摘　　要：随着无线传感器网络的发展与广泛应用,无线传感器网络的安全性也得到越来越多的关注。无线传感器节点通常部署在露天环境,或敌对环境中,所以对于传感器网络的安全保障,就显得尤为重要。而安全的密钥管理机制,是传感器网络中数据加密和安全通信的前提。受限于传感器节点存储空间与性能,传统网络中应用的安全密钥机制,并不能通用于无线传感器网络中,这也对无线传感器网络节点安全带来很大的挑战。许多学者针对传感器节点的特性,提出许多密钥管理机制,以提高无线传感网的抗风险性能。With the development and wide application of wireless sensor networks, more and more attention has been paid to the security of wireless sensor networks （WSN）. Wireless sensor nodes are usually deployed in the open environment, or in the hostile environment, so it is particularly important for the security of sensor networks. The secure key management mechanism is the precondition of data encryption and secure communication in the sensor network. Constrained by the storage space and performance of sensor nodes, the secure key mechanism applied in traditional networks cannot be used in wireless sensor networks, which also brings great challenges to the security of WSN nodes. Many schol- ars have proposed a number of key management mechanisms to improve the anti-risk performance of wireless sensor networks.
