Abstract

We present a deterministic key pre-distribution scheme using projective planes where the nodes are organised hierarchically through a structure of (p 2 + p) -nary tree, where p is prime. Our scheme is incumbent to more efficient resilience and connectivity compared to the existing schemes. Each node in our scheme requires to store significantly less number of keys. Furthermore, any number of nodes can be intrinsically inserted in the system by attributing a very few keys to the recently introduced nodes only. Another interesting feature of our scheme is that such node insertions are done without interfering the normal functioning of the existing organised network.
