The vision of nomadic computing with its ubiquitous access has stimulated much interest in the Mobile Ad Hoc NETworking (MANET) technology. Those infrastructureless, self-organized networks that either operate autonomously or as an extension to the wired networking infrastructure, are expected to support new MANET-based applications. However, the proliferation of this networking paradigm is strongly dependent on the availability of security provisions, among other factors. The absence of infrastructure, the nature of the envisioned applications, and the resource-constrained environment pose some new challenges in securing the protocols in the ad hoc networking environments. In particular, the security requirements can differ significantly from those for infrastructure-based networks, while the provision of security enhancements may take completely different directions as well.
