Abstract
A wireless sensor network (WSN) consists of tiny autonomous sensor nodes with some constraints. There are organizations having moderately necessitates of these kind of networks. So, security become an indispensable concern in WSN, due to potential adversaries. To overcome the security problem, keys are pre-loaded to the nodes before deployment. Among all key distribution schemes, deterministic key pre-distribution scheme (KPS) using combinatorial design is efficient regarding security aspect. In this paper, a deterministic approach, based on combinatorial design, for key assignment before the network deployment has been presented. Here the quasi-symmetric design which is of triangle-free is being used to present the new KPS for sensor networks. Due to this approach each sensor node either will contain a key-chain or will communicate through a key-path. This will improve the resiliency and achieve the sufficient level of security in the network. This design can also be used when a large number of nodes are being deployed in WSN.
