Landis+Gyr has selected Seal SQ’s Ines public key infrastructure (PKI) tool to provide 30 million digital certificates for smart meters being deployed in the Asia Pacific region starting this summer.

Swiss firm Seal SQ develops and sells semiconductors, PKI and post-quantum hardware and software products. It is partnering with Landis+Gyr, a smart grid and energy management technology company, to provide utilities with a flexible PKI offering.

The Ines PKI provides robust, FIPS-certified digital certificates to ensure the security and integrity of an extensive smart meter network. These certificates are essential for authenticating devices, securing communications and protecting against cyber threats in an increasingly connected energy ecosystem. The scope of this deployment – 30 million certificates – underscores Seal SQ’s ability to deliver scalable, compliant and cost-effective security for large IoT deployments.

Landis+Gyr’s global security offerings include on-premises and hosted services for data encryption, network certificates and threat monitoring.

In addition to this PKI agreement, Landis+Gyr and Seal SQ have collaborated on European projects including security for over one million gas meters annually in the UK. These security elements, combined with Ines-managed PKI services, ensure compliance with local regulations and provide end-to-end security for Landis+Gyr’s smart metering.
