ASROP : AD HOC Secure Routing Protocol

Abstract

Mobile ad hoc networks (MANETs) are a new concept of wireless communications for mobile devices, which offer communications over a shared wireless channel without any pre -existing infrastructure. Their wireless nature and self-organizing capabilities are some of MANET's biggest advantages, as well as their biggest security restrictions. Forming end -to-end secure paths in such MANETs is more challenging than in conventional wireless cellular/wired networks due to the lack of central authorities. An atta cker can easily disrupt the routing process by injecting false control messages, changing the paths of packets or simply by blocking the packets of other nodes. In this paper, we propose a novel efficient secure routing protocol, named ASRoP, to effectivel y secure the routing discovery process in ad hoc networks. ASRoP provides powerful security extensions to the reactive AODV protocol, based on Diffie -Hellman (DH) algorithms and our modified secure remote password protocol. The simulation results show the efficiency of the proposed ASRoP protocol, and its cost towards both the users and the network. ASRoP promises to offer a real opportunity to prevent attacks related to lack of authentication without degrading routing performance.
