摘要: 可信计算技术在提高系统安全性的同时,也给用户使用计算机带来了诸多限制。为了解决自由软件等未授权程序的可信验证问题,提出了一种基于可信计算的分布式可信验证机制(DTVMTC)。该机制以庞大的Internet用户群为基础,通过网络数据统计的方法,实现对应用程序的可信验证,从而解决了对无可信来源但实际可信的应用程序进行可信验证的问题,保障了用户使用可信计算平台的自由。在Windows平台实现了DTVMTC的原型,实验结果表明DTVMTC能够实现预定目标且具有良好的性能。

Abstract: Besides the improvement of the security of our system,Trusted Computing also contributes a lot of restricting for users.Aimed at resolving the problem of trusted verification of free software,a distributed trusted verification mechanism called DTVMTC on the strength of Trusted Computing is presented.Based on the huge amount of Internet users,this progress manages to verify the software’s reliability through the network data statistics,as a result of assuring the user’s using Trusted Computing Platform at one’s own discretion by verifying the application with no trusted source.Finally,a prototype of DTVMTC is presented and this in return indicates the outstanding performance of DTVMTC in achieving targets in advance.

Key words: trusted computing, transitive trust, application verification, trusted verification, distributed trusted verification
