ABSTRACT:
An apparatus and method for implementing a block cipher algorithm. In one embodiment, a cryptographic unit configured to implement a block cipher algorithm may include state storage configured to store cipher state, where the cipher state includes a plurality of rows and a plurality of columns. The cryptographic unit may further include a cipher pipeline comprising a plurality of pipeline stages, where each pipeline stage is configured to perform a corresponding step of the block cipher algorithm on the cipher state, and where a given one of the pipeline stages is configured to concurrently process fewer than all of the columns of the cipher state.
