DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。DES算法以被应用于许多需要安全加密的场合。（如：UNIX的密码算法就是以DES算法为基础的）。-DES (Data Encryption Standard) algorithm, in 1977 the United States government"s official permission, is a key 56 to 64-bit data encryption methods. DES algorithm to be applied to many needs security encryption occasions. (Eg : UNIX password algorithm is to DES algorithm-based).

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
