Need Quantum Leaps In Security? — Do We

: Moving away from "perimeter" security to a model where no user or device is trusted by default, regardless of their location.

The most immediate "leap" is shifting to software-based algorithms that even quantum computers cannot solve.

Security is rarely just a technical problem. A "quantum leap" is also required in how we manage data lifecycle: Do We Need Quantum Leaps in Security?

: 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) : Moving away from "perimeter" security to a

This is a hardware-based leap that uses the laws of physics—specifically quantum mechanics—to secure data.

: Uses error-correcting codes to create security. A "quantum leap" is also required in how

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)
