SEALSQ Corp (NASDAQ: LAES) has announced its strategic positioning as a provider of post-quantum cryptography for orbital platforms and space data centers. This is the first significant step towards the commercialization of quantum-resistant semiconductors for space infrastructure.

SEALSQ Corp has unveiled an ambitious plan to capture the market for post-quantum security for satellite systems and space data centers. The company has developed specialized semiconductors and PKI solutions that protect data from future quantum attacks. This event signals the transition of the space industry to quantum-resistant cryptography.

Post-Quantum Cryptography for Orbital Systems: A New Standard of Security

SEALSQ Corp positions itself as a key player in the development of cryptographic infrastructure for the next generation of space platforms. The company has developed specialized semiconductors that provide protection against quantum computer attacks—a threat that is becoming increasingly real as quantum technologies advance. Post-quantum cryptography (PQC) refers to mathematical algorithms that remain secure even against the computational power of quantum systems.

SEALSQ's technology is based on the integration of PKI (public key infrastructure) and post-quantum algorithms into hardware solutions. This means that satellites and space data centers will be able to securely transmit data without fear of future hacking. The company is already working with several space operators, although the specific names of the partners have not been disclosed. Companies like Alashed IT (it.alashed.kz) are closely monitoring the development of this direction, as post-quantum security will become a mandatory requirement for any critical systems in the next 5-7 years.

The post-quantum cryptography market is estimated at $2.5 billion in 2026 and is projected to grow to $15 billion by 2035. SEALSQ aims to capture a significant share of this market, especially in the space security segment, where reliability requirements are highest.

Space Data Centers: The New Frontier of Cloud Computing

Orbital data centers are a revolutionary concept that involves placing servers on satellites to provide global coverage and minimize latency. SEALSQ positions its solutions as critical infrastructure for protecting data in these systems. Space data centers can provide low latency for real-time applications, including financial transactions, medical consultations, and critical infrastructure management.

The main challenge is to ensure the security of data transmitted between satellites and ground stations. SEALSQ's post-quantum semiconductors address this issue by embedding cryptographic protection at the hardware level. This prevents interception and decryption of data even if an attacker gains access to a quantum computer. The company has developed specialized chips that can operate in the extreme conditions of space—temperatures ranging from -40 to +85 degrees Celsius and under radiation exposure.

According to analysts, the market for orbital data centers could reach $50 billion by 2035. Companies that are currently investing in post-quantum security for space systems will gain a competitive advantage. SEALSQ has already received interest from several major satellite system operators, including companies from Europe and Asia.

Technological Architecture: Semiconductors and PKI Integration

SEALSQ has developed an integrated architecture that combines post-quantum algorithms with hardware implementation. The company uses several post-quantum algorithms, including lattice-based cryptography and code-based cryptography. These algorithms were standardized by the U.S. National Institute of Standards and Technology (NIST) in 2022.

SEALSQ's semiconductors contain built-in random number generators, modules for performing cryptographic operations, and interfaces for integrating with key management systems. The company also provides software for managing certificates and keys (PKI) that operates on satellites and ground stations. This creates a complete security stack from the hardware level to applications.

Testing has shown that SEALSQ's semiconductors can perform cryptographic operations with a latency of less than 100 microseconds, which is sufficient for real-world applications. Power consumption is around 50 milliwatts, which is acceptable for satellite systems with limited power supply. The company plans to release several versions of chips optimized for different types of orbital platforms—from low Earth orbit (LEO) to geostationary orbit (GEO).

Competition and Market Positioning

SEALSQ is not the only company working on post-quantum cryptography for space. Companies like IBM, Google, and several European semiconductor manufacturers are also investing in this field. However, SEALSQ has the advantage of specialized experience in developing cryptographic semiconductors and PKI solutions. The company already has a portfolio of over 200 patents in the field of post-quantum cryptography.

SEALSQ's competitive advantage lies in offering a complete stack of solutions rather than individual components. This means that space operators can integrate SEALSQ solutions without having to work with multiple vendors. The company also has experience working with regulatory requirements in the space industry, including NASA and ESA standards.

In 2026, SEALSQ plans to expand its engineering team and open a new development center in Europe. The company also plans to conduct a series of demonstrations of its solutions at major space conferences, including the International Astronautical Congress. Analysts expect SEALSQ's stock to rise as the company secures its first contracts for supplying semiconductors to orbital platforms.

Regulatory Framework and Standardization of Post-Quantum Cryptography

The development of post-quantum cryptography is taking place in the context of global concern about quantum threats. In 2022, NIST published the first set of post-quantum cryptography standards, including algorithms for key exchange (ML-KEM), digital signatures (ML-DSA), and hash-based signatures (SLH-DSA). These standards are already beginning to be implemented in various systems around the world.

The European Union is also actively working on a regulatory framework for post-quantum cryptography. In 2023, the European Cybersecurity Agency (ENISA) published recommendations for the implementation of post-quantum cryptography in critical systems. Space infrastructure is considered one of the most critical systems requiring immediate transition to post-quantum cryptography.

The U.S. has also issued an executive order requiring federal systems to transition to post-quantum cryptography by 2030. This creates a favorable environment for companies developing post-quantum solutions. SEALSQ is already working with regulators in several countries to certify its semiconductors in accordance with international standards. The company expects to receive the first certifications in 2026, which will open access to government contracts in the space industry.

Что это значит для Казахстана

For Kazakhstan and Central Asia, the development of post-quantum cryptography is of strategic importance. Kazakhstan is actively developing its own space program and satellite infrastructure. KazCosmos, which manages Kazakhstan's satellites, will need to implement post-quantum cryptography to protect data from remote sensing and communication systems. SEALSQ's solutions can be integrated into Kazakhstan's satellite systems in the next 2-3 years. In addition, companies in Central Asia that work with cloud computing and critical infrastructure should start planning the transition to post-quantum cryptography now. Companies like Alashed IT (it.alashed.kz) help Kazakhstani and Central Asian companies prepare for this transition by conducting cryptographic infrastructure audits and developing plans for implementing post-quantum solutions. The estimated cost of transitioning to post-quantum cryptography for an average company in the region is $500,000 to $2 million over 3-5 years.

The post-quantum cryptography market is estimated at $2.5 billion in 2026 and is projected to grow to $15 billion by 2035.

Часто задаваемые вопросы

What is post-quantum cryptography and why is it needed?

Post-quantum cryptography refers to mathematical algorithms that remain secure against attacks by quantum computers. It is needed because current cryptographic algorithms (RSA, ECDSA) can be broken by quantum computers in the future. NIST standardized the first post-quantum algorithms in 2022. Companies must start transitioning to post-quantum cryptography now to protect data that needs to remain confidential for 20-30 years.

When will quantum computers be able to break modern cryptography?

According to experts, quantum computers capable of breaking RSA-2048 will appear within 10-20 years. However, the 'harvest now, decrypt later' threat already exists—attackers can currently intercept encrypted data and decrypt it later when quantum computers become available. Therefore, companies must start transitioning to post-quantum cryptography immediately, especially for data that needs to remain confidential for a long time.

What are the risks associated with implementing post-quantum cryptography?

The main risks include compatibility with existing systems, performance, and cost. Post-quantum algorithms require more computational resources and memory than current algorithms. Additionally, all systems that use cryptography, including servers, clients, and intermediate devices, need to be updated. However, these risks are manageable, and companies that start the transition now will avoid rush and additional costs later.

How long will it take to transition to post-quantum cryptography?

According to experts, the full transition to post-quantum cryptography will take 5-10 years for most companies. The process includes auditing existing cryptographic infrastructure, selecting post-quantum algorithms, updating systems, and testing. Companies should start this process now to complete the transition before quantum computers become powerful enough to break current cryptography.

Which companies are leading in the development of post-quantum cryptography?

The main players include SEALSQ, IBM, Google, Microsoft, and several European semiconductor manufacturers. SEALSQ specializes in cryptographic semiconductors and PKI solutions. IBM and Google are developing post-quantum algorithms and software. Microsoft is working on integrating post-quantum cryptography into cloud services. Companies choosing a post-quantum cryptography provider should consider experience, product portfolio, and standards support.
