Implementation of Advanced Encryption Standard for encryption and decryption of images and text on a GPU

Abstract

In this paper, we propose a system for the complete implementation of the advanced encryption standard (AES) for encryption and decryption of images and text on a graphics processing unit. The GPU acts as a valuable co-processor that relieves the load off the CPU. In the decryption stage, we use a novel technique to display the decrypted images and text on the screen without bringing it onto CPU memory. We also present a system for encryption and decryption of hybrid map tiles generated from GIS data sets.
