摘要

With great demand for digital signal transmission and big losses incurred from illegal data access, signal security has become an extremely critical issue. In this paper, a new signal security system, along with its VLSI architecture, is proposed. Based on the simple idea of overturning dominoes, each signal value is randomly transformed according to a binary sequence generated from a chaotic system, and therefore, a completely disordered signal can be obtained. The features of the system are as follows: 1) no distortion, 2) high security, and 3) suitability for system integration. In order to implement the system, its VLSI architecture is designed with low hardware complexity and high computing speed. Moreover, the FPGA realization results indicate that the data processing rate of the proposed design achieves 800 Mbps, fast enough for MPEG2 in HDTV applications. Finally, the simulation and comparison results are given to demonstrate the proposed system's effectiveness.
