• Mutual authentication
• Wireless sensor networks (WSN)
• Elliptic curve Diffie-Hellman (ECDH)
• Timestamp

With increasing popularity of wireless sensor networks (WSN), the security issues related to such networks have become crucial. Most of the networks use shared key among all the nodes to make communicational overhead minimal. But it is vulnerable to many attacks like replay attack, node-compromise attack, impersonation attack etc. Further many traditional security mechanisms cannot be suitably implemented in WSN as resources are constrained in terms of power, energy and speed. In this paper, we propose a mutual authentication protocol based on timestamp in WSN which generates a new session key for each session. The proposed authentication approach requires light computational and communicational load and resist the major vulnerable attacks in WSN.
