Key Predistribution Using Transversal Design on a Grid of Wireless Sensor Network
Sushmita Ruj, Subhamoy Maitra and Bimal Roy
We propose a deterministic key predistribution scheme in a Wireless Sensor Network (WSN), in which each sensor node (identifiable with a block in transversal design) is placed at each grid intersection point. Any two sensor nodes, when they are in the Radio Frequency (RF) range of each other, are allowed to communicate (in an encrypted manner) if they share a common secret key. We analyze the connectivity of the network taking the RF radius into account. Further, we study the security of the network when some sensor nodes are compromised to the adversaries.
