## 数据加密标准AES算法的实例分解演示

Data encryption standard AES algorithm decomposition demonstrated
Abstract:     With the rapid development of computer data communications services,users on the network security performance demand is higher and higher,DES has been unable to meet the requirements.The plans of the AES is the U.S.national institute of standards and technology,intend to replace corn-based ethanol.As a replacement for traditional symmetric encryption standard DES algorithm is safer ,cheaper,small and more flexible.Because of DES with the development of the computer has been unable to meet the needs of people,so this system specifically for the decomposition of AES for the decomposition of AES for instance animation demo。The system operation simple easy to understand,let the study of this course students can better understand the process of AES encryption.More conducive to the vivid display of the ideas of teachers in the process of teaching. 源￥自%六^^维*论-文+网=www.lwfree.cn
