EFFICIENT, FAULT-TOLERANT AND DISTRIBUTED KEY AGREEMENT FOR ARBITRARY DEPLOYMENT IN MANETSOctober 1st, 2004
Military command and control require that information be communicated to the appropriate groups and only with the utmost security. The environment envisioned by the Objective Force is mobile ad-hoc and consists of a large number of (heterogeneous) resource- constrained nodes deployed in a hostile field of limited bandwidth, unreliable channels, frequent node failures, where usually there is not infrastructure for communications, and it must be dynamically generated. The challenge lies in designing secure group communications that can be applied to such dynamic, constrained FCSs. In this work we develop a secure, fault- tolerant and scalable (for increasing number of users) contributory key agreement scheme (KA) for multicast communications. By generating hierarchy, applying improved and more resilient contributory protocols to smaller subsets of nodes, focusing on the exact topology of nodes deployed in the network, and by exploiting the redundancy issued by the topology itself, we suc
