An Efficient LU Decomposition-based Key Pre-distribution Scheme for Ensuring Security in Wireless Sensor Networks

In this paper we propose an improved and efficient key pre-distribution scheme for wireless sensor networks. Our scheme significantly increases the storage efficiency and security than that of the previously proposed scheme based on LU decomposition. It also ensures node-to-node mutual authentication in a way that an eavesdropper cannot harm the network by monitoring the traffic flows in the network. We also present detailed performance analysis and compare our scheme with the existing schemes.
