Deterministic Key Distribution in Wireless Sensor Network Using Finite Affine Plane
Security of large scale densely deployed and infrastructure-less wireless networks of resource limited sensor nodes requires efficient key distribution and management mechanisms. Key management is an important area of research in Wireless Sensor Networks (WSN), because resource constraints make security protocols difficult to be implemented. Key pre-distribution, a new combinatorial scheme for key distribution that makes use of finite plane. This gives rise to a new type of combinatorial design. Which involves preloading keys in sensor nodes, has been considered as the best solution when sensor nodes are battery powered and have to work unattended.
