Abstract:

This paper is intended for industrial,commercial and consumer electronic device encryption on serial communication.SMS4 algorithm for serial communication on hardware optimization techniques are designed and implemented based on the research into the SOPC hardware and software architecture,controller IP technology,and software technology of the SMS4 encrypted communication.Non-128 plaintext encrypted transmission data control technology and 128 bits transceiver technology based on eight asynchronous serial data pattern have been greatly advanced.The encrypted communications SOPC based on SMS4 improves the encrypted communication capabilities with independent and controllable encrypted communication core algorithm.

Key words: serial communication;SMS4;encryption communication;system on chip
