Physical Random Number Generator Service

Physical random numbers have great application value in the fields of cryptography, communication and national security. With the appearance of wideband photonic entropy sources (e.g. chaotic laser and amplified spontaneous noise) in recent years, lots of schemes for high- speed random number generation are proposed. Our group proposed the following methods of generating random numbers.

Fully photonics-based physical random bit generator

To ensure high-quality of the supplied random numbers (true randomness) and high speed of serving, we have used fast non-deterministic, stand-alone hardware number generator relying on Chaotic circuit . Using topological dynamics techniques to determine the chaos of a specific system.

Physical random number generator

Based on the understanding of the existing random number generator, the existing three kinds of physical random number generation scheme: noise source amplification, oscillator sampling, chaotic system
