Abstract: To achieve security in wireless sensor networks, it is important to be able to encrypt messages sent among sensor nodes.
Keys for encryption purposes must be agreed upon by communicating nodes. Due to resource constraints, achieving such key
agreement in wireless sensor networks is nontrivial. Many key agreement schemes used in general networks, such as Diffie-Hellman
and public-key-based schemes, are not suitable for wireless sensor networks. Predistribution of secret keys for all pairs of nodes is not
viable due to the large amount of memory used when the network size is large. Recently, a random key predistribution scheme and its
improvements have been proposed. A common assumption made by these random key predistribution schemes is that no deployment
knowledge is available. Noticing that, in many practical scenarios, certain deployment knowledge may be available a priori, we propose
a novel random key predistribution scheme that exploits deployment knowledge and avoids unnecessary key assignments. We show
that the performance (including connectivity, memory usage, and network resilience against node capture) of sensor networks can be
substantially improved with the use of our proposed scheme. The scheme and its detailed performance evaluation are presented in this
paper.
