Abstract

The invention discloses a software trustworthiness engineering method based on a formalized and unified software model, belonging to the field of software trustworthiness. The method comprises the following steps: building an unified software model which includes software requirement design information, software implementation information and runtime environment information based on a formalized language and a traditional UML (unified modeling language) view; carrying out the consistency and validity verification of the unified software model according to the software trustworthiness engineering technical architecture and automatically generating an unit test case; building a software security defect knowledge base based on the unified software model; finding out potential software security defects in the unified software model based on the software security defect knowledge base by a formalized language theorem proving machine; and giving out a corresponding alleviating solution according to the potential software security defect. The software trustworthiness engineering method has the beneficial effects of improving the software quality, eliminating the design defect, reducing the development cost, enhancing the maintainability and the like and solves the problems in the traditional software engineering.

Description

technical field [0001] The invention takes the credible software development process as the main object, builds a software engineering theoretical system combined with formal methods, improves the non-formal essential deficiencies of existing software engineering, and introduces a defect detection mechanism to detect and alleviate in the software design stage Defects belong to the field of software trustworthiness, and in particular relate to a software trustworthiness engineering method based on a formalized and unified software model. Background technique [0002] With the continuous development of computer applications, it plays a vital role in the information society. But the current situation of software production is not satisfactory, and software safety accidents, software quality problems and software expansion problems have brought huge losses. Experts and industry giants at home and abroad have regarded the credibility of software as an important attribute of soft...
