摘　　要：提出基于超级节点的P2P网络信任模型—Super Trust。在Super Trust模型中,对节点的信任值采用了组内直接信任,组内间接信任和组间信任相结合的方式,从而提高了信任值计算的精确性;此外,通过引入超级节点机制,提高了系统交互的成功率。实验结果表明,与基于推荐信任传统模型和RBTrust模型相比,Super Trust具有较高的交易成功率,并且在不同的恶意节点攻击模式下具有较高的成功交易率。P2P trust model based on super node is proposed,in the Super Trust model,the node trust value using the direct trust and indirect trust within the same cluster and trust between clusters improve the accuracy of the trust value computation; In addition,the success rate of the system interaction is improved by introducing mechanism of super node. The experimental results show that Super Trust has higher transaction success rate compared with the model based on the traditional recommendation trust model and RBTrust,and Super Trust has the high success transaction rate under the different malicious node attack.
