摘　　要：在无线传感器网络中,网络节点的成簇算法是实现对传感器网络高效节能管理和应用的有效途径为了提高网络的安全性和寿命,提出了一种基于随机并行簇头选举算法和密钥预分配方案,在假设的网络模型中,均匀地选举簇头节点,并且实现对恶意节点的识别和删除,在数据通信阶段通过加密算法实现数据通信的安全性,从而有效地实现网络寿命的延长和数据通信的安全。In wireless sensor network, cluster algorithm of nodes is an effective approach and key technology to implement energy saving and flexible management. To improve security and lifetime of clustering network, a secure clustering was proposed based on the random and parallel cluster header election algorithm and pre-distributed key scheme. In hypothetical network model, it can elect the cluster header nodes and identify and get rid of malicious nodes, and in data telecommunications, the communication security can be achieved by using encryption algorithm and thus the network lifetime can be prolonged.
