Paper Title
On-Demand Secure Routing Protocol for Authentication and Data Integrity in MANET
Abstract
A mobile ad hoc network consists of mobile nodes that communicate in an open wireless medium. Adversaries
can launch analysis against the routing information embedded in the routing message and data packets to detect the traffic
pattern of the communications; thereby they can obtain the sensitive information of the system, like the identity of a critical
node. Privacy-preserving routing is crucial for some ad hoc networks that require stronger privacy protection. A number of
schemes have been proposed to protect privacy in ad hoc 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 unobservable secure routing scheme On-Demand Secure Routing Protocol to offer complete
unlinkability and content unobservability for all types of packets. On- Demand secure Routing protocol is efficient as it uses
a novel combination of group signature and ID-based encryption for route discovery. Security analysis demonstrates that
OSRP can well protect user privacy against both inside and outside attackers. OnDemand Secure Routing Protocol is
implemented on ns2, and evaluate its performance by comparing with Ad-hoc On Demand Distance Vector and MASK. The
simulation results show that On-Demand Secure Routing Protocol not only has satisfactory performance compared to Adhoc
On Demand Distance Vector, but also achieves stronger privacy protection than existing schemes like MASK.
