With the development of computer technology and network application, the safety of application has become one of the most important research problems in the field of information security. Firstly, the paper analyzes malicious attack approaches for applications. Secondly, this article proposes an application anti-attack model (AAM), and further presents the formal description of the model. Finally, this paper represents its good security properties and proves them.

This paper proposes a security paradigm named self-trusted access control. The paradigm brought forward here is absolute different from others. It gives the computer user more power and more confidence with computing, which is specially called self-trusted access control. Its realization structure consists of hidden sensitivity label, mandatory access control and user setting. All of its components are mainly constructed on hardware level with no cooperation of OS, which makes it to be free of any kinds of software attacks. That is to say, it has a unique structure to assure that computing is trusted for the user, because user’s intentions are faithfully executed. This paper describes its principle and shows the accomplishment of such control on general computer architecture. As described, such security paradigm can make trusted computing indeed trustworthy to computer user.
