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 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。

Departing from basic concepts of cardinal numbers and their numbering orders, the paper differentiated and analyzed some concepts easy to be confused related to binary system, pointing out that the introduced concepts of ordinals played an important role in the development of modern mathematics. As the foundation of SHAO Yong's mathematics, the primordial Yi , in the history of mathematics, exhibits the first specially defined ordinal system, in which the binary numbering method was used at the first time.
本文从自然数及其记数法的基本概念出发,辨析了与二进位制相关的几个容易混淆的概念,指出序数概念的引入在近代数学发展中有重要意义,作为邵雍数学学派的数学基础,先天易是数学史上第一个专门定义的序数体系,该序数体系在数学史上率先采用了二进位制记数法。
