Quantum Cryptography and Security

SEALSQ Post-Quantum PKI (Nov 24, 2025): Cybersecurity firm SEALSQ announced it will launch a U.S.-based post-quantum “Root of Trust” service. The system will issue quantum-resistant digital certificates and cryptographic keys compliant with NIST and NSA CNSA 2.0 standards. This U.S.-hosted PKI will help enterprises and government agencies secure IoT, telecom, cloud and satellite assets against future quantum-computer attacks. According to theQuantumInsider, SEALSQ’s service (go-live in late 2025) will enable a fully domestic post-quantum encryption lifecycle for devices and networks in critical sectors.

Satellites and Post-Quantum Encryption (Nov 24, 2025): Help Net Security published an interview with Col. Ludovic Monnerat (Swiss Space Command) on the impact of quantum threats on satellites. Monnerat emphasized that legacy satellite links relying on RSA/ECC are “especially vulnerable” to future quantum adversaries. He noted that moving to post-quantum algorithms increases computational and bandwidth demands on satellites. Swiss space authorities expect the industry to adopt NIST’s new quantum-resistant standards and “zero trust” principles in satellite systems. The interview underscores a growing need for “quantum-safe” encryption in space architectures before quantum computers are powerful enough to break today’s ciphers.
