| 摘 要： | 利用了混沌系统对初始条件敏感依赖性及混沌轨道的遍历性与非周期性，同时利用了二维映射的参教空间和相间比一维映射大的优点，构造了一种基于二维Logistic映射的加密算法，并将其应用在数字图像的加密上。通过对计算机模拟试验的结果进行分析证实，该加密方法具有较好的加密性能。

| Abstract: | A new block encryption algorithm was presented, which is based on the Coupled Logistic chaotic map using the sensitive dependence, ergodieity, nonperiodicity and also using the larger parameter space and the phase space. Then it was applied to the encryption of images. Conclusion from computer simulation results verifies that the encryption algorithm has better encryption characteristics. |
