MANET secure key exchange using spraying diffie-hellman algorithm

With the proliferation of smart devices such as PDAs, smartphones and tablets having WIFI capabilities, applications orchestrating massive mobile ad-hoc networks (MANETs) are under active development. These networks would have the ability of running communications without the use of pre-existing infrastructure, allowing for a reduction of cost to carriers, setting up communication networks where no infrastructure is available, etc. For such utilities to be widespread, they must take into account the security of data transferred within. In this paper we propose an algorithm that will provide for a secure key exchange during conversation hand-shake, on which a secure channel can built upon. The algorithm assumes no prior knowledge and no user intervention, by using the inherent fluctuation of network topology in MANETs to allow for the discovery of an eavesdropper (if one exists).
