可信执行环境 (TEE) 是机密计算的主要推动者。本文介绍了工业界和学术界现有可信执行环境的系统化。我们重点介绍这些 TEE 用于提供不同安全保证的通用机制，并对不同 TEE 提案进行详细的比较分析。 TEE 预计将成为应对高性能计算 (HPC) 领域安全挑战的有前景的解决方案。然而，本文说明了为什么现有的 TEE 不适合高性能计算系统。最后，我们呼吁采取行动，随着不断发展的高性能计算环境来发展 TEE 技术。
Trusted execution environments (TEEs) are primary enablers of confidential computing. This paper presents a systematization of the existing trusted execution environments in industry and academia. We highlight the common mechanisms these TEEs employ to provide different security guarantees and offer a detailed comparative analysis of different TEE proposals. TEEs are anticipated to be a promising solution for the security challenges in the high-performance computing (HPC) domain. However, this paper shows why the existing TEEs are unsuitable for high-performance computing systems. Finally, we present our call for action to work to evolve the TEE technologies with the evolving high-performance computing landscape.
