A Scheme Based on Trusted Computing for Terminal Security

According to the current security problems of computer terminal and trusted computing goals proposed by Microsoft Corporation, this paper proposes a solution scheme based on trusted computing for terminal security. By means of formal method, it gives some rules to control user´s access to program and data based on its level. Legal programs only can run authorized operation and data file protected by cryptogram based on its level avoiding information leakage. A frame to realize the scheme is also given. And this scheme is described from security and privacy two facets.
