Study Of Network Printing Security Architecture And Design Of System

Network printers have been increasingly used by modern enterprise, people obtain great convenience through network printing, but also faced with more severe security problems. The paper focuses on the domain of network printer security which is still a blank field. In-depth study of network printing security architecture, the paper designs a network printing security system to solve the unsafe problems of the existing network printer.Firstly, the security vulnerabilities of network printers are analyzed. In view of these vulnerabilities, a strategy to solve the network printer security problems is proposed and a network printing security architecture is designed. The system uses authentication to ensure the source security, uses encryption technology to ensure data transmission security and uses embedded firewall at the front of the printer to enhance the anti-attack performance of the network printer. Secondly, the client platform uses the kernel and user level communication mechanism to enable user authentication and dynamic key transmission, RC4 encryption technology is designed to realize the encrypt transfer, embedded firewall platform uses the kernel packet filter and iptables rules technology to set the firewall rules. The entire network printing security system is completed. At last, the improvement for the system shortcomings is introduced.The experimental results indicated that the embedded platform has enhanced the network printing transmission security and improved the network printer's anti-attack capability effectively.
