Abstract

Key Predistribution Schemes (KPS) are efficient key management solutions that are well suited to establish lightweight symmetric keys even in resource starved environments, like low cost Internet of Things (IoT). This paper uses Chinese Remainder Theorem (CRT) to propose an energy efficient and deterministic KPS for distributed ad hoc networks, that we name as CRT-KPS. We theoretically establish the effectiveness of CRT-KPS in term of crucial metrics. Comparative study establishes that our proposals have better balance in overall performance as compared to state-of-the-art schemes and should find wide applications in IoT systems (specially for resource starved end devices).
