Abstract

Parallel computing is able to guarantee a much faster performance when compared to the sequential versions of the algorithms, which has been much explored in research in several areas. In cryptography, where more and more data needs to be encrypted securely and efficiently, graphics cards appear as a cost-effective alternative for running these algorithms in parallel. This study examines the performance of Blowfish and RC6, two efficient and popular cryptographic algorithms, in their sequential, C ++ and parallel versions, using the GPU through the CUDA programming model and compares the performance achieved.
