MD5加密算法在当今已经被人们广泛的认识与应用 这里用java实现MD5加密代码-ECC C++

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
