Abstract

In this paper we propose a new key predistribution scheme for wireless sensor networks in which the sensors are arranged in a square grid. We describe how Costas arrays can be used for key predistribution in these networks, then define distinct difference configurations, a more general structure that provides a flexible choice of parameters in such schemes.We give examples of distinct difference configurations with good properties for key distribution, and demonstrate that the resulting schemes provide more efficient key predistribution on square grid networks than other schemes appearing in the literature. Book synopsis: This book constitutes the refereed proceedings of the 5th International Conference on Information Theoretic Security, held in Amsterdam, The Netherlands, in May 2011. The 12 revised full papers presented together with 7 invited lectures were carefully reviewed and selected from 27 submissions. Understanding the minimal requirements for information-theoretic security is a central part of this line of research. Very attractive is the mathematical neatness of the field, and its rich connections to other areas of mathematics, like probability and information theory, algebra, combinatorics, coding theory, and quantum information processing, just to mention the most prominent ones.
