[{"type":"text","content":"Geneva, Switzerland, May 09, 2025 (GLOBE NEWSWIRE) -- SEALSQ Corp (NASDAQ: LAES) (\"SEALSQ\" or \"Company\"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, together with WISeKey International Holding Ltd (SIX: WIHN, NASDAQ: WKEY) and WISeSat.Space AG, today announced that on June 2025 will launch the WISeSat 2.1, the first satellite embedding SEALSQ’s WISeKey Quantum RootKey as part of a space-based Quantum Key Distribution (QKD) Proof-of-Concept. This launch marks a breakthrough in protecting satellite communications from quantum-enabled cyberattacks and confirms SEALSQ’s leadership in securing critical space and terrestrial infrastructure using post-quantum technologies. The WISeKey Quantum RootKey is a hardware-based root-of-trust technology, designed to resist quantum decryption attacks by securing key generation, storage, and management directly on the satellite. This ensures that sensitive cryptographic operations remain isolated, tamper-resistant, and protected against both classical and quantum threats. Leveraging NIST-recommended post-quantum algorithms such as CRYSTALS-Kyber and CRYSTALS-Dilithium, the RootKey enables end-to-end secure authentication, encryption, and data integrity, even under the computational power of future quantum computers. The deployment of this technology in WISeSat 2.1 enables several critical applications: Allows secure command authentication to prevent spoofing or unauthorized control of satellites.Protects sensitive data such as Earth observation imagery, defense communications, and scientific measurements during transmission to ground stations.Supports the secure distribution of cryptographic keys to protect critical infrastructure, including energy, transportation, and smart city systems.Enables trusted onboarding of billions of IoT devices worldwide, even in remote or disconnected regions, by delivering quantum-resistant cryptographic identities from space. As nation-states and threat actors advance quantum computing capabilities, satellites face increasing risks of key extraction, spoofing, and eavesdropping. SEALSQ’s Quantum RootKey defends against these attacks by securely isolating keys, validating all commands with post-quantum signatures, and ensuring that any interception of quantum key exchanges is...
