Reputation Based Intrusion Detection System with Threshold Cryptography for Wireless Mobile Ad Hoc Networks

Abstract

In recent years ad hoc networks are becoming an important research due to the selforganization network, dynamically changing topology, temporary network life and equal relationship among member of nodes. However, some of the properties of ad hoc network make the security problem more serious. DoS (Denial of service) attack is the most popular attack of the security problem, which can decrease the network performance or consume the resource of the network. The most famous DoS attacks are Black Hole attack and Flooding attack. Several methods proposed to defend these attacks can be classified into two types: authentication based technique and observation based technique. In this paper, we propose a reputation based intrusion detection system (RIDS) which combines the advantages of the above two techniques to achieve high performance and less computation and control packet overheads.
