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.
