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 fixed assets are 78 million Yuan. The main equipment for mould is imported from abroad such as: Three coordinate numerical control milling machine imported from Japan, on set; large type the five coordinate milling machine typed dragon imported from Spain, sise (4000 x 2500), one set; three coordinate numerical control processing center size (2000 x 1000) imported from Spain, one set; powerful numerical control milling machine typed dragon imported from Taiwan, size (3200 x 2540), one set; five coordinate milling machine typed with five drift link movement imported from Italy, size (4000 x 2500), one set; Five faces numerical control milling machine HVM502T typed dragon imported from Taiwan, one set; numerical control scanning measuring machine imported from America size (5000 x 2438 x l824), one set. Others sophisticated equipment are made in China, such as numerical control cutting machine, planer typed dragon, pressing machine for research, total 16 set; advanced computer graphical working station, total 40 sets. The automobile cover has become into advantage, which is supplied various auto. Cover mould and cool Press mould to many big factories, such as: Jinan Auto. Manufacturing General Factory, Beijing Light-duty Auto. Manufacture Co., Changhe Auto. Manufacturing Factory, Shandonq Bulldozed General Factory, Jinan Diesel Factory, Qongdao Sifang Locomotive Factory, Dongfeng Auto.

该厂现有固定资产7800万元，用于模具制造的有日本引进的数控三座标铣床一台，西班牙引进的大型五坐标龙门仿形铣床一台（4000*2500），三座标数控加工中心一台（2000*1000），从台湾引进的强力数控龙门铣床一台（32O0*2540），从意大利引进的五轴联动五座标龙门铣床一台（4000*2500），从台湾引进五面体数控龙门铣床HVM502T一台，从美国引进的数控扫描测量机一台（5000*2438*1824）以及国产联高精尖的数控切割机，龙门刨床、研配压床等大型设备 I6 台套，高档计算机图形工作站40多台，在模具制造方面已形成制造汽车覆盖件模具的优势，产品质量达到国内先进水平，多年来为济南汽车制造总厂、北京轻型汽车制造有限公司，昌河汽车制造厂、山东推土机总厂、济南柴油机厂、青岛四方机车厂、东风汽车公司等大型骨干企业的产品更新换代生产制造了各种类型的覆盖件模具及冷冲模具，受到用户的好评，并建立了较稳定的供需关系。

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。
