Key management scheme for wireless sensor networks

A key pre-distribution scheme for wireless sensor network(WSNs):Hashed random key pre-distribution using multiple key spaces(HARPMS) is presented.In HARPMS,aimed at the group-based deployment model,the key space is partitioned into some subspaces,and in key distribution and setup phases the Hash chain technology is used to improve the WSNs resilience against node capture.The analyses show that compared with the traditional random key pre-distribution scheme for group-based deployment model,the HARPMS has the same connectivity but better performance in resilience against node capture.
