Image Encryption Algorithm Based on the Hardware Platform

The image is an important carrier under the network platform. With the development of the Internet, the image transmission becomes fast and easy. These images always carry a lot of confidential information. In recent years, the image security attracts the attention of scholars at home and abroad. Traditional image encryption is mostly designed based on the software. In recent years, with the development of hardware platforms, DSPs and FPGAs are applied to image encryption for its processing speed, logic computing power and low cost. This paper introduces the technology of image encryption. Meanwhile, this paper mainly describes the image encryption algorithm based on DSP and the image encryption algorithm based on FPGA. Their advantages and disadvantages are also discussed. Finally, we prospect the application prospect of FPGA in the field of image encryption.
