Multi-tier Framework for Optimizing Pairwise Key Predistribution in Sensory Applications

Abstract

Security has been always a prominent concern in Wireless Sensor Network (WSN) irrespective of the evolution of various scientific approaches that mainly mechanizes key management approaches to secure the communication system among the resource constraints sensors. Out of various key management approaches, pairwise key is one effective approach to ensure cost effective key management scheme; however, review of existing approaches shows that they still are characterized by various issues connected to optimized performance. Adopting analytical research methodology, the proposed system implements an optimized multi-tier framework for resisting key-based threats and it targets to introduce a lightweight pair wise predistribution of keys by joint integration of enhanced public key encryption and digital signature. The study outcome shows that proposed system offer a better security performance in contrast to existing pair wise predistribution of keys.
