A5加密算法

ElGamal算法不仅用于数据加密也能用于数字签名，其安全性依赖于有限域上离散对数问题的计算。该方法的关键。首先，选择一个素数P，两个随机数，G和G，X，X＜P，计算Y = G ^ X（MOD P），其公钥Y，G和P的私钥X G和P的一组用户共享。ElGamal数字签名。信息签署M，先选择一个

C++写的md5算法实现，喜欢的拿去吧，哈哈~-Writing C++ implementation of md5 algorithm, like take it, haha ~

使用迭代方程Xn+1=Asin2(Xn-XB)生成混沌序列{Xi}，需输入A和Xb值，不同的值产生不同的加密效果，但是仅在混沌区内的加密效果最好。在Microsoft Visual Studio .NET 2003上调试成功，用C++语言编写-use an iterative equation Xn Asin2 = (Xn- XB) generated chaotic sequence (Xi) need input A and isolate value, different values in different encryption effect, but only in the chaotic region of encryption is the best. In Microsoft Visual Studio.NET 2003 Debugger success C Language

EXE二合一源代码!不用多说了!用tasm编译!-source code! Needless to say! With Tasm compiler!

这是RC5算法的ASM实现，效率很高，可以直接用到工程中去-This is the RC5 algorithm ASM realization of very efficient and can be used directly on projects to

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
