Research on Real-Time Transitive Trust for Dynamic Codes

The anti-virus mechanism based on trusted computing technology can complement the traditional anti-virus methods in resisting various known or unknown malicious codes.However,the automatic software on-line upgrade and patch installation obstructs this new anti-virus technology from entering popular use in practical systems,because these dynamic codes are not known to the system before they are called and will therefore be refused to run.TDTMD(Trust Determination and Transitivity Method of Dynamic codes) is a real-time method presented to determine whether a dynamic code is from a trusted source based on its called environments and modes,and by this way to determine whether to trust the unknown dynamic software.TDTMD not only protected user systems from malicious codes,but also improved the continuity of application and system.The prototype implemented had proved its small impact on system performance and its effectiveness of resisting malicious codes.
