Speeding up an Image Encryption usingBit-level Permutation Using GPGPU

By developing internet and information technology, multi-media data such as video, image and sounds are widely transferred to internet and mobile communication. Therefore, security and encryption of images have great importance in information technology. In recent years, many methods have been presented for image encryption. In recent decades, by emerging GPGPU processing, quantitative parallelism has been presented for this algorithm. Increasing execution speed of image encryption algorithm is one of the important aspects of encryption. In diffusion method considered in pixel-levels, encryption is applied for gray values and image histogram distribution. The purpose of this research is to present a parallel method for image encryption based on image encryption design along with an efficient bit-level permutation by considering diffusion method in pixel-level and by using CUDA platform. In this way, system performance increases, and a solution can be developed for this problem.
