A Hidden Risk in Quantum-Safe Designs As the cryptographic world prepares for the post-quantum era, much of the focus has shifted toward algorithms believed to be resistant to quantum attacks. Among the most prominent of these are noise-based constructions, particularly lattice-based cryptography. These systems promise security not from secrecy of data, but from mathematical…

A Critical Look at Noise-Based Security in Quantum-Safe Cryptography Introduction: Security Built on Uncertainty Quantum-safe cryptography was designed to survive a future where quantum computers break today’s public-key systems. To achieve this, many post-quantum schemes rely not on number-theoretic hardness, but on structured randomness, often referred to as noise.At first glance, this sounds elegant:…
