Abstract

A data processing system includes a cryptographic processing module providing for cryptographic key generation. A method entails computing derived keys one time, during a first execution of a key generation process, such that they may subsequently be utilized for processing large quantities of data without being re-computed. The derived keys provide for the efficient cryptographic processing of data, including data frames.
