In this video, Asa Graf explains what hardware random number generators (HRNGs) are, how they work, and why they’re critical to generating real entropy. Unlike software-based methods, HRNGs rely on unpredictable physical processes—such as thermal noise or electrical fluctuations—to create truly random values. These values form the cryptographic foundation of secure systems.

Real Random captures Brownian motion using tamper-evident, optically verifiable hardware to deliver high-entropy randomness at scale. Our modular, rack-mountable units bring physical entropy to data centers, cloud platforms, and edge devices—meeting the demands of post-quantum cryptography (PQC) without compromising performance.
