【摘要】：近年來,我國的政務(wù)網(wǎng)站建站水平得到了巨大的提高,分別經(jīng)歷了網(wǎng)站風(fēng)格統(tǒng)一、信息共享、聯(lián)合全文檢索、統(tǒng)一內(nèi)容管理、動(dòng)態(tài)內(nèi)容管理、子站獨(dú)立存儲(chǔ)等技術(shù)革新,但仍然存在以下問題:資源浪費(fèi)嚴(yán)重、數(shù)據(jù)共享度低、區(qū)域性發(fā)展不平衡;部門間缺乏協(xié)調(diào)合作,各自為政,普遍缺少統(tǒng)一規(guī)劃、統(tǒng)一技術(shù)和統(tǒng)一建設(shè);信息資源的公開、共享程度較低;重硬件輕軟件;形象工程,華而不實(shí),與政府的本職工作及核心業(yè)務(wù)有所背離;對(duì)行政許可,發(fā)布信息及公眾參與問題涉及較少,僅提供了信息發(fā)布;軟件系統(tǒng)缺乏嚴(yán)格的標(biāo)準(zhǔn)規(guī)范,電子政務(wù)標(biāo)準(zhǔn)也有待提高;并且需要增強(qiáng)同級(jí)單位間的水平整合及上下級(jí)單位之間的垂直整合;另外,安全管理問題、內(nèi)部審計(jì)及維護(hù)問題的重視度也有待進(jìn)一步提高。本文針對(duì)存在的諸多問題,設(shè)計(jì)了一種基于云計(jì)算模式的電子政務(wù)網(wǎng)站群的解決方案,該方案針對(duì)網(wǎng)站群內(nèi)主站和各個(gè)子站具有相近或者相似功能和業(yè)務(wù)流程的特點(diǎn),基于這樣的一個(gè)基本流程:首先是電子政務(wù)功能的模塊化,即根據(jù)各個(gè)電子政務(wù)網(wǎng)站本身的功能或者性能特點(diǎn),按照云計(jì)算的特點(diǎn)進(jìn)行功能分解,解析出相同或者相近的功能模塊,形成相應(yīng)的模塊類別;然后在適合的云計(jì)算平臺(tái)上進(jìn)行建設(shè)和部署該業(yè)務(wù)的功能模塊;最后進(jìn)行模塊間的關(guān)聯(lián)和對(duì)接,并形成完整的政務(wù)業(yè)務(wù)流程。同時(shí)對(duì)相關(guān)技術(shù)進(jìn)行了深入探討和研究。本文在以下幾個(gè)方面實(shí)現(xiàn)了較大創(chuàng)新:1.在分析云計(jì)算、電子政務(wù)、電子政務(wù)群等概念及其研究的基礎(chǔ)上,構(gòu)建了基于云模式的電子政務(wù)管理網(wǎng)站群�；谠颇Ｊ降碾娮诱⻊�(wù)管理網(wǎng)站群與傳統(tǒng)的網(wǎng)站群管理系統(tǒng)有明顯的區(qū)別,該網(wǎng)站群基于B/S技術(shù)構(gòu)建,可以實(shí)現(xiàn)跨平臺(tái)平滑遷移,并且能夠提供靈活的網(wǎng)站創(chuàng)建方式和多樣的發(fā)布形式。2.設(shè)計(jì)實(shí)現(xiàn)了一種基于Elgamal密碼的電子政務(wù)網(wǎng)站群體簽名機(jī)制,并將其應(yīng)用到云計(jì)算模式下的電子政務(wù)管理網(wǎng)站群方案中。該方式同傳統(tǒng)的安全體制相比,可以突破時(shí)空的限制,實(shí)現(xiàn)數(shù)據(jù)的實(shí)時(shí)感知和實(shí)時(shí)傳輸,提高平臺(tái)對(duì)突發(fā)事件的應(yīng)急處理能力;同時(shí)該方式可以提高服務(wù)器集群的運(yùn)算能力和數(shù)據(jù)處理效率,提高感知數(shù)據(jù)信息的安全性;該方法還能整合各個(gè)孤立的安全信息,最終能夠指揮調(diào)度高效統(tǒng)一的安全事件。3.對(duì)安全審計(jì)相關(guān)技術(shù)進(jìn)行了研究,并設(shè)計(jì)、實(shí)現(xiàn)了一個(gè)基于多Agent和數(shù)據(jù)挖掘的電子政務(wù)管理網(wǎng)站群安全審計(jì)系統(tǒng),同傳統(tǒng)的安全審計(jì)系統(tǒng)相比,多Agent可以通過協(xié)作提高數(shù)據(jù)處理能力,數(shù)據(jù)挖掘技術(shù)可以更加準(zhǔn)確和及時(shí)的發(fā)現(xiàn)網(wǎng)站群中存在的異常行為,提高系統(tǒng)安全性。4.在研究電子政務(wù)網(wǎng)站評(píng)價(jià)體系的基礎(chǔ)上,提出了一種基于模糊集的電子政務(wù)網(wǎng)站評(píng)價(jià)體系,并針對(duì)本文設(shè)計(jì)的管理平臺(tái)進(jìn)行了評(píng)估。本文提出的評(píng)價(jià)體系和評(píng)價(jià)方案能夠更加客觀和準(zhǔn)確的評(píng)價(jià)電子政務(wù)網(wǎng)站群,可以應(yīng)用于各類網(wǎng)站效能評(píng)價(jià)。5.針對(duì)山東省電子政務(wù)建設(shè)中存在的問題,通過調(diào)研和數(shù)據(jù)分析,提出了相應(yīng)的意見和建議。本文提出的意見和建議來源于調(diào)研和真實(shí)數(shù)據(jù),通過科學(xué)的分析方式進(jìn)行分析,所以所提出的意見和建議具有較強(qiáng)的參考價(jià)值。
[Abstract]:In recent years, the government website in China has been a huge increase, respectively through the website unified style, information sharing, joint full-text retrieval, unified content management, dynamic content management, sub station independent storage technology innovation, but there are still the following problems: the serious waste of resources, low degree of data sharing, regional unbalanced development; lack of coordination between departments, lack of coordination, lack of unified planning, unified technology and unified construction; public information resources, sharing degree is low; light weight hardware and software; image project, China is not real, and a departure from the job and the core business of the government; on the administrative license, and publish information public participation in issues related to small, only provides information dissemination; the lack of strict standards of software system, e-government standard needs to be improved; and the need to enhance the level of integration with the upper and lower level units The vertical integration level between units; in addition, safety management, internal audit and maintenance of attention also needs to be further improved. Aiming at the existing problems, designed an e-government website based on the cloud computing model group solutions, this scheme has the characteristics of similar needle or similar functions and business processes of the website group of master station and sub station, a basic process based on this: the first is the modular functions of e-government, the e-government website itself according to each function or performance characteristics, functions in accordance with the characteristics of cloud computing, analysis function module of the same or similar form, then the corresponding module category; the calculation function module on the platform construction and deployment of the business for the last cloud; correlation and docking between modules, and form a complete e-government business process. At the same time, the related technology in-depth study and research. This paper realized the great innovation in the following aspects: 1. in the analysis of cloud computing, e-government, basic concept and research of e-government group, was constructed based on the cloud model of e-government website group management. Cloud model of e-government websites and traditional management the website group management system based on a clear distinction, the website group build based on B/S technology, can achieve cross platform migration smoothly, and can provide a flexible and diverse way of creating website release form.2. design and implementation of a Elgamal password mechanism based on e-government website group signature, and its application to e-government cloud management Web Computing model group scheme. Compared with the traditional security system, can break through time and space constraints, to achieve real-time sensing data and real-time transmission, improve Emergency handling ability of the platform; at the same time the method can improve the operation ability and the efficiency of data processing server cluster, improve the data security of information perception; the method can integrate various isolated security information, eventually.3. security events dispatching unified and efficient related to the security auditing technology research and design. Based on the e-government management website Agent and data mining group security audit system, compared with the traditional security audit system, Agent can improve the data processing capacity through collaboration, data mining technology can be more accurate and timely find abnormal behavior exists in the website group, foundation to improve the system security in.4. the research of E-government Website Evaluation System, put forward a kind of e-government evaluation system based on fuzzy sets, and for the design of the The management platform is evaluated. The evaluation system and the evaluation method proposed in this paper can be more objective and accurate evaluation of e-government website group, can be applied to all kinds of website performance evaluation of.5. in Shandong Province in the construction of e-government, through research and data analysis, put forward the corresponding opinions and suggestions. This paper puts forward opinions and recommendations from the investigation and real data, through the analysis of the way of science, so the views and suggestions with strong reference value.
