【摘要】 伴随着计算机和网络应用的不断普及,运用这一技术来处理政府的日常事务,提高政府工作效率,改善政府行政形象,已经成为各国政府的共识。于是,电子政务这一新生事物应运而生。在过去的几年中,电子政务系统迅速地在我国得到广泛地应用。经过几年不懈努力,部分经济发达地区的电子政务系统已经迅速的普及到公安、工商、税务、物价、海关等多个部门,也给人们提供了另外一种与政府交往的途径,收到了良好的效果。但是,电子政务在给人们带来方便的同时,其安全性也越来越广泛地受到人们关注,利用窃取权限、非法侵入等手段对电子政务系统进行入侵、破坏等活动已经成为黒客的惯用手段。因此,安全问题已成为电子政务发展的一个瓶颈。如何充分保障电子政务系统运行的高效性、安全性,已经成为各国政府极为关注的问题,也是各个电子政务系统建设中要潜心解决的问题。本文在基于南京市电子政务系统的背景下,研究并实现了提高电子政务系统效率的几个改进方法和安全性的体系结构。利用改进的AES算法对明文进行加解密,再利用改进的RSA算法对AES的密钥进行加解密,网上传输的数据通过SSL通道进行传输,最后用PKI/CA技术进行身份认证和访问控制。综合上面的几种技术给出一个高效、安全的数据传输体系结构,并用跨平台的J2EE技术实现了本系统。本系统在理论和实践两方面都证明是高效、安全的。更多还原

【Abstract】 With computer and network continuously permeate, to use the technique to handling daily work of government, to enhance work efficiency, improve administration’s face of government, have already become common ground in the government all over the world, hence, electronics government, the new-born business emerge with the tide of the time. In the past of years, electronics government is quickly to get broadly applied in all countries. For the few years of effort, our country’s part the electronics government system of the economic and prosperous region the system and quickly make widely available many of public security official, industry and business, tax administration, commodity price…etc. This provides to people another path to affiliate with the government, and received very good results. But, at the same time, electronics government bring convenience to people, its safely also concern by people more and more, by using of pilferage legal power, illegal broken etc to invade the electronics government system have already become the hacks’main methods. The problem of security has become a key-point in the development of electronics government.How do sufficiency ensure electronics government run high-efficiency and security? This has become a importance problem of every countries, also turn into each electronics government system’s development going deep into solve technique. In this paper, based on Nanjing electronics government system, research and implement a few of methods of improving electronics government’s efficiency and security architecture. We make use of improved AES algorithms encrypt and decrypt the clear text, improved RSA algorithm encrypt and decrypt AES-key with CA’s public key and private key. The data to be transmitted on the network are passed the SSL channels. In the end, we carry on identity authentication and visit to control with PKI/CA technology. Combine several kinds of technology above and provide a high-performance, safe data transmission system structure, and use surpass J2EE technology implement this system.This system has proved in two respects of theory and practice it is high-efficient, security in this paper.更多还原
