基于无剑100 SoC的双核TEE安全系统构建

A Dual-Core TEE Safety System Based on the Wujian 100 SoC

现代社会中信息和数据的重要性越来越高,信息安全问题越来越引起重视。基于无剑100 SoC构建一个双核的TEE安全系统,在无剑100原有架构中添加一个处理器核,并实例化新的存储和串口,修改总线仲裁规则和地址映射,实现内存隔离和串口隔离。将系统移植到FPGA开发板上进行测试和验证。改造后的双核TEE安全系统能够在FPGA开发板上正常运行,并且能够独立运行TEE核和REE核的程序。此外,它还能够通过不同的串口进行通信,使得用户可以成功地获取程序的输出结果。这一结果表明,该安全系统在硬件和软件方面都表现良好,能够有效地保护计算机系统和数据的安全。

In modern society,the importance of information and data is increasing,and information security issues are receiving more and more attention.Based on Wujian 100 Soc,a dual-core TEE security system is built.An additional processor core is added to the original Wujian 100 architecture,and new storage and serial ports are instantiated.The bus arbitration rules and address mapping are modified to achieve memory isolation and serial port isolation.The system is transplanted to an FPGA board for testing and validation.The refurbished dual-core TEE security system can work normally on the FPGA board and can independently run programs on the TEE core and REE core.In addition,it can also communicate through different serial ports,allowing the user to successfully obtain the output results of the program.This indicates that the security system performs well in both hardware and software aspects,effectively protecting computer systems and data security.
