数据加密算法，凯撒，普雷费尔
零数据加密算法（数据加密算法，DEA）是对称加密算法，可能是最广泛使用的密钥系统，特别是在金融数据的安全性，最初开发的DEA是嵌入在硬件中。一般情况下，ATM（自动取款机，ATM）使用DEA。它出自IBM的研究工作，IBM有它的专利数年，但1983年以后已经过期，在公共范围，允许在特定条件和使用情况下免除专利使用费。 1997年正式通过了美国政府。DES原来的思路可以参考一下二战中德国的Enigma机，大约相同的基本思想。传统的密码加密都是由古代的观念，从循环移位，谜机器是基于扩散模糊。但原则的本质是相同的。现代DES在二进制级别做着同样的事：替代模糊，增加了分析的难度

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
