Problems solved by technology

The traditional model encounters an important challenge when it is applied to the credibility evaluation: after the model is submitted for operation, based on the basic evaluation information collected in a steady-state environment, the quantitative credibility evaluation of the software can be obtained, but the credibility of the software The trustworthy requirement (TR) still has dynamic evolution: the same user has different trustworthy requirements in different environments and different states (periods), and the traditional static model does not have dynamic adaptive features, so it cannot solve the evolution of trusted requirements software credibility assessment

Embodiment Construction

[0092] The invention mainly provides a reliability dynamic evaluation method oriented to software evolution. Based on the analysis of the existing credible software evaluation requirements, this method comprehensively considers the failure of the credibility evaluation index system in the process of software evolution and the inability to carry out credible evidence reasoning normally, and designs and implements the reliability evaluation index based on the correlation matrix. System Adaptive Reconfigurator, and on this basis, a dynamic evaluation method of credibility oriented to software evolution is given, which is mainly divided into seven steps: first, follow the overall goal of complex system software credibility assessment, Based on the reasoning logic and calculation process of uncertain software credibility assessment, a software credibility assessment process oriented to software evolution is defined; secondly, combined with domain expert knowledge, the relevant techn...

Abstract

The invention discloses a trustworthiness dynamic evaluation method facing software evolution. Based on the existing evaluation requirements of the trusted software, and by comprehensively considering the problems that a trustworthiness evaluation index system (TEIS) fails, trustworthiness evidence reasoning can not be developed normally and the like, a self-adaptive reconfiguration unit is designed to implement the TEIS based on associated matrix.. The research and application of the invention provide a convenient and effective solution for the problem of the trustworthiness dynamic evaluation under the background of software evolution, overcome the disadvantages of the conventional models in the aspects of dynamic nature, universality and uncertainty, and ensure the significant value in practical use.

Description

technical field [0001] The invention relates to the field of software engineering, in particular to the field of software credibility evaluation, in particular to a method for dynamic evaluation of the credibility of software evolution. Background technique [0002] Software credibility refers to the evaluation of whether all non-functional attributes (also called trusted attributes) of software entities comply with predetermined rule sets based on reasonable evidence or experience. The software credibility evaluation technology based on multi-dimensional trustworthy attributes is the core basis for the implementation of trustworthiness process control and trustworthiness management, and it is a key problem to be solved urgently in the development of trustworthy software. [0003] At present, in order to deal with the complex calculation logic in the process of software credibility evaluation, domestic and foreign researchers have proposed a number of software credibility ev...
