摘 要:由于现有的传输方法数字媒体视频图像的关联性大,不动点数量小于6,为此研究基于无线通信的数字媒体视频安全传输方法。先通过优化无线信道衰减参数来提高无线通信系统的性能,获得更大的信道容量。然后视频数据通过上行链路,选择最优频段高效的数据传输。运用节点同步算法通过协同组合性协议来减少在节点不存在时的节点间通信量,确保数据在各个节点之间保持一致性和安全性。最后在传输前对视频信息进行压缩处理,通过加密确保传输过程中信息的安全性。实验结果表明,数字媒体视频图像的关联性减少,使得其对于攻击的抵御能力更强;灰度值在图像中呈现出较为均匀的分布状态,从而保障了信息的安全性。Due to the high correlation between existing transmission methods for digital media video images and the number of fixed points being less than 6,a secure transmission method for digital media video based on wireless communication is studied.Firstly,optimize the wireless channel attenuation parameters to improve the performance of the wireless communication system and obtain a larger channel capacity.Then the video data is transmitted through the uplink,selecting the optimal frequency band for efficient data transmission.Using node synchronization algorithms to reduce inter node communication in the absence of nodes through collaborative composite protocols,ensuring consistency and security of data between nodes.Finally,before transmission,the video information is compressed and encrypted to ensure the security of the information during transmission.The experimental results show that the correlation between digital media video images decreases,making them more resistant to attacks;The grayscale values present a relatively uniform distribution in the image,thereby ensuring the security of information.
