Abstract: Dynamic IP configuration is a major requirement for mobile ad hoc networks that grows from one node to many. Recently, a number of schemes for such IP assignments have been proposed in the literature. But very few of them consider security aspects while assigning the addresses among the nodes. In this paper, we propose an authenticated dynamic IP configuration scheme that can securely allocate IP addresses to the individual nodes of a MANET. In this scheme, each node of a MANET can generate new unique IP address from its own IP address for a new authenticated host. The authentication for address configuration is done with the help of a trusted third party and as such it is capable of handling the security threats associated with a general dynamic IP configuration. Performance analysis and simulation results show that, even while deploying the security attributes, the communication overhead and addressing latency of our proposed addressing scheme are at par with and in some cases much better than some popular similar existing schemes.
