摘　　要：针对智能电网高级量测体系(advanced metering infrastructure,AMI)中智能电表与配电自动化系统、分布式电源监控系统等通信过程中可能存在的信息安全问题,提出了一种计及多端互联通信的智能电网AMI新型密钥管理方案.首先基于电力系统IEC 61850标准建立了智能电表量测信息交互模型,然后根据AMI在电力系统中的密钥实际管理需要,提出了一种适用于AMI环境下的密钥管理架构,并采用数据-密钥双向动态更新策略,降低了网络密钥分发耗损与泄漏风险.通过算法安全性和性能测试可知,该新型密钥管理方法符合电力系统数据量测的安全需要,能够有效保障智能电网AMI中多端互联通信过程中的信息安全.This paper proposed a new key management scheme for advanced metering infrastructure(AMI) of smart grid with multi-terminal interconnection communication to address the possible information security problems in the communication between smart meters and distribution automation systems and distributed power monitoring systems in smart grid AMI.Then,according to the actual key management needs of AMI in the power system,a key management architecture was proposed for AMI environment,and the data-key bi-directional dynamic update strategy was adopted to reduce the risk of network key distribution depletion and leakage.The algorithm security and performance tests showed that the new key management method proposed in this paper meet the security needs of data volume measurement in power system,can effectively guarantee information security in the process of multi-terminal interconnection communication in smart grid AMI.
