Key management schemes play an important role on the security issue in wireless sensor network and they are preconditions to secure communications among sensors. Using hypercube model, a new key management scheme is presented. The scheme utilizes the nice properties of hypercube to propose novel technologies of generating pairwise key and delivering cluster key. The scheme solves two problems mainly: First, combing the structure of hypercube and two one-way functions, and giving an establishment scheme of pairwise keys, which has lower key storage than previous related works. Second, designing an algorithm of finding neighbor nodes in the path of delivering cluster key, and when some sensor nodes in the path are disabled, cluster key also can be delivered efficiently in a cluster. Analysis shows our researches are practical to large wireless sensor networks.
