Smart Energy

Smart energy systems rely on trusted devices, secure communications, and long-term resilience.

From smart meters to grid infrastructure, each connected device must authenticate securely, protect sensitive data, and operate reliably over lifecycles that can exceed 15 years.

SEALSQ provides a vertically integrated security approach combining secure semiconductors and PKI-based trust services, ensuring end-to-end protection across the smart energy ecosystem — today and in preparation for the next generation of cybersecurity challenges.

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.

Building Secure Smart Grids Today

Smart meters and grid-connected devices form the foundation of modern energy networks. As deployments scale to millions of units, ensuring device identity, data integrity, and secure lifecycle management becomes critical.

SEALSQ enables this with:

Hardware-based security through secure elements that protect cryptographic keys and enforce trusted execution
PKI and certificate lifecycle management to authenticate devices and secure communications across the network
End-to-end security architecture from manufacturing to field operation

This approach ensures that utilities can deploy and operate smart energy infrastructure with confidence, at scale.
