摘　　要：为了保障传感网访问控制信息及传感数据的安全性,针对传感网的特点提出一种适于访问控制机制的密钥管理方案。该方案基于对称钥体制,通过双密钥链结构来实现路由节点的互认证及共享密钥的协商;通过在密钥链中植入秘密信息,实现路由节点与传感节点的互认证及密钥协商。该密钥管理方案扩展性强,适于大规模的传感网环境,在传感节点被捕获时不会泄漏其他传感节点的密钥,具有较高的安全性。In order to protect the safety of messages of access control and sensor data in wireless sensor network, a key management scheme adapted to access control mechanism is proposed in light of the characteristics of wireless sensor network. The scheme is based on symmetric key cryptography, and uses double-chains of key to realise mutual authentication between neighbouring router nodes and negotiation of shared key. Besides, when constructing sensor’s key chain, a secret is planted as the parameter to implement mutual authentication and key negotiation between router and sensor nodes. This key management scheme has good scalability, and is suitable to large scale wireless sensor network condition. When one sensor node is captured, the lost of its key will not give away the keys of other sensor nodes, so it has a higher security.
