| 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. |

| Keywords: | intrusion detection peer-to-peer reputation CRC |
