Digital Certificate Technology To Achieve Public Security Network-based File Publishing And Tracking System

In recent years, IT technology is developing very fast, especially promotion and practice of computer information networks system connected by cable nets. This enables people have more opportunities to archive, exchange and process information and our life have been changed by it. At the same time, new challenge and opportunities are brought to public security informatization.In the practice of public security work, business layout and procedures are complicated and every part is connected as a net. Therefore, a powerful Info file distribution system will be basic conditions of public security informatization. This automatic office system is based on computer nets and use severs as data centre, making use of the advantage of computer networks, which could share Info with all users in the automatic office system. The purpose of building files distribution and tracing back is to fully make use of advanced IT technology to promoting police managements. This is based on police networks and police practical working platforms.In this system, CA is used as ID verification for accessing office system on the server through police networks. Every user would be given relevant operation authority to access the data. Distribution and accessing data would by means of module management, and the files distributed by users could be traced by users and administrators to know the file statures for accuracy, reliable and security.In order to achieve this, PKI/CA and KMI system enables police officer's Info binding to CA, which could manage Info of police officers and give relevant operation authority of browsing, distribution, approval and tracing accordingly. Info file distribution system provides service interfaces for every department. By means of module management of data, this system could be more flexible and economy and keep consistency of data.This system could reduce the risk of processing public security Info comparing the traditional way. The security problems, such as ID verification, Info transition and access authority would be solved. For different user, ID verification system on the sever could give user relevant operation authority to browse, add, amend and delete data accordingly. "user name +password" way of accessing data would be changed to the CA access, which would have higher level of security to make sure the national secret would not be released through networks. Base on this reason, the author would choose the study of CA technology to enable files distribution and tracing system on police networks as the assertion research. The system should achieve the goals of security file management,reliable transmission and restore of police confidentials.
