The power of graphics processing unit(GPU) has been increasing rapidly more than that of CPU. It is not surprising that many software libraries were developed which enable us to use the power of GPU for general computations especially in parallel data processing. In this paper, we propose implementations of the standard block cipher ARIA of Korea using OpenGL and CUDA libraries on GPU. Since ARIA was announced only 4 years ago, there is no hardware solution yet providing high-speed encryption with ARIA. We make use of GPU as a parallel processors with several grid structures and optimize the encryption speed and the occupancy of shared-memory. As a result, when ARIA is running on GeForce 8800GTS using CUDA library, the speed of the encryption reaches up to 4.8 Gbps which is the fastest implementation of ARIA known to public.
