Network Security Analysis Based on Reputation Evaluation

To solve the security issues of network resources in file sharing, a reputation evaluation system was build based on resource trust degree. A set of reputation evaluation formula and method was developed to build trust model using the reputation evaluation method based on resource credibility and recommended reliability, and the reputation evaluation system was applied to network security. Through the trust mechanism, users can get the historical experiences of target nodes, thus the network resource security and the integrity of download resources are ensured. Users can use the model to select safer network resource service objects, and an incentive mechanism can play a part in selecting network resources.
