摘　　要：针对传统的LSB算法易受攻击的特点,通过研究LSB嵌入过程中视频统计特征的变化,结合Diffie-Hellman密码交换协议,提出一种基于密钥交换协议的视频LSB隐藏方法。该方法利用密码交换协议产生的密钥索引来提取视频帧并确定隐藏位置,为隐藏视频增加了密钥验证。实验证明,该方法在具有较大隐藏容量的同时,对视频统计特征改变较小,有效提高了LSB抵抗隐写检测性能。For the shortcoming of vulnerability of traditional LSB, based on studying the changes of video statistical characteristics in LSB embedding process and combining Diffie-Hellman key exchange protocol, We propose a video LSB hiding method which is based on key exchange protocol. The method uses the key index generated by key exchange protocol to extract video frames and determine the hiding position, and adds key verification for hiding the video. Experiments show that while having quite big hiding capacity, this method has small changes in video statistical characteristics and effectively improves the detection performance of anti-steganography of LSB.
