摘　　要：由于智能电网高安全性、低数据传输延时的需求及部分应用环境资源受限的特点,其密钥管理有着更高的要求,以保证认证、加密等安全技术的可靠使用,进一步增强智能电网数据传输安全.在深入分析在高级量测体系(AMI)中应用的开放式智能电网协议(OSGP)特点和安全需求的基础上,提出了一种基于椭圆曲线密码技术(ECC)的轻量级密钥管理方案,实现数据集中器和智能电表之间的密钥分发和管理.理论分析和实验结果表明,该方案具有很强的安全性、可靠性、灵活性及很高的效率,能很好地适应智能电网部分应用环境资源受限的特点,能有效满足智能电网数据传输实时性高的要求.Because smart grid needs high security, low delay of data transmission, and some of its application environments are resource-limited, key management in smart grid has higher request, to guarantee reliable use of some security technologies such as authentication, encryption, etc, furthermore, to strengthen the security of smart grid. On the basis of deeply studying the traits and security requirements of Open Smart Grid Protocol （ OSGP） which is applied in Advanced Metering Infrastructure （AMI） ,in this paper, we present an Elliptic Curve Cryptography （ECC） based light-weight key management solution, to realize the key distribution and management between data concentrator and smart meters. Theory analysis and experiment results show that this solution is very secure, reliable, flexible and efficient. It adapts resource-limited environments in smart grid very well, and effectively satisfies the instantaneity of data transmission for smart grid.
