Immunizing the SAODV protocol against routing information disclosure

Secure routing protocols presents one of the most important challenges of Mobile Ad hoc Networks (MANETs). This is due to their special characteristics such as shared wireless medium, stringent resource constraints and highly dynamic network topology. This paper presents a solution to the problem of routing information disclosure and traffic analysis in a new way that doesn't require exchanging a group secret key between one-hop neighbors. In addition, the proposed solution maintains the routing data integrity and node authentication features. Furthermore, the solution provides a new method for securing neighborhood discovery (ND) using PKI. © 2011 ICITST.
