摘要

传统的可信计算主要以板卡、芯片等形式实现,对硬件改造的要求极大地限制了可信计算的广泛应用。为应对这一困境,随着 CPU 内置安全模块的发展,设计 "芯片上的可信计算 "成为一种趋势。主要的挑战在于如何充分利用处理器的安全特性,设计出符合可信计算 3.0 要求的双计算安全系统。目前,Phytium 和 Loongson 等处理器的内置安全和加密单元以及支持的可信执行环境已经为内生可信计算奠定了基础。本文提出了 TeTPCM:基于 TEE 的内生可信平台控制模块 (TPCM),通过 TEE 与 phytium 处理器上的 SoC 协同工作,构建内生可信计算架构。实验分析表明,与通用可信计算芯片相比,内生可信TPCM无需额外硬件,具有能力强、性能高、可扩展性好等特点,具有更好的应用前景。

TeTPCM: building endogenous trusted computing on trusted execution environment
Traditional Trusted Computing is mainly implemented in the form of boards, chips, etc., and the requirements of hardware modification have greatly limited the widely use of trusted computing. To cope with the dilemma, the idea of designing “Trusted Computing on Chips” becomes a trend with the development of the build-in security module in CPUs. The main challenge lies on how to make full use of processor security features and design a dual-computing security system that meets the requirements of Trusted Computing 3.0. At present, the built-in secure and cryptographic units on processors, such as Phytium and Loongson, and the supported Trust Execution Environment have already provided the foundation for endogenous trusted computing. In this paper, we propose TeTPCM: a TEE Based Endogenous Trusted Platform Control Module (TPCM), which builds an endogenous trusted computing architecture by the collaboration of the TEE and the SoC on phytium processor. Experimental analysis shows that compared with the general-purpose trusted computing chip, endogenous trusted TPCM does not need additional hardware, and is characterized by strong capability, high performance, good scalability, and has better application prospects.
