Ensure complete smart meter life-cycle security

This application note explores the various potential points of attack in the life cycle of smart meters: during manufacturing, installation, operation, and post-installation. The application note then discusses real solutions to these security vulnerabilities, such as the use of secure bootloaders during manufacturing, metrology boards during installation, asymmetric encryption in the hardware rather than the software during operation, and possibly a cumulative attestation kernel (CAK) for forward-looking security. Maxim's ZEUS system-on-chip (SoC) is presented as a robust design solution for smart meter security.
