Zusammenfassung:The present invention relates to an apparatus and a method for obtaining noise source entropy by using memory access competition between graphical processing unit (GPU) cores. The noise source entropy obtaining apparatus includes: a core calling unit for calling a plurality of cores in a critical region simultaneously; and a noise source entropy generating unit for generating a noise source entropy in the order of entrance into the critical region.
