摘　　要：分析了AMI网络结构和该结构下的安全问题。针对通信供应商提供的安全机制和DL/T698安全机制所存在的问题,本文采用属性基加密的方案解决高级量测体系中的会话密钥管理问题,能够有效解决AMI广播中需要多次加密的问题,并能保障AMI系统信息的私密性,对AMI系统建设有参考意义。Advanced metering infrastructure brings new challenges to power grid. This paper analyzes the AMI network structure and the security issues in this structure of. In order to achieve security under the security mechanisms of Communications providers and security mechanisms of DL/T698, this paper uses attribute - based encryption solutions to address session key management issues in advanced metering infrastructure, which can solve the efficiency problem of many times encryption when primary station broadcast. The issue also protects the confidentiality of AMI. This paper can achieve a reference value to the construction of AMI.

关 键 词：AMI 基于属性加密 网络结构 会话密钥管理
