Abstract: |
Wireless sensor networks (WSN) are networks consisting of thousands of lightweight nodes, each equipped with an
environmental sensor and a small range radio. Sensed information is collected through multi-hop paths by a few
powerful nodes called base stations (BS). Resource-constrained nodes render new challenges for suitable routing,
key distribution, and communication protocols. Probabilistic key pre-distribution schemes (PKPSs) were
developed to deal with limited memory of a single node and high number of potential neighbours. This paper presents a
new idea of group support for authenticated key exchange that substantially increases the resilience of an underlaying
PKPS against the threat of node capturing.
