Digital Sensors and Sensor Sysstems


Abstract: Wireless sensor networks (WSN) has been widely applied to many fields such as disaster management and military operations. Clustering allows WSN more scalable and makes sensors Energy-saving. As the sensor nodes in WSN are all resource-limited devices and usually deployed unattended in the hazardous environments, security becomes more crucial. Authentication and key negotiation are the fundamental protocols to build a secure WSN. Public key algorithm and digital signature widely used in traditional networks are not very suitable for WSN. In this paper, we propose an authentication scheme for clustered WSN. The proposed scheme is based on LU decomposition which is less computation, storage, communication cost than the schemes based on public key technology. We also present security and performance analysis.


Keywords: WSN, Cluster, Authentication, LU Decomposition.
