Trust Degree Based Inter-Domain Routing Mechanism

Current inter-domain routing does not verify the reality of the received routes,it may cause the large-scale spread of false routes.To filter false routes,trust is introduced to inter-domain routing and an Trust Degree based Inter-domain Routing Mechanism(TDIRM)is proposed in this paper.The main idea of TDIRM is computing the trust degree of candidate paths and selecting the best path according to the trust degree.In TDIRM,Some ASes are selected to build a Chord ring for publishing and acquiring trust information of routing.ASes that can detect the false paths publish the trust information in the Chord ring,and other nodes can obtain the trust information from the Chord ring,compute the trust degree of the routes and select the trustworthy route information to distribute.The experimental results show that TDIRM can filter the false routes timely and improve the trustworthiness of routing.
