A Trust Evaluation Model Based on Multiple Services Attributes

According to the node self-service features,representative multi-service properties are abstracted and a trust evaluate model based on multi-service properties is proposed.The service requester will judge the multi-service properties of the services providers according its own preference,and decide whether the transaction will begin.After the transaction,the service requester calculates the differences in degree of quality of services based on the actual services quality received and the services quality which the service provider claimes.So as to judge the credibility of service providers,and the corresponding rewards and punishments and trust update.Simulation results show that the model can be more accurate assessment of the nodes trust can effectively curb various types of malicious node attacks.When a high malicious proportion of nodes happen,the system can still maintain a relatively high rate of successful transactions.
