A group of researchers with KAUST (King Abdullah University of Science and Technology) have announced a new, groundbreaking manufacturing technique for what is known as "memristors" - circuits that are one of the four fundamental electrical components, alongside resistors, capacitors, and inductors. The new technique has been shown to enable the creation of one of cryptography's essential components, a True Random Number Generator (TRNG).
True Random Number Generators are essential parts of cryptography, and perhaps unintuitively (after all, how hard is it to produce random numbers?), it's also one of the most prone to failure. That's because it's easy for a random distribution (that is, when all possible events have an equal chance of happening) to become a non-random distribution.
