摘要
针对视频流数据的实际应用要求,提出了一种新的利用混沌对视频图像数据在频域进行加、解密的视频图像加密算法———EVSBC,并将其实现且集成到最新的MPEG-4编/解码器中.该算法充分利用了视频图像数据的特性,在保证数据安全性的基础上,完全可以满足视频应用中的实时性要求.
Ainfing at the characteristic of video stream and the corresponding requirements in real world applications, a novel video stream encryption algorithm is proposed based on chaotic system-EVSBC. This algorithm encrypts and decrypts the digital video stream in frequency domain. In addition, we integrate this algorithm is integrattd into the latest MPEG- 4 CODEC. The proposed algorithm makes full use of the features of video. And it can completely satisfy the requirement of video-based applications, while the security can be guaranteed actually.
