Fast software implementation of AES-CCM on multiprocessors

Abstract

This paper presents a novel software implementation of AES-CCM (Advanced Encryption Standard-Counter mode with Cipher Block Chaining Message Authentication Code) for multiprocessors. The software includes AES key expansion for dual multiprocessors and cipher/inverse cipher for dual/quad multiprocessors. On the measurement of a Xilinx MicroBlaze multiprocessor based platform, the speedup of our AES key expansion, cipher and inverse cipher is up to 1.7, 2.6 and 2.6 times, respectively. Using the new software implementation of AES, AES-CCM for IEEE 802.11i is implemented on the octet MicroBlaze processors. The fast software implementation of the AESCCM for multi processors is up to 3.6 times faster than the implementation for the single processor. © 2011 Springer-Verlag.
