WISeKey’s WISeSat.Space Brought Together Global Thought-Leaders to Davos

WISeKey International Holding Ltd (“WISeKey”), a global leader in cybersecurity, blockchain, and IoT, recently hosted its Quantum Security Space Roundtable during the WISeKey Davos 2026 program. The event convened experts from defense, space, quantum technologies, and cybersecurity sectors to tackle one of the space industry’s most pressing challenges: safeguarding space infrastructure in the post-quantum era.

As quantum computing progresses rapidly, traditional cryptographic systems like RSA and ECC face growing vulnerabilities. These weaknesses threaten satellite communications, command-and-control networks, and space-based data. Consequently, post-quantum space security aims to shield satellites and orbital systems using quantum-resistant cryptography (PQC), ensuring long-term protection against future quantum threats.

Key Areas of Post-Quantum Space Security

Firstly, satellite security is evolving as new platforms incorporate post-quantum cryptographic measures. Hybrid methods, such as Triple Key Encapsulation Mechanisms (KEMs), combine PQC with elliptic-curve cryptography to protect satellite-to-ground communications. Secondly, threat mitigation is critical because quantum computers could compromise today’s encryption, making PQC essential to safeguard sensitive data and sovereign space assets. Thirdly, hardware-anchored trust is gaining importance as quantum-resistant semiconductors provide secure identities, authentication, and tamper-proof operations in orbit. Finally, operational constraints demand optimized PQC algorithms that function efficiently under limited processing power, bandwidth, and latency conditions.

Recent Developments

WISeKey achieved a major milestone in late 2025 by successfully testing post-quantum cryptography on satellites, marking a pivotal step toward quantum-ready space operations. A fully operational WISeSat PQC satellite is scheduled for launch in Q2 2026. Meanwhile, NIST’s standardization of PQC algorithms accelerates industry adoption, complemented by training programs for defense and space infrastructures. Hybrid cryptographic systems further provide protection during the transition from classical to quantum-resistant models.

Roundtable participants emphasized that quantum computing will fundamentally disrupt traditional space security models. Colonel Ludovic Monnerat of the Swiss Armed Forces highlighted that quantum-resilient identity and secure satellite operations are vital for national security. Benjamin Guyot, CEO of SpaceTalk, stressed end-to-end authentication and cryptographic agility as essential for maintaining trust in commercial and government space networks.

Mohammed Aboul-Magd, VP at SandboxAQ, urged immediate deployment of post-quantum security to protect long-lived space systems. Emile de Rijk of SWISSto12 noted that next-generation satellites must embed security from design to payload. Jonathan Cirtain, President of Axiom Space, underlined the need for trusted identities in human spaceflight and orbital services. Luc Piguet, CEO of ClearSpace, emphasized secure, authenticated systems as the foundation for safe in-orbit operations. Grégoire Ribordy of ID Quantique added that quantum key distribution complements PQC in protecting satellite communications. María Pía Aqueveque Jabbaz highlighted layered, interoperable architectures as key to sovereignty in the quantum era.

“The space domain is rapidly becoming the backbone of our digital and geopolitical infrastructure,” said Carlos Moreira, Founder and CEO of WISeKey. “This roundtable made clear that quantum-ready security, trusted digital identity, and hardware-anchored trust must be embedded into space systems from day one to ensure resilience, sovereignty, and long-term mission success.”

Concluding the WISeKey Davos 2026 Quantum Space Roundtable, experts agreed that quantum readiness is no longer optional. Governments, operators, and industry leaders must act immediately to secure satellites, ground systems, and space-based identities against the imminent quantum disruption.
