Multiple Chaotic Real-time Image Encryption System Based on DSP+FPGA

针对视频图像在数字通信中存在着安全和隐私问题,提出了基于DSP+FPGA技术来实现实时视频图像加密的系统设计方案,并详细介绍了多混沌加密算法在DSP和FPGA上的实现。实验结果表明多混沌实时视频图像加密增强了视频图像传输的安全性,同时证明了本系统对实时视频图像能快速地进行加密。

Aiming at the security and privacy problems of videos/images in digital communications, a system design scheme for realize real-time videos/images encryption is proposed based on DSP＋FPGA, and then the realization of multi-chaotic encryption algorithm based on the DSP＋FPGA is introduced in detail. The experimental results show that the encryption algorithm can enhance the security of the videos/images transmission, and it is proved that the system can run with rather fast encryption speed for the real-time videos/images.
