摘要
利用Logistic混沌系统生成混沌序列,给出一种二值序列的生成方法,然后对其性能进行了分析,并和其他方法进行了比较。实验表明这种方法生成的二值序列具有很好的伪随机性以及相关性。把这种方法产生的二值序列用在图像加密中,得到了较好的结果。
A new approach for generating binary chaotic sequences based on Logistic chaotic systems was proposed,and the performances of these binary sequences were analyzed.The proposed algorithm was compared with others as well.The results show that the generating bi-nary sequences have good pseudo—randomness and correlation.The binary sequences were also applied to image encryption and good re-sults were achieved.
