An ID-Based Key Predistribution Scheme for Wireless Sensor Networks

Providing a suitable key establishment scheme 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 new key predistribution scheme for wireless sensor networks. By applying the ID-based technique, the proposed scheme can establish a unique pair-wise between two nodes and authenticate each other by fewer messages. In this scheme a sensor needs not to transmit its implicit certificate, so it not only provides the explicit key authenticate but also offers low power.
