Secure Routing for MANET in Adversarial Environment
Nilima N. Patil, Kuldeep K. Vartha, Ashwini W. Wankhade and Sagar A. Patil, ,
Collection of mobile nodes is known as ad-hoc network in which wireless communication is used to connect these mobile nodes. A major requirement on the MANET is to provide unidentifiability and unlinkability for mobile nodes. There are various secure routing protocols have been proposed, but the requirement is not satisfied. The existing protocols are unguarded to the attacks of fake routing packets or denial-of-service broadcasting, even the node identities are protected by pseudonyms. We propose a new secure routing protocol which provides anonymity named as authenticated anonymous secure routing (AASR), to satisfy the requirement of mobile networks and defend the attacks. The route request packets are authenticated by a group signature and public key infrastructure, to defend the potential attacks without exposing the node identities. The cocept of key-encrypted onion routing which provides a route secret verification message, to prevent intermediate nodes from inferring a real destination. Simulation results have demonstrated the effectiveness of the proposed AASR protocol with improved performance as compared to the existing protocols.
