摘要：The Advanced Metering Infrastructure (AMI) is an essential part of the smart water grid. One of the daunting challenges in realizing the services in the AMI system is the security issue. In this paper first we investigate the AMI communication system, and then address security requirements for water meters in the AMI system. We point out the distinguished features of the water meter compared to the smart meter. Then, we address the issues for developing the water meter in three aspects: key distribution, deployment and implementation. Finally, we propose security measures that we take in developing security modules for the smart water meter to meet these requirements.
