  • Methods and apparatus for implementing a cryptography engine
    Patent number: 7555121
    Abstract: Methods and apparatus are provided for implementing a cryptography engine for cryptography processing. A variety of techniques are described. A cryptography engine such as a DES engine running at a clock frequency higher than that of surrounding logic can be synchronized with the surrounding logic using a frequency synchronizer. Sbox logic output can be more efficiently determined by intelligently arranging Sbox input.
