Smart Energy

Smart energy systems provide better comfort while significantly reducing consumption and environmental footprint. The fast-paced shift to these systems raises new security needs to protect users’ privacy and safety — not just against today’s attacks, but also against tomorrow’s quantum threats.

SEALSQ’s vertically integrated value proposition combines secure semiconductors, PKI-based trust services and post-quantum–ready security to protect smart meters, gateways and grid infrastructure end to end.

The Global Shift to Smart Grids

A smart grid is an electricity network that uses digital and other advanced technologies to monitor and manage the transport of electricity from all generation sources to meet the varying electricity demands of end users. The IOT-based power meter system consists mainly of three main parts, which are remote control, Wi-Fi and theft detection part.

Smart grids usually offer features like real time monitoring, automated outage management and restoration, dynamic pricing mechanisms, and consumer incentive to alter usage during different times of day based on pricing signals. Thus, the smart energy systems provide increased user comfort, sustainability and savings.

For this reason, governments and energy companies across the world are progressively and growingly shifting regulation and power infrastructures towards smart grids, creating a huge market for smart metering devices.

Post-Quantum Security for Smart Grids

As smart grids evolve, their cryptographic foundations must remain secure for decades. Classical algorithms such as RSA and ECC are vulnerable to future quantum computers, threatening the confidentiality of metering data and the integrity of grid controls.

SEALSQ is pioneering post-quantum secure semiconductors for smart energy, embedding NIST-selected PQC algorithms directly into secure hardware and combining them with PKI and trusted provisioning services. This approach helps utilities and device makers deploy smart meters and grid equipment that stay protected against both current and quantum-era attacks.

Securing Smart Grids

Like in any IoT ecosystem, security plays a central role in smart grids: sensors and devices must reliably authenticate with gateways and cloud IT systems, and data must remain encrypted at all times with robust and future-proof cryptography.

Smart meters are therefore an excellent use case for SEALSQ solutions: from VaultIC408 secure elements deployed at scale in smart metering projects, to new post-quantum–ready platforms such as the Quantum Shield QS7001, combined with INeS Managed PKI services and SEALSQ trusted provisioning. This unique vertical integration provides the required security level to comply with local energy market regulations, while offering enough flexibility and scalability for cost-effective, long-term deployments that anticipate quantum-era risks.
