基于能力系統(tǒng)的應(yīng)用證明研究

通過對可信計(jì)算及其主要功能“遠(yuǎn)端證明”的分析，提出“應(yīng)用證明”的概念及原理，并說明支持應(yīng)用證明所需的安全機(jī)制。分析現(xiàn)有主流操作系統(tǒng)所使用的保護(hù)結(jié)構(gòu)和訪問控制模型，說明應(yīng)用證明在當(dāng)前的主流操作系統(tǒng)上是無法實(shí)現(xiàn)的。通過對能力系統(tǒng)EROS 進(jìn)行改進(jìn)，使其充分支持應(yīng)用證明，并提高系統(tǒng)的安全性及可信性。

Abstract: Through the analysis of the trusted computing and its main function remote attestation, the paper roposes the concept and principle of application attestation, and explains the security echanism that needs to upport application attestation. The paper analyses the protection frame and the access control model of the ainstream operating system, and points out that it is impossible to implement application attestation on the
mainstream operating system. Through the modification of the capability system EROS, the modified EROS can ell support the application attestation and improve the system’s security and trusting degree.
Keywords: trusted computing; remote attestation; application attestation; capability system
