SEALSQ Quantum
SEALSQ Corp is a well-known company in the semiconductor and post-quantum cryptography (PQC) industries. As a division of WISeKey International Holding Ltd, SEALSQ focusses on the creation and marketing of innovative Post-Quantum technology hardware and software, semiconductors, and Public Key Infrastructure (PKI). Developing innovative quantum-resistant semiconductors and cryptography is the company’s primary strategic focus. These products are made especially to meet the urgent security issues brought on by the quick development of quantum computing.
The Quantum Threat and SEALSQ’s Response
Traditional cryptographic methods like RSA and ECC underpin current digital security, but powerful quantum computers are becoming more capable of exploiting them. These well-established encryption approaches are challenged by quantum computers’ ability to solve their complex mathematical problems, which would threaten data integrity and privacy worldwide.
In reaction to this imminent quantum threat, SEALSQ is leading the way in the creation of Post-Quantum Semiconductors that offer strong, long-lasting security for private information. Directly integrating post-quantum cryptography algorithms into satellite hardware is the strategy used by SEALSQ. This cutting-edge technique guarantees that cryptographic operations are separated from vital systems, greatly improving security and reducing vulnerabilities.

Secure key generation, distribution, and administration are also made easier by this architecture, which is crucial for reliable data transfer between satellites and ground stations. Assuring worldwide interoperability and adherence to new security protocols, the cryptographic algorithms being tested on board these satellites are in line with the most recent standards being developed by the National Institute of Standards and Technology (NIST) in the United States.
Numerous vital industries and applications are targeted by SEALSQ’s quantum-resistant technologies, including:
- Authentication tokens with many factors.
- Energy-smart systems.
- Systems of Medicine and Healthcare.
- Defence.
- The infrastructure of the IT network.
- Cars.
- Automation and Control Systems for Industry.
SEALSQ protects vital systems and improves resilience across a range of industries by integrating Post-Quantum Cryptography into its semiconductor products, ensuring that companies are safe from quantum assaults.
Recent Satellite Launch News and Innovations
SEALSQ is leading the way in quantum-resilient space security with to agreements with SpaceX and WISeSat AG. Several projects reached milestones in 2025:
- On January 14, 2025, SEALSQ Corp, SpaceX, and WISeSat AG launched the first of six next-generation satellites planned for 2025. This was launched from California’s Vandenberg Space Force Base. Advanced post-quantum encryption and secure communication technologies are incorporated into the architecture of these satellites, enabling a scalable and secure satellite constellation for machine-to-machine (M2M) communication. This initiative uses Satellite-as-a-Service to provide strong Internet of Things solutions for critical infrastructure, logistics, and precision agriculture without big upfront infrastructure costs.
- On June 23, 2025, SpaceX’s Falcon 9 Transporter-14 launched WISeSat 3, the latest satellite, from Vandenberg, California. The latest rollout was essential. Decentralised infrastructure and space-based cybersecurity have advanced significantly as a result of this project. The first satellite to include SEALSQ’s Quantum RootKey was WISeSat 3.

Decentralised Physical Infrastructure Network (DePIN) from Orbit
Beyond ensuring secure communications, the WISeSat 3 mission deploys the first Decentralised Physical Infrastructure Network (DePIN) from orbit in history. This invention has the potential to revolutionise the function of satellites in safe digital identity and decentralised banking. Cutting-edge technology, developed in partnership with Hedera, is integrated into the new satellite to facilitate SEALCOIN token exchanges straight from orbit. Overseeing the development of the SEALCOIN platform, SEALCOIN AG, a subsidiary of WISeKey, is dedicated to the decentralised physical internet utilising DePIN technology.

“This launch is not only a milestone for decentralised infrastructure in space, but also a strategic move towards making space communications quantum-resilient,” said Carlos Moreira, founder and CEO of WISeKey (and SEALSQ), highlighting the importance of the launch further. By integrating PQC and facilitating blockchain-based tokenisation from orbit, the changing the way that space technology, cybersecurity, and finance interact. Board Director David Fergusson of WISeKey added his thoughts on WISeSat’s revolutionary PQC innovation, pointing out that it helped establish a standard for reliable data transfer and communication in the future.
Strategic Impact and Future Outlook
Designed to provide sovereign, secure, and scalable satellite services for digital identification, IoT, and trustworthy data transmission, these satellite launches are a part of the expanding WISeSat constellation. The enhancement of Europe’s space and cybersecurity capacities, the advancement of technological independence, and the establishment of leadership in the rapidly developing field of quantum computing all depend on this coordinated effort. In order to create a quantum-resistant security infrastructure in orbit, SEALSQ and its partners are combining PQC capabilities and pioneering DePIN from space. This will improve secure data transmission and create new opportunities for decentralised applications that can be run directly from space.
