The Role Of Governments In Promoting Post Quantum Cryptography

The real story of the role of governments in promoting post quantum cryptography is far weirder, older, and more consequential than the version most people know.

The past decade has seen a surge of interest and investment in the development of post-quantum cryptography (PQC) - cryptographic algorithms that can withstand the powerful decryption capabilities of future quantum computers. But the story of how governments have played a central role in driving this critical technological shift is far more complex, and has much deeper roots, than most people realize.

The Quantum Computing Threat

In the 1990s, computer scientists like Peter Shor made a startling discovery: quantum computers, if they could be built, would possess the ability to rapidly crack the encryption algorithms that underpin the modern internet and secure communications. This "quantum computing threat" sent shockwaves through the national security and intelligence communities of the world's major powers.

Governments like the United States, China, and Russia quickly recognized the urgent need to develop new forms of encryption that could resist the decryption capabilities of quantum computers. This set off a high-stakes global race to advance the field of post-quantum cryptography (PQC).

The National Security Imperative

For national security agencies, the need to migrate to PQC algorithms was a matter of the highest priority. Classified communications, intelligence gathering, weapons systems, and critical infrastructure all relied on encryption methods that would be vulnerable to quantum attacks. The prospect of adversaries being
