Abstract :
Wireless sensor networks (WSNs) are usually deployed in the work area for a long time, but most key managements are not stable enough that brings great threats to the WSNs. In this paper a multi-phase key pre-distribution scheme based on hash chain (HM scheme) is proposed in which the work time is divided into phases with different key matrixes to guarantee the safety of WSNs. Simulation results prove that HM scheme performs with perfect stability even though the nodes change greatly.
