Problems solved by technology

However, the sharing and reuse of components is based on the trust of component users that the components can achieve the expected functions. Because the components themselves have various levels (common basic components, domain common components, application-specific components, etc.), involving a wide variety of businesses, the components themselves There is no mature method and technology in the industry to measure the credibility of
But this does not mean that in a specific field we cannot find a method for measuring the credibility of components

Embodiment Construction

[0027] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] refer to figure 1 , which shows the credibility measurement steps of an entropy-based component credibility measurement method of the present invention, the method specifically includes:

[0029] Step S101, establishing a credibility measurement framework;

[0030] Preferably, the method further includes: measuring credibility through process evidence.

[0031] More preferably, the credibility of each stage is measured by measuring the degree of deviation from the intention of the previous step of the product.

[0032] refer to figure 2 , shows a credibility measurement frame diagram of an entropy-based component credibility measurement method of the present invention.

[0033] In practical applications, credible evide...

Abstract

The present invention provides an entropy-based component credibility measurement method, which includes: decomposing the main function points of the component; recording the credible evidence of each function point in the requirements stage, design stage, coding stage, and test stage; Calculate the trusted evaluation value Pi of each stage in the function point according to the recorded credible evidence; calculate the entropy of each function point; calculate the entropy of the component, and judge the credibility of the component. The measurement of the credibility in the invention focuses on the process evidence, quantifies the credibility index through the process evidence, and uses the information entropy as the credibility measurement standard to measure the credibility of the component more effectively.

Description

technical field [0001] The invention relates to the field of credibility measurement, in particular to an entropy-based component credibility measurement method. Background technique [0002] The concept of software trustworthiness, or the concept of "credibility", comes from trusted computing. With the expansion of "credibility" requirements from hardware to software, the industry's understanding of "trustworthiness" is also expanding. TCG believes that "if the behavior and results of the system are always expected and controllable, then the system is credible." Dependable computing, which emphasizes reliability and availability, proposed and advocated by fault-tolerant experts, means that the services provided by computers can be Demonstrate that it is trustworthy, and this trustworthiness is demonstrable; domestic Wuhan University Zhang Huanguo and others proposed that trustworthiness is reliable, usable and safe. [0003] Component technology is an important means of so...
