SEC-CMAC A New Message Authentication Code Based on the Symmetrical Evolutionist Ciphering Algorithm

This article describes how the simplicity of data transmission made eavesdropping by malicious people easier. This became one the flaws of computer security that needs to be handled. In order to establish a secure data communication, many data security techniques were developed to ensure privacy, integrity and authenticity. One of the techniques developed was to fulfill authentication with a message authentication code (MAC) that was defined by the National Institute of Standards and Technology. It is still a powerful data integrity and authentication tool that provides better protection than error detection codes or checksums. In this article, the authors propose a new cipher-based message authentication code (CMAC) algorithm. Their proposed algorithm, termed SEC-CMAC, is based on a previously developed symmetric evolutionist ciphering algorithm named symmetrical evolutionist ciphering (SEC). Compared to the well-known previously developed MAC, their suggested algorithm proved to be robust and fulfill some security requirement by resisting an exhaustive key search and mac forgery attacks.
