摘要
电子信息技术的发展,使得电子文件越来越多地形成于日常办公和档案管理中。但电子文件具有易改动性和易复制性,在传播过程中的完整性保护问题越来越凸显。文中提出了一种加密环境中保证文件备份完整性的实现方案,并以此实现方案为主线,介绍了一个基于多线程技术的文件备份完整性保证系统的设计与实现。系统具有对主机中指定类型的活动文件自动、强制备份的能力,同时具有较好的容错能力。并对实现过程中的一些难点技术问题进行了详细的讨论。
With the development of electronic information technology, electronic documents are widety applied in daily office and file management. For its easy change and copy the integrity protection of the electronic documents becomes more and more prominent in the communication process. Though study of the file system, and for assurance of file backup and file integrity, an encryption-based real time file integrity backup solution is proposed, and the design and implementation of the file backup integrity assurance management system is given, and some characteristics and related key techniques in this system also described in this paper.
