摘　　要：设计安全、可靠的密钥管理方案和协议是无线传感器网络安全最为重要、最为基本的研究领域。文中采用密钥协商建立节点间的会话密钥,通过更新簇密钥实现会话密钥的实时更新,提出一种基于椭圆曲线密码体制(ECC)的轻量级密钥管理方案(LWKM)。仿真结果表明,与传统的密钥管理方案相比,LWKM方案具有更高的网络连通性、可扩展性和安全性及更低的资源开销。The design of secure and reliable key management schemes and protocols is one of the most important aspects and basic research field of secure wireless sensor networks. In this paper, a lightweight key management scheme (LWKM) based on elliptic curve crypto-system (ECC) is proposed. The session key between nodes is established by key negotiation. The real-time update of session key is realized by updating the cluster key. Simulation results show that LWKM scheme has higher network connectivity, scalability, security and lower resource overhead the traditional key management schemes.
