| 摘 要： | 文中借鉴人类社会对交易过程中信任的评估和习惯,提出了一种在P2P网络中基于交易代价的信任评估模型,着重考虑了节点之间交易代价对信任值变化的影响,并给出了信任值计算的方法和仿真实验.实验结果表明该信任评估模型在对节点恶意行为的识别上,其成功率上要优于不考虑节点之间交易代价的模型.

| Abstract: | Learning from the trust evaluation and habits in the transaction process of the human society,this Paper presents a trust evaluation model based on transaction costs of P2P network.The impact of the nodes transaction costs which cause the trust value change is considered focus.And this Paper gives the methods of trust value calculation are presented.Experimental results show that the success probability of the recognition of the malicious behavior using the proposed trust evaluation model is better than which of the model without considering transaction costs between nodes. |
