Random number generators (RNGs) are critical to the daily lives of billions of people across the planet. It is a fundamental aspect underpinning online security and privacy, which depend on the quality of random numbers.
Random numbers are important in cryptography, simulations, and gaming. Many applications rely on what is termed ‘pseudo’ random number generators, but information security requires ‘true’ random numbers for ultra sensitive applications such as banking and Fintech, defence, and even social media.
True random number generators are systems whose outputs cannot be determined, even if their internal structure and response history are known. For example, security in Blockchain is derived from public key cryptography but weaknesses in the implementation of these security measures include the failures to derive public and private keys randomly, a lack of secure storage and an inability to prevent cloning of keys.
At Quantum Base, we have invented and developed a true quantum random number generator (QRNG) using quantum tunnelling in a simple semiconductor structure, namely a resonant tunnelling diode (RTD).
