| 摘要: |
| 针对点对点网络节点信任关系以及交易可能性较小的特点,阐述基于核心节点的点对点信任网络模型.该网络模型中的网络节点以公有度和私有信任度进行聚类,依靠节点可靠度针对核心节点和普通节点分情况讨论，并给予相关解决方案.仿真实验结果表明：该信任模型不但具有抗恶意节点攻击的鲁棒性,同时在网络资源搜索时具有较低的评估计算量和通信开销. |

| Abstract: |
| In this paper,on account of the features of node trust relationships and smaller transaction possibilities in peer-to-peer network,a peer-to-peer trust network model is set forth based on its core nodes.Nodes in the network model are clustered according to their public reputation and private credibility.This paper discusses core nodes and ordinary nodes respectively relying on their node reliabilities and gives relevant solutions.The simulation results show that the trust model not only has robustness of anti-malicious node attacks but also has lower amount of assessment computation and communication overhead for network resources search. |
| Key words: peer-to-peer network trust and reputation core nodes private trust reliability |
