摘要
提出了在嵌入式平台上实现混沌视频保密通信的新方式,将基于H.264的视频编解码器移植到Cortex-A8 ARM开发板上,利用H.264编码器对已经混沌加密的视频进行压缩,再通过局域网传输到另一块ARM开发板上进行解码和解密。实验结果证明:该系统不但加密效果好,而且也能快速可靠地传输,满足了实时视频加密通信的要求。
This paper presents a new method of implementing chaotic video encryption based on embedded system,which transplants the H.264 codec to Cortex-A8 ARM board.The codec is used to compress encrypted video data,which is transported to and decrypted on another ARM board.Result shows that the system transfers encrypted videos quickly and reliably, and meets the requirement of real-time video encryption.
