A key management technique based on elliptic curves for static wireless sensor networks

摘要

This paper presents a key distribution scheme based on elliptic curve Diffie-Hellman (ECDH) key exchange for static wireless sensor networks with node addition. The proposed scheme relies on the transitory master key approach for secret key establishment and addresses the man-in-the-middle attack in ECDH key exchange. The major advantage of the proposed method compared with the state-of-the-art schemes is the high resilience offered by this scheme even if nodes are compromised in the initialisation phase. The communication overhead, computational cost and storage requirement of the proposed method is very less compared with the elliptic curve-based approaches available in the literature. The proposed scheme can also support large networks without affecting the security and efficiency. Copyright (C) 2015 John Wiley & Sons, Ltd.
