Design And Implementation Of Secure E-Government Based On PKI Technology

The government departments are taking on important roles in the economic development and construction. With network application developing increasingly, some important government services have already been taken through Internet. With the development of the E-government, the workings of government departments have been changed. How to improve the government's working efficiency through ensuring information security is a hot question. The technique of PKI can well solve secure problems which E-government faces. It may efficiently solve these questions including the confidentiality, the authenticity, the integrality, the access control, etc. Thus the technique of PKI has been applied to E-government. PKI system is the core of the technique of information security, including a series of hardware, software, policies and persons. After the PKI system is completely implemented, information security is assured to protest sensitive communication. After analyzing and researching current information security technology, we propose a systemic model of information security based on PKI/CA and discuss its function, structure and components, etc. Based on the model, we design and implement a secure E-government information system. The paper has finished the following works: 1. The paper analyzes the main drawbacks of current information security, discusses the main techniques of solving these problems, and proposes a systemic model of information security based on PKI/CA. 2. Based on our systemic model of information security, we design and implement a secure E-government information system. The system is composed of several components, the designs and implementations of which are described in detail. 3. The paper summarizes benefits and advantages of applying PKI/CA technology on E-government. Based on our own research results, we put forward developing trends and main research directions.
