Secure and Anonymous On-demand routing for Adhoc Networks

Vinothkumar J, Dr. U. Karthikeyan

Abstract


Mobile adhoc networks require stronger privacy protection due to the open nature of their media. Schemes such as Privacy preserving location aided routing, Anonymous on-demand routing and Anonymous location aided routing uses either one time or long term public key cryptosystems or combination of both achieving only partial anonymity and unobservability. Also, these schemes depend on public key cryptography and hence incurring high computation overhead. Our proposed technique overcomes these disadvantages by employing group signature and private key based encryption together instead of public key cryptosystem. This scheme is thought to offer complete unobservability of both types. Our proposed technique provides protection against wormhole attacks in addition to node compromises and Sybil attacks. Additionally, we try to improve packet delivery ratio and latency
