Abstract
The present invention relates to an apparatus and method for acquiring noise source entropy for a random number generator, which use contention for access to memory between Graphical Processing Unit (GPU) cores. For this, an apparatus for acquiring noise source entropy for a random number generator includes a core calling unit for simultaneously calling a plurality of cores to a critical area, and a noise source entropy generation unit for generating noise source entropy based on a sequence of entry of the plurality of cores into the critical area.
Claims16
