Abstract
The present invention presents a device and method for managing the performance of a quantum noise-based random number generator, the device ensuring the performance stability of a random number generator on the basis of an output value for each pixel, which is outputted in correspondence to an optical strength value of an optical signal emitted from a light source and inputted into each pixel, so as to be capable of outputting, within a certain range regardless of devices, a value of an entropic signal outputted from an image sensor, thereby enabling sufficient randomness to be continuously maintained while minimizing deviation between pixels.
