| Abstract: | Encryption algorithm standard has been widely used in the software encryption and hardware encryption for a long time.It will be of great significance to research and analyze the principles and characteristics of DES encrypted algorithm in promoting the development of modern cryptography.Based on the study of DES,through S-DES algorithm model,this paper illustrates the encrypted principles of DES,and the characteristics of S-box that S-box is not unique,and S-box input modes are not unique,etc. |
