On-Demand Key Distribution for Mobile Ad-Hoc Networks

<p>Mobile ad-hoc networks offer dynamic portable communication with little or no infrastructure. While this has many benefits there are additional shortcomings specific to wireless communication that must be addressed. This research proposes gossip-based on-demand key distribution as a means to provide data encryption for mobile ad-hoc networks. This technique uses message keys to avoid encrypting and decrypting a message at every node. Other optimizations used include secure channel caching and joint rekey messages. The use of gossip makes the scheme robust to node failure. Experimental results show only a 15% increase in end-to-end delay with a node failure rate of 10%. The percentage of messages successfully delivered to nodes stays between 91-98% under the same 10% node failure rate. The network load is distributed to all nodes in the group preventing overload and single points of failure.</p><p>This work has been selected by scholars as being culturally important and is part of the knowledge base of civilization as we know it.
