GENERATOR FOR GENERATING A MESSAGE AUTHENTICATION CODE, METHOD OF GENERATING A MESSAGE AUTHENTICATION CODE, PROGRAM ELEMENT AND COMPUTER-READABLE MEDIUM

摘要

Current MAC algorithms impose a significant system performance requirement in order to process messages in real time. According to an exemplary embodiment of the present invention, a hardware implemented generator for generating a MAC is provided, that results in a significant improvement in hardware performance requirements for processing messages in real time. The engine is based on linear feedback shift registers which are adapted to generate secure MACs.
