Abstract

In this paper we propose novel deterministic key predistribution schemes using codes. In particular we use Reed Solomon codes to present key predistribution scheme, which is better than existing schemes in terms of connectivity. We show that selective node compromise attack cannot be launched, because there is no clever way of knowing which nodes to compromise. An important advantage of our scheme is that we can increase the scalability of the network without redistributing keys in the existing nodes.
