In peer-to-peer content distribution the lack of a central authority makes authentication difficult.Without authentication, adversary nodes can spoof identity and falsify messages in the overlay. Thisenables malicious nodes to launch man-in-the-middle or denial of-service attacks. In this paper, we present a trust based content distribution for peer-to-peer overlay networks, which is built on the trust management scheme. The main concept is, before sending or accepting the traffic, the trust of the peer must be validated. Based on the success of data delivery and searching time, we calculate the trust index of a node.Then the aggregated trust index of the peers whose value is below the threshold value is considered as distrusted and the corresponding traffic is blocked. By simulation results we show that our proposed scheme achieves increased success ratio with reduced delay and drop |
