中文摘要：
P2P环境下文件共享中节点的信任建立是彼此进行安全交互的前提,现有的信任关系的建立依赖于可信的第三方,但在P2P网络中没有中心服务器和可信第三方提供担保,这种节点信任关系的建立相当困难。为此,借助演化博弈理论提出了一种信任建立博弈模型,从而为P2P文件共享中陌生节点提供信任保障。运用复制动态原理对信任建立博弈模型进行了求解分析,并对P2P文件共享系统的稳态进行了分析,给出初步仿真实验结果。
英文摘要：
In the P2P file-sharing environment the securing co-operation is based on the trust between the strangers node. Current establishment of trust relationship depends on the credible third party. But there is no central server and the trusted third-party guarantees in P2P networks,so it’s very difficult to establish the trust relationship of the nodes. This paper proposed a game model of trust establishment based on the evolutionary game theory,in order to provide trust assurance for the strange nodes in the P2P file-sharing environment. Used the dynamic replication to analyze the trust establishment game model and also the steady-state of the P2P file-sharing systems. In the last,gave a preliminary simulation results.
