The goal of this paper is to study the possibility of using alternative computing solution in cryptography, the use of a graphic processing unit in non graphical calculations. We tried to use the graphic processing unit as a cryptographic coprocessor in order to obtain more computing power and better runtime for AES. In this paper we present an implementation of AES on NVIDIA GPU using CUDA. The results of our tests show that the CUDA implementation can offer speedups of almost 40 times in comparison to the CPU. The tests are conducted in two directions: running the tests on small amount of data that is located in memory and a big amount of data that are stored in files on hard drives and as news, the access time for the information on the hard disk is added to the encrypting time.
