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

一个ASP的SHA256加密算法-an ASP SHA256 encryption algorithm

此代码提供关键时间表中的数据加密标准 (DES)，这是生成子密钥的算法的实现的。 • 输入： （长度 （64 位） 的任何字符串。 • 输出： 16 子键产生的 DES （每个 48 位长度）。 如何使用它： 1.>> K = DES_KeyScheduling %会创建一个类 "DES_KeyScheduling" 的对象。 2.>> K.KEY_STRING = "密码" %设置的加密密钥值。 3.>> K.printPC2() %打印输出的置换选择 2 （PC-2） （也称为 x 16 48 及其子键） 无压痕。用来调用函数 1 "K.printPC2(1)" 要输出带缩进值。
