ABSTRACT:
Multiple cipher hardware algorithms are run in parallel over an input stream. For example, one algorithm can process the input stream using an old cipher key while a parallel algorithm processes the input stream using the current cipher key. Alternatively, multiple cipher operations can be performed in parallel enabling a receiver to determine which cipher algorithm was employed in encrypting a data packet.
