SEALSQ Post-Quantum Cryptographic Chips Deployed on WISeSat Satellites

SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI and Post-Quantum technology hardware and software products, today announced the integration of its latest post-quantum cryptographic chips on WISeSat satellites. This milestone development underscores SEALSQ’s commitment to securing satellite communications in an era of emerging quantum computing threats. See demo here.

This partnership leverages SEALSQ's cutting-edge semiconductor expertise and WISeSat’s innovative satellite IoT connectivity solutions. With the rise of quantum computing, traditional encryption methods are at risk of being compromised. By converting data into light particles and transmitting it through a constellation of satellites, WISeSat and SEALSQ are pioneering a potential solution to mitigate these future vulnerabilities.

SEALSQ’s post-quantum cryptographic chips serve as essential components for securing devices on these satellites, protecting communications between satellites and ground stations from interception. Historically, satellite communications have been particularly vulnerable to cyber threats due to their transmission through open air, making robust cryptographic protections essential for data integrity and security.

The SEALSQ-manufactured chips are engineered to meet the rigorous demands of post-quantum cryptography, ensuring secure data transmission and resilient device performance, even as quantum computing advances.

WISeSat.Space provides low-earth orbit nanosatellite connectivity, enabling global coverage for IoT devices, including those in remote or underserved regions. This scalable technology supports seamless interconnectivity and expansive IoT ecosystems. To date, 17 WISeSat satellites have been launched via SpaceX, with plans to deploy hundreds more to establish a fully operational quantum-secure communications network. The next WISeSat launch with SpaceX is scheduled for January 14, 2025, from the Vandenberg Space Force Base in California.

This strategic collaboration between SEALSQ and WISeSat represents a significant step towards securing global satellite communications in the quantum era, providing businesses and governments with robust and future-proof connectivity solutions.
