| 摘 要： | 为了解决分布式结构给P2P网络带来的安全问题,提出了一种适用于P2P网络的恶意节点检测机制,在此基础上设计了P2P网络恶意节点检测模型。在网络中定义针对不同攻击的节点行为规范(NBS),并根据NBS对节点之间发送的消息进行比较,找出与多数节点发送消息具有不同内容的节点,定义为恶意节点,然后利用分布式证书机制将恶意节点清除出网络。实验结果表明,该机制具有较好的可靠性和有效性。

| Abstract: | To solve the new security problem of P2P networks caused by its distributed architecture,a malicious node detecting mechanism based on node behavior specifications(NBS) is proposed.First,different NBS are defined in the P2P network against different kinds of attacks.We can compare the messages sent by different nodes in P2P networks based on the NBS.A node is defined as a malicious node if the messages it sent are different with others.When the malicious node is found,a distributed authentication scheme is ... |
