基于DSP builder的视频图像实时加密实现

Real-time Video Image Encryption based on DSP Builder

文中不仅提出了一种基于DSP builder的视频图像硬件加密的实现思路,而且还提出了一种Arnold加密算法直接对灰度值进行运算的快速加密算法实现。借助于Matlab强大的计算能力以及Simulink丰富的仿真验证平台,利用Altera提供的DSP Blockset工具箱搭建算法实现模型,在仿真验证功能正确后生成FPGA映射文件下载到FPGA成功实现视频图像的硬件加密。

This paper proposes a way to realize video image hardware encryption based on DSP builder,and an Arnold encryption al-gorithm to directly realize fast encryption of gray value. By virtue of Matlab's powerful calculation capability and Simulink's powerful simulation platform,the algorithm model is built up with DSP Blockset toolbox provided by Altera. After simulation function is correctly verified,FPGA mapping file is generated and downloaded to the FPGA,thus successfully realizing hardware encryption of video image.
