【摘要】：随着计算机、通信技术的飞跃式发展,互联网得到了大范围的普及,于是,无论在社会经济的任何角落,我们都可以看到:信息化的进程在快速推进;基于网络而发展的新经济形式正在如火如荼的发展。然而,信息化时代下的社会、经济的有序、健康发展都必须依靠良好秩序的保证,政府毫无疑问承担着维护良好秩序的职责,履行着监督、管理和服务信息化社会有序进行的职能。因此,电子政务不仅成为信息化社会发展的“领头羊”,更是加快国家现代化进程的一个崭新机遇。电子政务信息的安全性,不仅是国家和政府的形象,更加关系到国家的安全、社会的稳定,一旦遭遇攻击,将会造成难以预计的严重后果。因此,对电子政务安全性的研究,尤其是PKI技术在电子政务中的应用研究就具有十分重要的理论和现实意义。本文主要工作是利用PKI的网络安全技术,研究并实现了一个基于证书系统的电子政务安全系统。本文在阐述电子政务发展的现实需要的基础上,通过对电子政务及其安全技术的分析确定方案。对PKI技术进行了详细的阐释的同时,选去了RSA作为基础算法为后面的安全体系设计奠定基础。根据实际工作需求设计CA安全系统。在分析电子政务所面临的安全威胁和隐患的基础上,着重对电子政务安全需求进行分析,并制定电子政务安全目标,对系统安全性进行详细研究后,规划电子政务系统设计。对阐释系统功能、数据库设计等系统设计所需的设计出成可行性的系统,实现各个层面的设计功能。最后对本论文所做的研究进行归纳汇总,并对以后的继续研究进行展望。
[Abstract]:With the rapid development of computer and communication technology, the Internet has been popularized in a wide range. Therefore, we can see that the process of information technology is advancing rapidly, no matter in any corner of social economy; The new economic form based on network is developing in full swing. However, in the information age, the society, economic order and healthy development must depend on the guarantee of good order. The government is undoubtedly assuming the responsibility of maintaining good order and carrying out supervision. The management and service information society carries on the function in an orderly manner. Therefore, e-government is not only the leader in the development of information society, but also a new opportunity to speed up the process of national modernization. The security of e-government information is not only the image of the state and government, but also relates to the security of the country and the stability of the society. Once attacked, it will cause unpredictable and serious consequences. Therefore, the research on the security of E-government, especially the application of PKI technology in E-government, has very important theoretical and practical significance. The main work of this paper is to study and implement an e-government security system based on certificate system using PKI network security technology. On the basis of expounding the practical needs of the development of e-government, this paper determines the scheme by analyzing the e-government and its security technology. The PKI technology is explained in detail, and RSA is chosen as the basic algorithm to lay the foundation for the later security architecture design. Design CA security system according to actual work requirements. Based on the analysis of the security threats and hidden dangers faced by e-government, the security requirements of E-government are analyzed, and the security objectives of E-government are formulated. After detailed study on the security of the system, the design of e-government system is planned. To explain the system function, database design and other system design needs to design into a feasible system, to achieve the design of each level of the function. In the end, the research is summarized and the future research is prospected.
