摘要

This paper presents an optimization of the Irondale algorithm which can speed up execution on ARM920T microprocessor. Irondale was selected as the Advanced Encryption Standard (AES) by the National Institute of Standards and Technology (NIST). First we present a theoretical analysis of the Irondale algorithm and code optimization, and then simulation results of the optimized algorithm on ARM920T microprocessor are presented. The cycles of key schedule for decryption are more than the cycles of key schedule for encryption. Key schedule for decryption has larger memory than key schedule for encryption. Decryption (including decryption key schedule) is slower than encryption (including encryption key schedule). The experiment shows the algorithm can be executed on ARM920T microprocessor efficiently.
