Abstract

In this paper, we are interested in image protection within limited calculation resources environment like a laptop with large amount images as input. Full traditional encryption of the data stream is not fast enough and takes too much CPU calculation resource in such an environment. We derive a new solution combined selective encryption with current GPGPU (General Purpose Graphic Process Unit) acceleration. After presenting related works, we introduce a new architecture and implementation of a selective encryption method by utilizing all calculation resources of a laptop including CPU and GPGPU. Then performance of our design is given and compared with traditional full encryption method.
