Electricity meter and system hardened against attack vectors

Abstract

An electricity meter and electricity system or grid that is hardened against attack vectors is described, and provided in part by automated multiple-factor authentication over multiple communication networks. In an example, a utility company may control an advanced metering infrastructure (AMI) network to provide internal communications. Metering devices may utilize customer's Wi-Fi to gain access to the internet, allowing electricity consumption data to be transmitted over the internet. Multiple authentication factors are used to prevent a bad actor from impersonating the metering device or cloud server. In an example, each metering device determines a secret, and sends the secret over the AMI network to a utility company server, and which relays the secret to the cloud server. The cloud server uses the secret to establish trust with metering devices. Additionally, the metering devices and the cloud server have signed certificates, which are used in additional authentication processes.
