Development of a Device for Obtaining High Entropy from Photon Noise in Cryptographic Applications

The work is concerned with the development of a prototype of a quantum random-number generator that overcomes the fundamental limitations of traditional methods. Unlike pseudo-random generators, which rely on computational complexity, and classical hardware generators, which are susceptible to external influences, the proposed device is based on the ontological nature of the randomness of the microworld. The source of entropy is fractional noise that arises from the discrete nature of the passage of charges inside the photodetector. This approach guarantees unpredictability, which is the basis for the formation of stable cryptographic keys and digital signatures. The presented device is a comprehensive hardware-software solution. This development offers an efficient and reliable source of entropy for integration into modern security systems, ensuring resistance to attacks, which exploit the weakness of random-number generators.
