What Happened

Securing The Future Of Space Communications

The global space economy is expected to expand significantly by 2035, with over 16,000 active satellites in orbit supporting various critical systems. However, the growing threat of quantum computing to current encryption methods has prompted the US government to mandate the adoption of post-quantum cryptography. IBM, in collaboration with Voyager, has successfully demonstrated a quantum-safe communication link between the International Space Station and Earth, using NIST-approved post-quantum cryptography standards. This development was first reported by Unknown Source.
