摘　　要：信息安全问题是智能电网高级量测体系(advancedmetering infrastructure,AMI)建设必须解决的一个关键问题。文章首先深入分析了AMI通信系统结构、应用环境和信息安全风险,提出了基于开放标准实现AMI通信系统快速部署的技术建议;然后针对智能电表等嵌入式设备计算和存储资源受限的情况,引入了包含可信第3方密钥管理中心的Blom密钥协商机制,并进行了安全性分析;最后针对AMI应用数据的机密性和完整性保护需求,给出了基于对称密码的数据保护方案。In the construction of advanced metering infrastructure（AMI） for smart grid the information security is a key problem to be paid special attention to.Firstly,the system structure,application environment and information security risk of AMI are analyzed in depth,and based on open standard some technical suggestions to implement rapid deployment of AMI communication system are proposed.Secondly,in allusion to the situations that the computing and storage resources for embedded devices such as smart meters and so on are restricted,the Blom key agreement mechanism,in which the trust third party key distribution center（KDC） is included,is led in and corresponding security analysis is performed.Finally,according to the requirement for ensuring data confidentiality and integrity a data protection scheme based on symmetric cipher is given.
