<p>An encryption and decryption processing method of achieving SMS4 cryptographic algorithm and a system thereof are disclosed. Firstly, the method prepares constant arrays, inputs the external data into a data registering unit and deals with the first data conversion; secondly, deals with the second data conversion; thirdly, repeats the second data conversion, until completing all the prescribed data conversion, and then achieving the results of repeating encryption and decryption processing.</p> |
