摘要：

入侵检测是P2P系统安全的关键技术之一. 该文提出一种基于信任度的入侵检测策略，使用改进的CRC校验算法对信任度进行评估，在此基础上使用多特征参数综合识别的入侵检测机制，可有效适应不同结构的P2P系统对入侵检测的要求. 实验和性能分析显示该策略具有较小的计算代价和良好的入侵节点辨识性能，表明了该策略的有效性.

关键词: 入侵检测, 点到点, 信任度, 循环冗余校验

Abstract:

Intrusion detection is a critical technique in information security for peer-to-peer networks. This paper proposes a new strategy of intrusion detection that can meet the requirements of peer-to-peer networks with various topologies by discriminating multi-parameters after calculating reputation using an improved CRC algorithm. Effectiveness of the strategy is verified in intrusion tests and performance evaluations as it has shown low computational complexity and strong capability of intruder discrimination.

Key words: intrusion detection, peer-to-peer, reputation, CRC
