Research On Trusted Technology Of Software Behavior

In the trusted computing research, trust is established based on trustmeasurement and trust delivery. To ensure that the system is trusted, the trust ofsystem should be measured. The basic method of trust measurement is verifying theintegrity of the system resources, but this method can only be sure that the computersystem static resource integrity before startup phase, It can’t guarantee the trusted ofsoftware’s behavior in running system. To ensure system is trusted, it must beguaranteed the system is trusted in all phase. The problems of software behaviortrusted in running system have become a key issue in the trusted computing study. Atpresent, trusted of software behavior is not strictly defined. And there are norecognized measurement methods of software behavior trusted in academia.Based on Trusted Computing concepts and basic ideas, combined with thedefinition and properties of trust, the understanding of trust is given. The mainproblem of the research in the field of software trusted is analyzed. According to theproblems of expected behavior construction in current research, the understanding ofsoftware behavior trusted is given. Elements of software behavior trusted and themethod of expected behavior construction are proposed. Definition, purpose,properties and application scenarios of trusted behavior declaration are given.Based on the Systems Development Life Cycle, trusted behavior declaration isdivided into some phases. The roles about trusted behavior declaration are discussed.Based on the definition of trusted behavior declaration and the elements of softwarebehavior trusted, the declaration of trusted behavior is designed. The description ofsoftware Information, declaration information and behavior information in trustedbehavior declaration are designed. The description methods and researching range ofsoftware behavior’s subject, object, action and other elements are determined. And aXML document structure of trusted behavior declaration is given.Basic measure scheme of software behavior trusted base on trusted behaviordeclaration was proposed. The design phase, validation phase, publishing phase,deployment phase, configuration phase and access phase of trusted behaviordeclaration is detailed designed, and the key strategy is given.Based on the comparison experiments of software behavior, completeness,necessity, intelligibility of trusted behavior declaration is analyzed. Based on the construction experiment of trusted behavior declaration, the construction feasibilityand availability of trusted behavior declaration are verified.
