Apparatus and method for extracting noisy entropy source for random number generator

The present invention relates to a random number generating appointed noise source entropy acquisition apparatus and method using a memory access between the GPU (Graphical Processing Unit) core competition. To this end, the noise source entropy pickup device according to the present invention is called a core unit for a call at the same time a plurality of cores to the threshold area; And a plurality of cores, characterized in that it comprises on the basis of the sequence enters a critical section, a generator noise sources of entropy to generate a noise source entropy.
