A Trusted Virtual Network Construction Method Based on Data Sources Dependence

At present, the isolated and single data source cannot meet the needs of system security. Based on the research of the trusted computing theory, this paper creatively put forward a method to construct a trusted virtual network based on data source dependency. Firstly, the credibility of data source is calculated by the NEWACCU algorithm, and then, the trusted virtual network which is composed of the entity of data source is built dynamically by calculating the credibility between data sources, which will provide technical support for future credibility assessment and further research on information security. Taking the data of e-commerce platform as an example, the experimental results verify the effectiveness of the method.
