SEALSQ Advances Post Quantum Security for Space Based AI and Data Centers SEALSQ outlined a plan to supply post-quantum secure semiconductors and cybersecurity infrastructure for orbital platforms and space-based data centers aimed at AI workloads in space.
The company is targeting quantum-resistant encryption, trusted hardware identity, secure satellite communications, and long-life, low-power chips to support autonomous orbital AI and sovereign cloud architectures.
SEALSQ filed a patent application for a protection technique against side-channel attacks on cryptographic algorithms, focused on strengthening hardware security for post-quantum cryptography implementations.
These developments indicate that SEALSQ is positioning itself around post-quantum security as a core capability, with an emphasis on applications in space-based AI and sovereign cloud infrastructure where long operating lifetimes and secure communication are critical.
For investors, the expanding intellectual property around side-channel attack protection and PQC hardware may be important to monitor, particularly as major platforms, including Android and Chromecast devices, move toward broader post-quantum cryptography adoption. Announcement • Apr 30
Sealsq Corp Announces New Patent Application for Protection Technique Against Side-Channel Attacks on Polynomial Cryptographic Algorithms SEALSQ Corp. had announced the filing of a new patent application for an innovative protection technique against side-channel attacks on polynomial cryptographic algorithms. This development further strengthens the Company’s robust intellectual property portfolio at the exact moment Google has set a firm 2029 deadline for full post-quantum cryptography migration across its ecosystem. The patent introduces a novel solution at the message encoding stage of polynomial-based PQC algorithms (such as NIST-standardized ML-KEM/Kyber). It hardens hardware implementations against side-channel attacks that exploit power consumption, electromagnetic emissions, or timing variations, a critical vulnerability even for mathematically robust post-quantum algorithms. The invention covered by this patent application represents a separate and complementary line of research, developed in parallel with the QS7001 program. It illustrates SEALSQ’s broader commitment to continuously advancing the state of the art in PQC hardware security — both for current products and for future generations of secure components. This latest patent filing coincides with the sampling phase of SEALSQ’s QS7001 Quantum Shield secure element — the Company’s first native post-quantum secure microcontroller. The QS7001 already embeds NIST-approved PQC algorithms (ML-KEM/Kyber and ML-DSA/Dilithium) directly in silicon, delivering a tamper-resistant hardware root of trust for secure boot, device authentication, TLS handshakes, and certificate management. SEALSQ’s complete quantum-resistant ecosystem, which combines PQC-secure semiconductors, the INeS PKI platform, and cryptographic agility services, aims to enable OEMs to achieve smooth, low-disruption, and certifiable migration (Common Criteria EAL5+ and beyond) ahead of the 2029 deadline. With 126 active patents and more than 1.75 billion secure semiconductors deployed worldwide, SEALSQ believes it is well positioned to support device manufacturers and the Android/IoT ecosystem in meeting both the immediate market demand and the highest standards of physical and quantum security.
