Abstract

In this paper, a new switching parameter varying optoelectronic delayed feedback model is proposed and analyzed by computer simulation. This model is switching between two parameter varying optoelectronic delayed feedback models based on chaotic pseudorandom sequences. Complexity performance results show that this model has a high complexity compared to the original model. Furthermore, this model can conceal the time delay effectively against the auto-correlation function, delayed mutual information and permutation information analysis methods, and can extent the key space, which greatly improve its security.

摘要

本文提出了一种新型的切换参数变化光电延迟反馈模型，并通过计算机仿真进行了分析。该模型基于混沌伪随机序列在两个参数变化光电延迟反馈模型之间进行切换。复杂度性能结果表明，与原模型相比，该模型具有较高的复杂度。此外，该模型针对自相关函数、延迟互信息和排列信息分析方法能够有效隐藏时间延迟，并且能够扩展密钥空间，大大提高了其安全性。
