首发时间:2013-08-15
摘要:在权限管理系统中构建一个可信的策略文件完整性验证系统是保证系统安全的关键之一。普通PC环境下的策略文件可能被恶意篡改,无法有效保证其唯一性。本文基于TCM,并结合UKey对文件的安全性存储技术,设计了可信环境之下的文件完整性验证方案,并对一个以文档形式存储的设备权限文件为例,对方案的实现进行了具体说明。

The Integrity Verification of Policy Documents Based on TCM and UKey
Abstract:Building a credible policy file integrity verification system is one of the keys to ensure system security in the rights management system . Ordinary PC environment policy files might be malicious distorted and can not effectively guarantee their uniqueness. In this paper, a file integrity verification program with the trusted environment was designed, which was Based on TCM and the UKey security storage technology. A file integrity verification system of a USB device policy file was set up as an example of the program with detailed process .
Keywords: trusted cryptography module(TCM) USB Key(UKey) file integrity verification
