  Abstract

At present, the research on software trustworthiness mainly focuses on two parts: behavioral trustworthiness and trusted computing. The research status of trusted computing is in the stage of active immune of trusted 3.0. Behavioral trustworthiness mainly focuses on the detection and monitoring of software behavior trajectory. Abnormal behaviors are found through scene and hierarchical monitoring program call sequence, Restrict sensitive and dangerous software behavior.

At present, the research of behavior trust mainly uses XML language to configure behavior statement, which constrains sensitive and dangerous software behaviors. These researches are mainly applied to software trust testing methods. The research of XML behavior statement file mainly uses the method of obtaining sensitive behavior set and defining behavior path to manually configure. It mainly focuses on the formulation of behavior statements and the generation of behavior statement test cases. There are few researches on behavior semantics trustworthiness. Behavior statements are all based on behavior set configuration XML format declaration files. There are complicated and time-consuming problems in manual configuration, including incomplete behavior sets. This paper uses the trusted tool of semantic analysis technology to solve the problem of behavior set integrity And can generate credible statement file efficiently.

The main idea of this paper is to use semantic analysis technology to model requirements, including dynamic semantic analysis and static semantic analysis. This paper uses UML model to automatically generate XML language code, behavioral semantic analysis and modeling, and formal modeling of non functional requirements, so as to ensure the credibility of the developed software trusted tools and the automatically generated XML files. It is mainly based on the formal construction of non functional requirements Model research, semantic analysis of the state diagram and function layer in the research process, generation of XML language trusted behavior declaration file by activity diagram established by model driven method, and finally generation of functional semantic set and functional semantic tree set by semantic analysis to ensure the integrity of the software. Behavior set generates behavior declaration file in XML format by the design of trusted tools Trusted computing is used to verify the credibility of trusted tools.
