| 摘 要： | 在混沌系统中施加主动扰动是混沌从理论研究向实际应用转化的有效手段。本文利用混沌映射作为扰动信号实现有限精度的混沌序列。扰动后的系统服从均匀分布，具有更为理想的扩散特性和置乱特性。仿真结果表明了该方案的可行性。

| Abstract: | A concept of perturbing the values of variables in digital chaotic system is studied. In this paper, an approach to realize finite precision chaotic systems via perturbation of chaotic sequences is presented. After being perturbed, chaotic system can generate chaotic binary sequences with uniform distribution and with statistic properties invulnerable to cryptographic analysis. The simulation result shows that the perturbing concept is feasible. |
