: Unlike PQC, QKD requires specialized fiber-optic hardware and "trusted nodes," making it expensive and difficult to scale for the general internet. 3. The Human and Process Leap
: Using machine learning to detect anomalies at speeds impossible for human analysts, countering AI-powered "polymorphic" malware. Summary of the Transition Traditional Security Quantum-Resistant Security Mathematical Basis Factoring large numbers Lattice, Isogeny, or Code-based math Primary Threat Brute force/Classical hacking Quantum computing (Shor's Algorithm) Security Type Computational (Hard to solve) Information-Theoretic (Laws of physics) Do We Need Quantum Leaps in Security?
: This is a "leap" in agility; organizations must move toward crypto-agility , allowing them to swap out compromised algorithms without rebuilding entire systems. 2. Quantum Key Distribution (QKD) : Unlike PQC, QKD requires specialized fiber-optic hardware
The current security infrastructure relies on mathematical problems (like RSA and ECC) that are easy for classical computers to solve but would be trivial for a sufficiently powerful quantum computer using . This creates a "Harvest Now, Decrypt Later" threat, where adversaries steal encrypted data today to unlock it once quantum technology matures. 1. Post-Quantum Cryptography (PQC) This creates a "Harvest Now, Decrypt Later" threat,
Security is rarely just a technical problem. A "quantum leap" is also required in how we manage data lifecycle:
: Moving away from "perimeter" security to a model where no user or device is trusted by default, regardless of their location.
