Abstract :
We describe a novel Distributed Key Establishment (DKE) protocol in Disruption (Delay) Tolerant Location Based Social Wireless Sensor and Actor Networks (DTLBS-WSAN). In DKE, we propose that sensor nodes use neighboring signatures to establish their keys. Pre-distributed keys are used by actor nodes to strengthen communication security. We show that nodes can get guaranteed security when actors are connected and cover the network area and high security confidence can be achieved even without actor nodes when the adversary (malicious node) density is small. In DTLBS-WSANs, key (certificate) establishment, storage and look up are performed in a distributed way. Multiple copies of a certificate can be stored at nodes to improve key security and counter the adverse impact of network disruption.
