Why does this matter for security? Randomness is the backbone of cryptographic security, yet most systems still rely on software-based randomness. This video does a great job breaking down why true random number generation matters—and how computers often fall short. If you’re navigating post-quantum readiness or securing edge devices, understanding the difference between PRNG and…
Read MoreIn 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. Watch the video…
Read MoreThis educational video—produced with support from the National Science Foundation—offers a clear, beginner-friendly introduction to random number generation. It explains the difference between true randomness and pseudorandomness, using real-world demos to illustrate why the distinction matters in everything from science to cybersecurity. Watch a video published by Dave Ackley’s YouTube channel about randomness and pseudorandom…
Read MoreThis video dives into the inner workings of random number generators (RNGs), focusing on how microcontrollers create seed values. These seeds are the foundation of randomness in both pseudo and true RNGs. If the seed isn’t truly unpredictable, the entire encryption system may be compromised. Watch a video originally posted by 0033mer YouTube channel showing…
Read MoreRandomness plays a critical role in everything from cryptography to simulations. But not all randomness is created equal. This video dives into the difference between true and pseudorandom number generators, including how the Neumann algorithm works and why “periods” in pseudorandom sequences create predictability that weakens security. Real Random uses tamper-evident hardware to harness Brownian…
Read MoreHow It Works: The Real Random Approach to Post-Quantum Security Random numbers are the invisible force powering encryption, digital authentication, and secure communication across every online system, from e-commerce checkouts to IoT networks. But here’s the catch: nearly all of these numbers aren’t truly random. They’re pseudorandom—generated by mathematical algorithms that, while hard to predict,…
