%X Key management is the foundation of security mechanisms in WSN (Wireless Sensor Network). This paper, based on hash chain based key distribution scheme, made some improvements on form of key pool, keys pre-distribution scheme and establishment of pair-wise key. The improved scheme can take full advantage of hash chains, provide more secure network connectivity and enhanced network survivability. Theoretical analysis and simulation results verify the effectiveness of the improved scheme.
