In this paper, we propose a dedicated keyed hash algorithm based on the modified coupled chaotic map lattice. By using the nearest and long distance couplings, both the key and the message as the parameters of the coupled map lattice, the expansion key and the nonlinear transformation, the system has enough confusion and diffusion rate between the message and the key. The structure of the system provides strong collision resistance and high performance efficiency. Simulation results show that the system has a uniform and random distribution of hash value, and fast performance.
