Abstract:
An encryption and decryption processing method, system and computer-accessible medium for achieving SMS4 cryptographic procedure/algorithm can be provided. First, constant arrays can prepared, the external data are input into a data registering unit and the first data conversion is addressed. Secondly, the second data conversion is addressed. Thirdly, the second data conversion is repeated until completing all the prescribed data conversion. Then, the results of repeating encryption and decryption processing are achieved.
