The Global Mandatory Utility Layering of Post-Quantum Cryptography

The implementation of quantum-resistant cryptographic standards—collectively termed Post-Quantum Cryptography (PQC)—represents a mandatory, foundational infrastructural overhaul for global digital systems. Driven by the documented threat posed by fault-tolerant quantum computers, which possess the computational power to break widely used public-key algorithms such as RSA and Elliptic Curve Cryptography (ECC), this systemic transition is viewed not merely as an upgrade but as a critical utility service necessary to maintain trust in all networked operations. The anticipated advent of cryptographically relevant quantum computing necessitates preemptive, global action to prevent the 'Harvest Now, Decrypt Later' attack vector from compromising historical and real-time data streams across every sector.
