无线传感器网络的许多应用都是为了实现能源效率和要求安全的数据通信。为了在无线传感器网络中实现安全，能够对传感器节点之间发送的消息进行加密是非常重要的。由于无线传感器网络资源的有限性，密钥管理任务具有挑战性。本文介绍了无线传感器网络的两种密钥管理方法，可以处理节点添加、节点妥协和定期更新密钥等事件。第一种是基于二叉树的方法，用于生成簇内通信的簇KeyCK和簇间通信的公共簇KeyCCK。第二种是dh密钥交换方法，采用最小通信和存储的方式进行密钥管理，保证了不被窃听和内部攻击的安全性。我们的密钥管理方法避免了在通信中使用公钥。
Many applications of wireless sensor networks are used to achieve energy efficiency and require secure data communications. To achieve security in wireless sensor networks, it is important to be able to encrypt the messages sent between sensor nodes. The key management task is challenging due to resource constrained nature of wireless sensor networks. We are introducing two key management methods for wireless sensor networks, which can handle events like node addition, node compromise and key refresh at regular intervals. The first one isBinary Tree Based Method, used to generate Cluster KeyCK, for intra cluster communication and Common Cluster KeyCCK, for inter cluster communication. The second one isDH Key Exchange Methodperforms key management with minimum communication and storage at each node which ensures the security from eavesdropping and internal attacks. Our Key management methods avoid the usage of public key in communications.
