To enhance security in Ad-Hoc networks,it is important to evaluate the trustworthiness of other nodes without centralized authorities.In this work,authors focus on the evaluation of trust evidence in Ad Hoc networks.First,the authors introduce the metrics of the trust,the evaluation process is modeled as a path problem on a directed graph,where nodes represent entities,and edges represent trust relations.Using the theory of semirings,a trust evaluation model based on semiring（TD-SEMIRING） is developed,then two nodes can establish an indirect trust relation without previous direct interaction and introduce the application of this model in route election.At last,the feasibility of this model is analyzed.
