QRNG Claims ‘Unbreakable’ Online Security

Creation of the world’s first practical quantum random-number generator (QRNG) could potentially render cyberattacks impossible, according to its developers at Lancaster University and Quantum Base Ltd., a company spun off from the university in 2013.

Random-number generation underpins the privacy and security of all electronic communications, as well as gaming, cryptocurrencies, smart appliances and vehicles, and much more in the digital world. Conventional “pseudo” RNGs don’t produce numbers that are as random as most consumers believe, leading to potential predictability, and existing quantum solutions are hindered by their size, speed, and pricetag.

Quantum Base, on the other hand, claims its product’s low power requirements and simple, highly scalable structure make it capable of revolutionizing online security. The nanoscale quantum device—only 1,000th the width of a human hair—can be embedded into any semiconductor chip—“with little or no incremental cost once volume production is achieved,” according to a release—and produces “pure random numbers.”

The company said that by overcoming weaknesses in current encryption solutions, its QRNG will "allow blockchain to be implemented with unbreakable quantum security, and will be vital in sensitive areas such as banking finance, defense, and social media."
