In this paper, a novel parallel block cipher operation mode for Multi-core Message Authentication Code (MMAC) is proposed to improve the speed of generating authentication code by each processing core to handle a part of blocks. Then the Multi-core MAC generation algorithm (GMMAC) is presented in which the message of any bit length is divided into a number of blocks that are encrypted based on Advanced Encryption Standard (AES), keeping the relation among all blocks inter-cores and extra-cores. The algorithm analysis and experiment indicates this method is expandable and near linear speedup.
