摘　　要：在基于簇的三维水声传感器网络中,将布置区域划分为多个正方体的簇空间。在簇头节点间,提出通过相对坐标位置产生节点间的验证对称密钥;在簇内节点间,提出通过改进的对称多项式方法产生节点间的验证对称密钥。网络中的节点进行通信交流时都是采用基于对称矩阵的通信对称密钥,实现节点间的通信全连通。相比于传统的传感器网络密钥管理方案,本方案能够实现节点撤销和密钥更新,具有较高的可扩展性、可靠性和较低的开销。由于事先采用了轻量级节点认证机制,本方案能够很好地抵御节点间信息交流时的DoS攻击,特别是汇聚攻击。由于采用了三维密钥,本方案比单一的单向哈希链方法能更加有效地抵御簇头节点妥协。In the three-dimensional acoustic sensor network based on cluster,the decorated area is divided into multiple rooms which are cubes.Among cluster head nodes,the symmetric key is generated to verify nodes by relative coordinates.Between nodes within the cluster,the symmetric key is generated to verify nodes by modified symmetric polynomials.When the nodes communicate in the network,they generate symmetric key which is used to communicate by symmetric matrices.It realizes complete connection in communication.Compared with the previous key management scheme for sensor network,this scheme can realize node revocation and key update,and it has high scalability,reliability and low cost.This scheme can also effectively resist DoS attack especially gather attack between nodes＇ communication because of first lightweight node authentication mechanism.Compared with one-way hash method,this scheme can more efficiently resist cluster head compromise because of three-dimensional key.
