Mobile Ad hoc NETworks (MANETs) have many well-known applications in military settings as well as in emergency and rescue operations. However, lack of infrastructure and centralized control make MANETs inherently insecure, and therefore specialized security services are needed for their deployment. Self-certification is an essential and fundamental security service in MANETs. It is needed to securely cope up with dynamic membership and topology, and to bootstrap other important security primitives and services (such as secure routing and group key management) without the assistance of any centralized trusted authority. An ideal protocol must involve minimal interaction among the MANET nodes, since connectivity can be unstable.
