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).
