Post-Quantum Security Spurs National Sovereignty Thinking

This article examines how recent U.S. AI export controls have exposed critical dependencies in post-quantum cryptography (PQC) migration, forcing governments and CISOs to confront the issue of "quantum sovereignty." The core concern is that many nations' PQC strategies rely on a concentrated set of vendors and standards (like those from NIST) that are subject to foreign jurisdiction, creating a risk of sudden disruption. The article outlines how different regions are responding: the U.S. and EU are setting binding deadlines and regulations, Canada and India are pursuing domestic capability development, Singapore is mandating vendor dependency management for financial institutions, and China is developing its own independent PQC standards. Ultimately, the piece argues that true cryptographic agility requires not just quantum-resistant encryption, but also the ability to control and switch the vendors and supply chains that implement it.
