基于TPM仿真器的可信计算实验平台设计

Design of Trusted Computing Experimental Platform Based on TPM_emulator

传统的可信计算实验平台需要实际硬件电路支持,给理论研究和应用程序开发带来不便。由于可信计算协议层和应用层不涉及具体硬件,因此设计了一种可信计算仿真实验环境,该环境主要借助TPM_emulator和TrouSerS实现,完全不依赖硬件,函数接口与真实的可信计算平台完全兼容。重点介绍了仿真软件的编译安装方法以及TDDL和TSPI两种可信计算编程接口,并对TPM仿真环境进行了测试,验证了仿真实验平台的可行性和便捷性。

Traditional trusted computing experimental platform brings inconvenience to the theoretical research and application development for it needs the support of actual circuit board. As Protocol layer and application layer of the Trusted Computing do not involve specific hardware, a trusted computing simulation environment by using TPM _emulator and TrouSerS is designed, which is completely dependent on software simulation, and its programming interface is fully compatible with real trusted computing platform. The paper focuses on the compilation process and usage method of simulation software packages, especially two important trusted computing call interfaces ： TDDL and TSPI. The tests of TPM simulation environment fully proved the feasibility and convenience of the simulation platform.
