Cyber Security of Smart Meters in AMI of Smart Grids
摘要
An electrical grid is said to be smart if it uses smart devices with advanced technologies for transport of electricity from the generating side to the end users to meet their electricity demand. A smart grid is a combination of the conventional electrical grid, the communication module, and the supporting information infrastructure. Advanced Metering Infrastructure or AMI is the mainstay of the smart Grid. Smart meters and related sub-systems that form the AMI architecture have two important roles. (1) One is the access to more granular interval usage data; (2) Second is the durable bidirectional communication link, to deliver messages/instructions to the meter. The AMI infrastructure provide the meter reading data on an hourly or sub-hourly basis. However the data privacy of the AMI is of prime concern for both the utility and the end user.
