Pairwise key issue plays a key role in sensor networks security.An approach on pairwise key establishment based on location awareness is proposed.The algorithm encodes sensor nodes on a hybrid hypercube model with information of nodes’ expected location.Experimental results show that the algorithm has nice features such as higher probability of direct key establishment,reasonable storage cost and good scalability on network scales.
