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.

Abstract: An apparatus and method that generate a trigger signal required for side channel analysis by analyzing the data of a smart card cryptographic module in real time. In the trigger signal generation method, a data input/output signal of a cryptographic module is monitored in real time. A preset section in the data input/output signal is analyzed. A reference signal is generated using the data input/output signal and a signal obtained from results of analysis of the preset section, and a trigger signal is generated using the reference signal.
