two-path feedback

Using a simple chaotic system and another chaotic system based on linear system with a piecewise linear state feedback, we put the two sequences through threshold function and XOR operation. The result we get is an unpredictable pseudo-random sequence.

通过把简单混沌系统与线性系统、分段线性状态反馈函数所形成的混沌系统在阈值化后进行异或运算，使得输出的密钥流为不可预测性的伪随机序列。
