Key establishment and management in wireless sensor networks are one of the important targets of security technology researches because traditional key cryptosystems are unsuitable for resource constrained sensor nodes.A novel scheme named Low-power Key Pre-distribution Scheme(LKP) was proposed.This scheme generated a combination of inherited key chain,stored the head key of the key chain and the first key of overlay of keys into each node,searched for better network connectivity between nodes according to the overlap of keys,and then analyzed the security of the LKP scheme.At last the performances of the LKP scheme such as energy consumption and capture probability were simulated.The results show that LKP scheme is better than q-composite random key pre-distribution scheme and multi-path key reinforcement scheme on security and energy.
