Summary:
It may be difficult for traditional chaining type Message Authentication Code (MAC) to work efficiently in parallel computing environment. In this paper, a chaos-based non-chaining MAC for parallel realization is proposed, whose structure can ensure the uniform sensitivity of MAC value to the message. By means of the mechanism of both changeable-parameter and self-synchronization, the keystream establishes a close relation with the algorithm key, the content and the order of each message block. The entire message is modulated into the chaotic iteration orbit, and the coarse-graining trajectory is extracted as the MAC value. Theoretical analysis and computer simulation indicate that the proposed algorithm can satisfy the performance requirements of MAC. It is a good choice for MAC on parallel computing platform.
