Advanced Secure Intrusion Detection System for MANET

Abstract: In this project, we define solid privacy requirements regarding privacy-maintain routing in MANET. Then we propose an secure routing scheme to offer complete unlink ability and content un- observability for all types of packets. It is efficient as it uses a novel combination of group signature and ID-based encryption for route discovery. Security analysis demonstrates that it can well protect user privacy against both inside and outside attackers. Privacy- preserving routing is crucial for some adhoc networks that require stronger privacy protection. A number of schemes have been proposed to protect privacy in adhoc networks. However, none of these schemes offer complete unlinkability or unobservability property since data packets and control packets are still linkable and distinguishable in these schemes. In this paper, we define stronger privacy requirements regarding privacy-preserving routing in mobile ad hoc networks. Then we propose an secure routing scheme to offer complete unlinkability and content unobservability for all types of packets. It is efficient as it uses a novel combination of group signature and ID-based encryption for route discovery. Security analysis demonstrates that it can well protect user privacy against both inside and outside attackers. We implement it on ns2, and evaluate its performance by comparing with AODV. The simulation results show that it not only has satisfactory performance compared to AODV, but also achieves stronger privacy protection than existing schemes.
