摘要

In this paper, we propose a robust hyper-chaotic system that is suitable for digital secure-communication. The system consists of many coupled robust logistic maps that form a hyper-chaotic system. It has a higher degree of complexity than traditional discrete-time secure-communication systems that use only a single map. Moreover, the system has a very large parameter space which grows along with system precision. Hence, attacking the system by the method of map reconstruction in current computation technology is not feasible. Statistical analysis shows that the system achieves very high security level. Finally, two hardware architectures (multiple-cycle and pipelined) are proposed for area and performance optimization, respectively.
