摘　　要：提出了一种基于ECC和ElGamal的轻量级高安全性密钥管理方案。该方案采用汉密尔顿算法构造密钥池,采用分区域管理模型,每一区域设有一个服务器和控制中心,协议结合ElGamal进行通信双方的会话密钥协商。性能分析和仿真结果表明,该方案与传统的密钥管理方案相比,方案中节点的计算开销和通信开销得到了大大的降低,具有良好的网络连通性,比较适合于无线传感器网络。This paper proposed a lightweight and high security key management based on ECC and ElGamal. In the scheme, the key pool was structured by the Hamilton algorithm, in which a layer network model was given, each lay had a servicer and control center, and session key was generated by ElGamal key agreement. The performance and simulation analysis shows, this scheme is superior to the traditional key pre-distribution schemes, not only computation cost and communication cost could be decreased, but good network connectivity is suitable for wireless sensor networks.
