Research on trust transitivity and aggregation in evidential trust model
Current trust models had some certain disadvantages in dealing with trust transitivity and trust aggregation.Firstly,these models ignored the feedback trust measurement on the direct recommender in the process of trust transitivity.Secondly,the models contained the problems of information loss or re...

| description | Current trust models had some certain disadvantages in dealing with trust transitivity and trust aggregation.Firstly,these models ignored the feedback trust measurement on the direct recommender in the process of trust transitivity.Secondly,the models contained the problems of information loss or repetitive calculation for the limits in analysis and dis-posal of the dependent relationships among referral chains.A new evidential trust model was proposed,and the problems existed in current methods for transferring and aggregating trust relationships were addressed by combing D-S evidence with graph theory.It can be seen from the simulation results that compared with existing trust models,the proposed model is more robust on defending malicious attacks for various strategy cheating and collusion,and has more remarkable en-hancements in the accuracy of trust measurement. |
