An ID-Based Key Agreement Protocol for Wireless Sensor Networks

Providing a suitable key establishment protocol in wireless sensor networks is challenging due to all the characteristics of these networks, such as limitations of power, computation capability and storage resources. This paper presents a novel key agreement protocol for wireless sensor networks. By applying the ID-based technique, a sensor node and a security manager can achieve key exchange and fast mutual authentication. In this protocol a sensor node needs not to transmit its implicit certificate, so it not only provides the explicit key authenticate but also offers low power.
