A Multi-Level Security Model Based on Trusted Computing

Some secure models protect the confidentiality and some secure models protect the integrity. How to combine the two types secure models faultlessly is still a problem. At present, a serious of secure models protect both confidentiality and integrity are based on the privilege subject, but it does not satisfy the least privilege principle. In the paper, a multi-level security model based on trusted computing is proposed, and it can limit the privilege of subjects efficiently. Key words: multi-level security model, trusted computing, confidential level, integrity level, trusted subject, the least privilege
