Abstract

The invention provides a method and a device for optics based quantum random number generation. A method and device for generating random numbers based on an optical process of quantum nature. According to one exemplary aspect, the method includes randomly emitting photons from a light source and absorbing the emitted photons by a photon sensor having a plurality of pixels. Furthermore, respective minimum entropy levels can be calculated for each of the pixels of the photon sensor and a randomness extractor can be associated with each of pixels based on the calculated minimum entropy level of that pixel. After this calibration, the method and device generates a number of high-entropy bits used for generating a random number.

Description

technical field [0001] The invention relates to a device for generating quantum random numbers based on an optical process of quantum properties and a corresponding method, wherein the device includes a light source for randomly emitting photons, and both the device and the method can obtain high-quality random numbers. Background technique [0002] In general, the context of the present invention is the generation of random numbers. In fact, generating high-quality random numbers is necessary for the security of many applications such as cryptographic protocols (classical and quantum). For example, conventional asymmetric key agreements, such as the well-known DSA-algorithm, RSA-algorithm and Diffie-Hellman algorithm, use random numbers for primality testing to generate their keys. Another example is the unconditionally secure one-time pad protocol, which requires a string of completely random numbers of length equal to the length of the data to be encrypted. The main lim...
