New Algorithms for the Efficient Design of Topology-Oriented Key Agreement Protocols in Multi-Hop Ad Hoc Networks

Securing group communications in resource constrained, infrastructure-less environments such as Mobile Ad hoc NETworks (MANETs) has become one of the most challenging research directions in the areas of wireless network security. MANETs are emerging as the desired environment for an increasing number of commercial and military applications, addressing also an increasing number of users. Security on the other hand, is becoming an indispensable requirement of the people modern life for all these applications. The inherent limitations of such dynamic and resource-constraint networks impose major difficulties in establishing a suitable secure group communications framework.
