Research on dynamic and hybrid key management scheme for wireless sensor networks
摘要
Abstract
In order to protect the sensing data not to be illegally eavesdropped,tampered and destroyed,a dynamic and hy-brid key management scheme based on clustering structure for wireless sensor networks is proposed in this paper. Each cluster head randomly generates sub-key matrix. The cluster head assigns different one-way communication key to each node by using dynamic base key. The overlapping section of sub-key matrix of adjacent cluster is regarded as the base key which generates the pair-key. When the remaining energy of the head is lower than threshold or is captured,it is needed to generate a new cluster head,and the new sub-key matrix will be generated to achieve dynamic key updating. Compared with the existing protocols,DH-KM scheme supports network topology changing,and is easy to process the new node addition. The scheme has better security and good scalability,and can save storage spaceof the nodes.关键词
