What Happened

Post-Quantum Security Becomes Procurement Priority

Satellites built today must outlive the encryption protecting them, as their operational lifespan can extend into the 2040s. The current encryption used in satellites may not remain secure over such a long period, especially with the advent of quantum computing. This has led to a focus on post-quantum security, with companies like Quantum Secure Encryption Corp. working on solutions. The European Space Agency is also moving forward on this issue, with demonstrations showing that quantum-safe security can be implemented on existing satellite infrastructure. This development was reported by Equity Insider.
