摘要
混沌序列具有容易生成、对初始条件敏感以及具备白噪声的统计特性等特点.讨论了一种以实数值混沌序列为基础,利用加密模板矩阵和排序变换,给出一种灰度图像的加密算法.分析表明:该加密算法不但具有较强的安全性,而且具有较快的加密速度.
Chaotic sequences have several good properties including the ease of their generation, their sensitive dependence on their initial condition and the statistic properties like flat noise. In this paper, a gray image encryption arithmetic based on chaotic sequences is proposed by taking advantage of the encryption template matrix and sort transformation. The results of analysis indicate that this encryption arithmetic is more secure and faster.
