Spinoff technology from quantum computing research has produced what is hoped to be a game-changer in cryptographic key security. Quantum Base, a spinoff company from Lancaster University’s Quantum Technology Centre, believe they have solved the problem of true random number generation; made it scalable, and reduced its size such that it can fit in any tech device. Results in many of the random number generators in use for cryptographic keys are predictable be it due to quirks in the algorithm used to vulnerabilities in the device producing the pseudo random number. Studies with quantum tunneling in semiconductors, specifically, RTDs – resonant tunneling diodes – has enabled true quantum random number generation at room temperature. Cryptographic keys utilizing true random numbers may now be produced, say, in your smartphone to secure your data. The applications are many.
