摘要
基于分段线性映射 (PLM)的多次迭代反馈混沌流密码体制需要多次迭代而且实时性较差和相图中存在局部线性结构的缺点 ,提出了非线性耦合反馈的改进方案 .理论分析和仿真实验表明 ,该方案在保留原有体制所具有的优良密码学特性的同时 。
This paper presented a scheme to improve the real time performance and local complexity of the chaotic stream cipher based on piecewise linear maps. Both the theoretic analysis and the results of simulation show that this scheme greatly decreases the time consumed by multi iteration and improve the micro strcuture of the phase space graph on condition that the good properties of the original scheme are remained.
