AOR-ID-KAP: An authenticated one-round identity-based key agreement protocol for wireless sensor network

Abstract

Today, Wireless sensor network has large applications in different areas such as home appliances, healthcare, defenses, submarine, weather forecasting, etc. Sensor node gathers data, processes it and transmits data to the other node in the sensor network. To enable two nodes that communicated, they need a secret key which protects them over the public wireless network. Since the resource-constrained sensor node in WSN has insufficient memory that incapable to store secret keys. So, there is a need for the distribution of key over the network. The keys distribution on resource-constraints sensor nodes in the WSN is the challenging area of interest. Though, the resource constraints behavior of sensor node restricts to manage a lot of keys in WSN. Many solutions have been proposed for WSN recently. In this article, we demonstrate how public key cryptography, especially, identity-based encryption gives the right approach for key distribution on WSN without interacting the nodes in the network. Besides, we inspect several highly optimized, energy and memory efficient, and scalable variant of Elliptic curve cryptography that is quickly and flexible to integrate on WSN. Further, we examine another light-weight pairing based cryptography implementation and show the feasibility of pairing-based cryptography in WSN. We then proposed a one-round identity-based key agreement protocol (AOR-ID-KAP) based on the light-weight pairing-based cryptosystem. We show that our proposed scheme AOR-ID-KAP is authenticated and scalable to large network size, and secure against man-in-middle-attack, and node capture. In terms of computational cost, bandwidth cost and message exchange, our proposed system performed better as compare to the other related schemes.
