Design And Realization Of The Printing Security Control System

With the development of office automation,network printing are used frequency.The network printing could significantly improve the efficiency of office.People benefit from the network printing,we may have some potential safety hazard.At present,the research on network printing security problem at home or abroad are almost at the blank stage.This paper deeply analysis the safety problems existing in the current network printing and its vulnerable to all kinds of foreign attack.One network printing security system is designed.The system could effectively avoid the existing hidden trouble in security network printing.This security system not only has theoretical research value,but also has important practical value,especially for sensitive sectors such as military,security problem appears additional ly and importantly.Therefore,designing one network printing security system for the continuous development of China's space industry plays a decisive role.Combing with the current actual environment in the field of aeronautics and astronautics,this paper analysis the topic background and the existing safe hidden troubles of network printing.This paper proposes a solution to the existing network printing security hidden danger,and designs a network printing security system structure.The system establish the kernel layer and user layer communication mechanism primarily to accomplish the user identity authentication and dynamic key transmission.The system is used to prevent unauthorized users from using the system and is used to guarantee the security of printing source.In the meantime,the network user request packet encryption transmission realize through using the RC4 encryption technology.Then the filter function for user request will work.Finally all the requested information are printed based on the IPtables firewall rules.Thought of system protection is designing full safeguard measures for the source,route and the terminal.The advantages and disadvantages of the protect ion system are comprehensive analyzed and improvement.At the end of this article,test results show that the designing of network printing security system to a certain extent could significantly avoid the network security problems of the printing.On the other hand the it could improve the network performance against the attack of printing.
