Abstract:

Mobile Ad-Hoc Networks (MANETs) are becoming increasingly applicable in different fields. Securing MANETs routing protocols is considered as one of the most difficult areas to deal with as opponents can add themselves to a MANET using the existing common routing protocols. This paper proposes a new routing protocol; ARANz, which is an extension of the original Authenticated Routing for Ad-Hoc Networks (ARAN). Apart from the authentication methods adopted from ARAN, ARANz aims to increase security, achieve robustness and solve the single point of attack and failure problems by introducing multiple local certificate authority servers. Via dealing with the network as zones and using restricted directional flooding, our new model exhibits better scalability and performance. Through simulation we evaluated ARANz and compared it with the original ARAN. Simulation results show that ARANz is able to effectively and efficiently discover secure routes within relatively large networks with large number of mobile nodes.
