycle duringncryptography processing. Key scheduling can be pipelined to allow efficient roundnkey generation. |
