【摘要】：随着信息技术,特别是保全技术、通讯技术、网络技术的持续进步,自动化办公的认可与使用程度越来越高,已经在政府和不同类型的企业之间得到了广泛的普及。自动的办公系统有效提高了办公效率,加速了讯息的传达,更是很大程度上节省了纸质办公资源。印章以及签字自诞生之日起,便在传统的办公和事务处理中扮演着十分重要的角色。近几年发展起来的电子签名更是得到了不断的普及和发展,其技术日趋成熟,法律上也得到了认可。在这个大背景下,将电子签名应用于OA办公系统,深入到企业的决策和审批流程中具有着重大意义。本文首先在整体上论述了课题的来源、背景,同时介绍了OA办公系统在国内外的发展状况,介绍了电子签名的立法情况,论述了电子签名在法律上的效力。然后从密码学的基础介绍为切入点,对比了几种常见的解密和加密方案,以及PKI与数字签名是通过什么样的方式得以实现的。其次,对保证该系统安全性、便利性、可扩展性所采用的虚拟专用网(VPN)技术和三层C/S模式也进行了介绍。再次,介绍了本系统所采用的USBKEY认证方式。本文紧接着对系统的需求进行了分析。在总括上的设计和实现的方式进行了研究,系统功能模块也加以介绍、分析,最后给出了整个系统的业务办理流程。
[Abstract]:With the continuous progress of information technology, especially security technology, communication technology and network technology, the degree of recognition and use of automation office is becoming more and more high, which has been widely used between the government and different types of enterprises. Automatic office system effectively improves office efficiency, speeds up the transmission of information, and saves paper office resources to a great extent. Since its birth, seals and signatures have played an important role in traditional office and business processes. In recent years, the electronic signature has been popularized and developed continuously, its technology is maturing day by day, and the law has also been recognized. Under this background, it is of great significance to apply electronic signature to OA office system. Firstly, this paper discusses the origin and background of the subject, introduces the development of OA office system at home and abroad, introduces the legislation of electronic signature, and discusses the legal effect of electronic signature. Then, from the basis of cryptography, this paper compares several common decryption and encryption schemes, and how to implement PKI and digital signature. Secondly, the virtual private network (VPN) technology and the three-layer C / S mode are introduced to ensure the security, convenience and expansibility of the system. Thirdly, the USBKEY authentication method used in this system is introduced. Then this paper analyzes the requirements of the system. The design and implementation of the system are studied, and the function module of the system is introduced and analyzed. Finally, the business process of the whole system is given.
