It will affect national’s future and the development directly. Various countries all regarding this as important technology.With the rapid development of internet, people pay more attention to the information security. DES (Data Encryption Standard) encryption arithmetic has been standing through many tests since it became the encryption standard. It is proved that the security of the DES encryption can satisfy the voluminous needs. Therefore, the main contributions of the paper are as follow: (1)Completed the whole design of the DES encryption system .The whole system includes the DES encryption core module and the function package module. (2)Used ALTERA Company platform--Quartus II，VHDL to realize design , compile, and simulate the design.
