APPARATUS FOR GENERATING RANDOM NUMBER BASED ON QUANTUM SHOT NOISE AND CONTROL METHOD THEREOF

摘要

The present invention provides a random number generation that can uniformly distribute the spatial light intensity of an optical signal emitted from a light source and input to each pixel of an image sensor in a situation in which an opening / closing structure capable of opening / closing external light to an image sensor is provided. Start the device. That is, the random number growth value of the present invention includes a light detector including at least one light source, at least one light receiving pixel for detecting an optical signal emitted from the light source, and quantum noise of the amount of light detected by the light receiving pixel. A random number generating unit for generating a random number by using, and an opening and closing unit for operating in one of an open mode for exposing the light-receiving pixel to the external light and a blocking mode for blocking the light-receiving pixel from the external light, the light source is When the light source is operating in the cutoff mode, the optical signal is radiated to allow the random number generator to generate random numbers using quantum noise of the amount of light detected by the light-receiving pixel while external light is blocked.
