A Novel Non-cryptographic Security Services for Advanced Metering Infrastructure in Smart Grid

Advanced metering infrastructure (AMI) is an architecture for automated, two-way communication between a smart utility meter and a utility company. It is responsible for collecting all the data and information from the loads and consumers. These data and information are critical as it threats the reliability of electrical energy delivery and consumers' privacy. Traditional security solution rely on public key infrastructure may not suitable due to the scalability of the electric grid. In this paper, the author presents a noncryptographic approach for providing confidentiality, integrity, and authentication (CIA) for AMI. The methods presented in this paper based on the hardware and physical layer approach. A basic idea of the integrity and authentication techniques is to use physical unclonable function (PUF), while the confidentiality technique is based on channel status information of wireless channel between the AMI subsystems. Our approach is secure and efficient for large scale network. General Terms Security, Protocols.
