Global Quantum-Resistant Cryptographic Mandate & Infrastructure Overhaul

The impending maturation of fault-tolerant quantum computing represents a systemic threat to the foundations of modern digital security. Current public-key cryptography standards—including RSA and Elliptic Curve Cryptography (ECC)—rely on mathematical problems (integer factorization, discrete logarithms) that are exponentially difficult for classical computers but provably solvable by sufficiently powerful quantum algorithms, notably Shor's algorithm. The estimated timeline for this capability has shifted from theoretical conjecture to an imminent engineering challenge, establishing what analysts term the 'Cryptographic Cliff.' This mandates a global, mandatory migration to Post-Quantum Cryptography (PQC) standards across all domains of critical infrastructure.
