In accordance with the existing problem that the random key pre-distribution scheme of wireless sensor network can not acquire the high network connectivity probability and reach strong resilience against the nodes compromise simultaneously,a novel key pre-distribution scheme based on double chaotic map is proposed.In the scheme,the chaotic map is introduced to generate the chaos sequence with good randomness and self-correlation property.Nodes only need to preload a few ID keys in the pool and can establish pair-wise keys amongst all the sensor nodes with high probability.In addition,this scheme improves the method to generate the session key,reduces the probability of the key being cracked.The theoretical analysis and simulation experiments show that the whole network can afford the best security to the node capture attack and perform good ability in network connectivity.
