Abstract: In order to solve the trust problem between nodes in P2P network, it proposes the P2P network trust model Super Trust based on super-peer. In Super Trust, for the trust calculation of ordinary nodes within the same group, it uses the local trust information of the node and the recommendation trust information of owning group to determine the trust value of the target node. The trust evaluation of super node uses the global trust way of the super node within the group computational nodes. Also it puts forward noisy feedback information filtering algorithm to filter the false ｏｒ unjust evaluation which provided by malicious node. Experimental results show that: This model overcomes some of the limitations of existing models, which can effectively deal with malicious attacks, slander, fraud, conspiracy.
