MD5 算法描述 对 MD5 算法简要的叙述可以为：MD5 以 512 位分组来处理输入的信 息，且每一分组又被划分为 16 个 32 位子分组，经过了一系列的处理后， 算法的输出由四个 32 位分组组成， 将这四个 32 位分组级联后将生成一个 128 位散列值。 在 MD5 算法中，首先需要对信息进行填充，使其字节长度对 512 求 余的结果等于 448。因此，信息的字节长度（Bits Length）将被扩展至 N*512+448，即 N*64+56 个字节（Bytes） ，N 为一个正整数。填充的方 法如下，在信息的后面填充一个 1 和无数个 0，直到满足上面的条件时才 停止用 0 对信息的填充。 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

ieee一种基于混沌的新加密方法An Image Encryption Scheme Based on Chaotic Map - In this paper, a novel block digital image encryp- tion scheme based on a chaotic coupled map lattices (CML) is reported. Within this scheme, an original image is decomposed into sub-blocks with a given size, and an external secret key with 192-bit is used and mapped to the system parameters, which are employed to generate a spatiotemporal chaotic binary sequence matrix to encrypt the block original image. Besides, the former sub-block encrypted result will be acted as a feedback to the following sub-block encryption proc- ess. The proposed scheme is described in detail, along with the security analyses such as key space analysis, sensitivity analysis, information entropy analysis and correlation coefficients analysis of adjacent pixels. The computer simulation results indicate that the suggested image encryption scheme has some properties desir- able in a good security
