Key management is the core problem of network system security, which deals with the correlative problems from key being generated to ultimately destroyed; it includes system initialization, key generation, key encasement, key distribution, key storage, key renovation, key destruction, etc. Thereinto key distribution and key storage are the two most intractable taches of key management.

密钥管理问题是网络系统安全中首要的核心问题，它是处理密钥自产生到最终销毁的整个过程中的有关问题，包括系统的初始化，密钥的产生、装入、分配、存储、更新、吊销和销毁等内容，而密钥的分配和存储是密钥管理中最为棘手的两个环节。

The telegraph was the first instrument used to send information using wires and electricity. The telegraph sent messages between two places that were connected by telegraph wires. The person at one end would send the information. The second person would receive it.

电报是第一种使用电线传递消息的设备，电报在两个地方之间传送消息，这两个地方必须通过电报线相联系，一个人在一端发送消息，另一个人在另一端接受消息。

The method includes steps: digital watermark technique is adopted to hide information of key data in not key data codes of compressed image; under protection of digital watermark, using protective backup for key data detects whether normal transmitted key data is correct or not so as to detect error code; carrying out cyclic mutual backup by using macro blocks in same positions in front and back macro block set; embedding coded motion vector in form of digital watermark to DCT transformation coefficient, and ensuring that video data are not influenced as best as one can; when error code occurs, if key data backup is correct, then the backup replaces former key data; otherwise, using mean value of key data in adjacent macro blocks within same frame to replace former key data approximately.

本发明中，采用数字水印技术在压缩图像的非关键数据编码中隐藏关键数据信息；通过数字水印保护下的关键数据保护备份来检测正常传输的关键数据是否正确，由此来检测传输误码；用前后宏块组中相同位置的宏块进行循环相互备份；对运动向量进行编码，然后以数字水印的形式嵌入到相对不重要的DCT变换系数中，同时保证视频数据尽量不受影响；在误码发生时，如果关键数据备份正确，则直接替代原关键数据，否则用同一帧内相邻宏块的关键数据的平均值近似替代原关键数据。
