A Trust Model Combining Reputation and Credential

Most current reputation models fail to calculate peerspsila reputation accurately when there is little transaction history between the peers. To this end, this paper presents a trust model combing reputation and credential which accepts inputs of both feedback and credential. The model is based on reputation-based trust model, and according to the correlation of credential and reputation, the model can derive credential trust from the credential adaptively, then combine the credential trust and reputation to get the overall trust value. Analyses and simulations show that this model can improve the accuracy of the trust value computation significantly.
