ABSTRACT:
A method and system for pipelined decryption is disclosed. One embodiment includes a circuit having an iterative calculation section and a cipher text storage section in support of cipher block chaining (CBC) encryption mode. The iterative calculation section may be pipelined and configured to process multiple ciphertexts at once for increased throughput.
