摘要
针对目前实时视频泄露问题日趋严重的现状,提出了一种基于SM4算法和选择性视频加密算法的混合视频加密算法。利用SM4算法的强安全性,对加密技术中的密文反馈模式进行了改进,并和实用性较强的选择性视频加密算法进行混合产生一种新的视频加密算法。在保证视频加密效率的同时,极大程度地提升了视频数据在传输过程中的安全性。实验结果表明,本算法在视频加密传输的实时性和可靠性方面具有更高的时效性和抗攻击能力。
A hybrid video encryption algorithm based on domestic SM4 algorithm and selective video encryption algorithm is proposed to solve the problem of real-time video leakage.By taking advantage of the strong security of domestic SM4 algorithm,the ciphertext feedback mode in encryption technology is modified,and a new video encryption algorithm generated by mixing it with the selective video encryption algorithm with strong practicability.While guaranteeing the video encryption efficiency,the security of video data in the video transmission process is greatly improved.Experimental results indicate that the algorithm has higher timeliness and anti-attack capability in real-time performance and reliability of video encryption transmission.
