PQC and QRNG: The Foundation of Quantum-Safe Security
in QRNG BasicsNo matter which post-quantum cryptographic algorithm you use, seeding it with weak or predictable randomness undermines its security. High-quality randomness is not optional in a quantum-safe system. It is foundational. What is post-quantum cryptography? Post-quantum cryptography refers to cryptographic algorithms designed to remain secure against attacks from quantum computers. Classical algorithms such as RSA and…

TRNG to QRNG
in QRNG BasicsUpgrading from TRNG to QRNG: What Changes and Why It Matters True random number generators were a significant improvement over pseudorandom algorithms. They draw randomness from physical processes rather than mathematical formulas, producing output that is genuinely unpredictable. For many years they were the standard for high-security randomness generation. Quantum random number generators take a…

QRNG vs PRNG: What Is the Difference?
in QRNG BasicsNot all random numbers are created equally. The method used to generate them has direct implications for security, predictability, and suitability across different applications. This article explains the key differences between quantum random number generators and pseudorandom number generators. What is a PRNG? A pseudorandom number generator is an algorithm that produces a sequence of…

How Does a Quantum Random Number Generator Work?
in QRNG BasicsA quantum random number generator produces random numbers by measuring the outcome of quantum physical processes. To understand why this produces genuine randomness, it helps to understand a key principle of quantum mechanics. The quantum principle behind QRNG In classical physics, if you know the state of a system precisely enough, you can predict its…

What Is a Quantum Random Number Generator?
in QRNG BasicsRandomness is everywhere in digital security. It underpins encryption keys, authentication tokens, secure communications protocols, and many other systems we rely on daily. But not all randomness is equal, and the source of that randomness matters more than most people realise. A quantum random number generator, or QRNG, is a device that produces random numbers…
