Quantum Security Space Roundtable at Davos

When top global leaders gathered in Davos for the 2026 program, the focus shifted from the earth’s economy to the orbital frontier’s growing challenges. WISeKey International Holding Ltd. hosted a high-level Quantum Security Space Roundtable on 30 January 2026 with defense, space, and cybersecurity thinking leaders. The accord was clear: the post-quantum age is now a realistic necessity for global space infrastructure.

Space Systems’ Impending Vulnerability

The fast development of quantum computing, which poses a danger to the fundamentals of classical cryptography, particularly RSA (Rivest-Shamir-Adleman) and ECC (Elliptic-Curve Cryptography), was the main driving force for the roundtable. As these systems become susceptible, the entire architecture of contemporary space operations, including satellite communications, command-and-control linkages, and sensitive space-based data, is placed at great danger.

To guarantee long-term resilience, post-quantum space security must prioritize the use of quantum-resistant cryptography (PQC), according to participants in the Davos conference. Since satellites cannot be readily retrofitted once in orbit, unlike terrestrial systems, quantum-ready designs must be incorporated from the very beginning of the design process.

Technical Innovations: KEMs and Hardware Trust

To fight these risks, many essential characteristics of post-quantum security were identified. One of the most interesting advancements is the inclusion of hybrid cryptographic techniques, such as Triple Key Encapsulation techniques (KEMs). These hybrid techniques integrate PQC with regular elliptic-curve encryption to protect the essential communications between satellites and ground stations, providing a safety net throughout the transition period between classical and quantum computing.

The program also stressed hardware-anchored trust. Modern space systems rely on quantum-resistant semiconductors for trustworthy identities and tamper-resistant procedures. Implementing these complex algorithms in space is difficult because PQC must be tailored to perform under strict processing power, bandwidth, and latency restrictions.

Strategic and Defense Perspectives

Colonel Ludovic Monnerat, Head of Space Command at the Swiss Armed Forces, gave a critical viewpoint on the strategic relevance of orbital assets for national security. He pointed out that secure command-and-control and quantum-resilient identities are critical for safeguarding sovereign assets in increasingly disputed contexts. This opinion was mirrored by Benjamin Guyot, CEO of SpaceTalk, who described secure satellite communication as the “critical infrastructure” necessary for successful space traffic coordination.

The industrial ramifications were addressed by Emile de Rijk, CEO of SWISSto12, who stated that security must be included at both the hardware and payload levels from the very beginning of a satellite’s lifespan. From a technological aspect, Mohammed Aboul-Magd of SandboxAQ emphasized that because space systems are likely to run for decades, PQC must be installed today to secure data that will still be in transit when quantum computers achieve full maturity.

The Expanding Commercial Space Economy

The group also discussed the new commercial industries. Axiom Space President Jonathan Cirtain spoke on the security needs for both human spaceflight and commercial space stations. He suggested that post-quantum protection is crucial for the burgeoning space economy and in-orbit services.

It’s interesting to note that the conversation turned to the “circular space economy.” The distinction between a useful satellite and a possible hazard becomes solely software-defined as active debris removal and in-orbit servicing expand, according to Luc Piguet, CEO of ClearSpace. Therefore, authenticated and secure systems are the only method to provide safety in a congested orbital environment. Grégoire Ribordy, CEO of ID Quantique, stated that Quantum Key Distribution (QKD) and PQC should be seen as complimentary instruments in this quest.

The Roadmap and Subsidiary Ecosystem of WISeKey

As a major worldwide cybersecurity and IoT provider, WISeKey is at the forefront of this change through its specialist subsidiaries. The business disclosed several significant milestones:

• In late 2025, WiseSat.Space successfully started Proof of Concept (PoC) testing for PQC on satellites.
• In Q2 2026, a fully functional WISeSat PQC satellite is expected to launch.
• The company’s subsidiary SEALSQ Corp. is concentrating on producing post-quantum technology goods and semiconductors.
• Other organizations like WISeKey SA and WISeSat AG offer the essential Root of Trust (RoT) and space-based communication protocols for secure IoT applications.

The “backbone of our digital and geopolitical infrastructure” is quickly evolving into space, according to Carlos Moreira, founder and CEO of WISeKey, who wrapped up the event. He said that the two unavoidable conditions for guaranteeing sovereignty and mission success in the quantum age are hardware-anchored trust and cryptographic agility.

Looking ahead

A request for international collaboration was made at the end of the discussion. Industry leaders now need to concentrate on capacity building and specialized training for space and defense workers, as the National Institute of Standards and Technology (NIST) is speeding up the standardization of PQC algorithms. As María Pía Aqueveque Jabbaz remarked, space is transitioning from a basic “connectivity layer” to a “trust and market layer,” where auditable access and interoperability will determine the winners of the coming decade. For the attendees at Davos 2026, the message was clear: the opportunity to ensure the future of space is open, but it is closing rapidly.
