Abstract: Efficient Key Distribution is essential among sensor nodes. Pairwise and Triple Key Distribution in wireless sensor networks is established using Combinatorial Design. Sensor networks which are used in many applications require secure communication between the nodes. The need for secure communication is to protect the information from unauthorized access and to provide authentication between nodes. In this paper, the combinatorial Design which is used, is followed by Randomized key predistribution are applied to sensor nodes. The algorithm used in this scheme is to improve and increase the connectivity and resilience factor between the nodes. This scheme aims at increasing computation efficiency, communication and security.

Keywords: pair wise, triple key distribution, randomized key pre distribution, resilience
