Post-quantum cryptography adoption and the national security implications

Quantum computers are progressing from theoretical to real threats against asymmetric cryptography like RSA and ECC, though experts disagree on timelines (RSA says far off; Google suggests as soon as 2029; researcher Filippo Valsorda urges taking the risk seriously). Because quantum access will likely remain restricted to governments and large corporations, post-quantum cryptography (PQC) adoption will disproportionately benefit nation-state actors over cybercriminals, since harvest-now-decrypt-later attacks primarily threaten confidentiality rather than causing direct financial damage. This creates a national security gap: well-resourced targets like governments and banks will adopt PQC quickly, while under-resourced critical infrastructure (municipal utilities, small hospitals, local emergency services) will lag, leaving them exposed to attacks similar to Salt Typhoon. NIST has already published PQC standards (FIPS 203-205), and Executive Order 14412 pushes faster federal adoption. Proposed solutions include government mandates, compliance requirements (PCI DSS, ISO 27001), default PQC in cloud/TLS/software libraries, prioritizing critical systems, executive awareness, and expanded university curricula.
