  • Patent number: 8374343
    Abstract: A system for executing a symmetric key cryptographic method includes a processor selecting data paths, a key, an initialization vector, a memory storing batched operation parameters, a bus connected to the processor and the memory, a cryptographic processor connected to the bus and controlled by the processor for performing a plurality of operations according to the operations parameter, wherein data for each operation is received individually and separately from the batched operation parameters, wherein an output for each operation is transmitted separately, and a pair of first-in-first-out (FIFO) state machines controlled by the processor and selectably connected to one of the cryptographic processor and the bus, bypassing the cryptographic processor.

  • Patent number: 7831040
    Abstract: A symmetric key cryptographic method is provided for short operations. The method includes batching a plurality of operation parameters (1503), and performing an operation according to a corresponding operation parameter (1505). The symmetric key cryptographic method is a Data Encryption Standard (DES) method. The short operations can be less than about 80 bytes. The short operations can be between 8 and 80 bytes. The method includes reading the batched parameters from a dynamic random access memory (1504), and transmitting each operation through a DES engine according to the operations parameter (1505).
