The high speed block cipher-based message authentication code algorithms are required for different networking applications. This paper presents the Cross Message Authentication Code based on Multi-core computing technology (CMMAC), which is a parallel block cipher working mode on multi-core computing environment and secure for messages with any bit length. In CMMAC mode, the large file is divided into a number of blocks that are encrypted based on a symmetric key block cipher, keeping the relation among blocks by message cross transfer among processing cores. The algorithm analysis and experiment result indicates this method is expandable and obtains linear speedup.
