    The Power of Hashing in One-Way Security and Irreversible Storage

    In modern digital systems, hashing is one of the most fundamental building blocks of security. It is not encryption, it is not obfuscation, and it is not reversible. Hashing exists for a single purpose: to represent data in a way that cannot be transformed back into its original form. This one way property is…

    When Encryption Depends on Errors, Not Data

    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:…
