摘　　要：目前基于智能家居的音视频文件在文件传输过程中存在信息泄露等安全问题;此外,智能家居设备普遍受算力和带宽限制。针对此背景,在网络数据包传输理论的基础上,提出一个音视频文件安全传输的方法。该方法将音视频文件的特征部分与数据部分进行切分,形成编码的数据包序列,并对数据包按序列重新排序后传输,保证数据传输的安全性。实验结果表明,该方法传输效率高、算力代价低,能够在受限的环境下实现音视频文件的安全传输。At present,the audio and video files based on smart home have security problems such as information leakage during the file transmission,and the smart home equipments are generally limited by hashrate and bandwidth. Based on this background,a method of the secure transmission of audio and video files is proposed based on the theory of network packet transmission. In this method,the file signature part and the data part of the audio and video files are divided to form the encoded data-packet sequence. The data packets are reordered and transmitted to ensure the security of data transmission. The experimental results show that this method has high transmission efficiency and low hashrate cost,and can realize the secure transmission of audio and video files in a restricted environment.
