Research On Trust Model In The P2P Resource Sharing Of The Education Network

At present the government of our country has been making gradually stepped up efforts to make the construction of the education network and has lead this work to a booming stage, with Tsinghua University and other ten national colleges campus network as a representative of the education network, they has been dedicated to the development of the education network of P2P technology. Especially in Maze and six-dimensional space is known to everyone. P2P network’s openness makes the quality of sharing resource and the speed of download improved, but this can be followed by a series of security issues and problem of resource replica and flooded. Therefore, it is important to solve the credibility problem of P2P resource sharing in education network relying on trust model of trust management technology.This paper studies several kinds of trust model of the trust management technology, as well as their working process and characteristics, Considering the particularity of education network is that it has a large number of applications of resources sharing and downloading, and I found that the trust model has played a big role in terms of safety protection. But in view of the network education network’s special, how to make a reasonable use of nodes in the network is very critical, this paper proposes a trust model that can improve the utilization efficiency of node-responsibility traceable trust model of the education network. The trust model puts forward original certification resources and continuous protection certification resources, gives a Deeps and a Protected as quantitative standards. The Deeps is for nodes just join in the network to have their due credit value as soon as possible, and the Protected is for nodes who wants to turned good. This it to say the RITM trust model is proposed on the basis of improving the utilization ratio of nodes in P2P education network, or to say the mode is to make full use of the resources of each node at the same time safeguard the safety of the networks far as possible reasonable.This article uses the PeerSim simulation platform building experimental environment, and take the new mode to compare with the previous two representative mode—the EigenTrust and the PeerTrust. In combination with the Gnuplot simulation for mapping of the experimental data to a visual rendering, it shows that the proposed model is able to make the new join come in handy as soon as possible, it can also make the nodes really wants to turn good increase its trust value to afford service. This trust models plays a great significance for future application in the education network.
