When wireless sensor networks were working,some nodes failed because of environment or energy factors.In order to recuperate the networks,evicted the sensor nodes out of the networks and added some new nodes to the networks.Based on the reliable pairwise key-updating scheme,this paper proposed the scheme to protect the networks security.The scheme can extend and shrink the keys by Blom matrix with the network topology changes to prevent the adversary from utilizing the captured keys.Comparison the reliable pairwise key-updating scheme,the scheme can outperforms in terms of memory and computation overhead.
