Design and Implementation of SMS4 Encrypted Communication on Chip Based on the Programmable System

针对面向工业用、商用以及民用电子设备加密串行通信需求,通过基于SMS4的加密通信SOPC软硬件架构、SMS4加密通信控制器IP技术、SMS4加密通信软件技术等内容的研究,实现了基于SMS4加密算法的串行通信技术,并在非128位明文的加密传输数据控制和基于8位异步模式的128位数据串行收发上效率明显提升。基于SMS4的加密通信SOPC提高了系统的加密通信功能可定制能力,且使加密通信核心算法自主可控。

This paper is intended for industrial, commercial and consumer electronic device encryption on seri- al 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 ad- vanced. The encrypted communications SOPC based on SMS4 improves the encrypted communication capabilities with independent and controllable encrypted communication core algorithm.
