Abstract

Sensor networks are suitable for a variety of commercial and military applications due to their self-organization characteristics and distributed nature. As a fundamental requirement for security functionality in sensor networks, key management plays a central role in authentication and encryption. In this paper, we describe an Adaptive Key Selection (AKS) scheme for multi-deployment in sensor networks and analyze the scheme in the aspects of security, connectivity and overhead. Our analysis shows that the AKS scheme can greatly improve the connectivity of sensor nodes while maintaining the security of an existing multi-deployment scheme.
