Research And Implementation Of Certificates Security And Traceability System Basedon RFID Technology

With the rapid development of RFID radio frequency technology,a new generation of information technology represented of RFID provided new techniques for intelligent security.As "Source" license security application the RFID smart labels were integrated into the system to provide "comprehensive information" service for licenses security.This topic is based on the physical security and digital security,the RFID smart label was embedded into license as a license of "DNA",the establishment of security certificates traceability system based on RFID technology to achieve non-contact identification,flexible,multi-function security security validation while business license accreditation,issuance,supervision and management process provides traceability of electronic channels.The system also achieved the combination of traditional,digital,and intelligent security.The application will fill the domestic blank in this field,and the topic has a certain significance and application value.Faced with threats that may arise license,the paper analyzes the principle of RFID technology,chip storage structure and system security technology,arounding two core areas of security and traceability.With concern of business requirements,constraints,function,this paper carried out a framework for the detailed design of the outline design and functionality RFID traceability system of security certificates to determine the design objectives and design principles of the system.The system has three-tier security system for overall architecture and functional framework for various sub functions of the system were clearly divided and modular design.Finally the paper completed the design goals of building electronic traceability authentication security system to achieve the verification of license information collection,purpose retrospective inquiry and information management.Based on the requirements analysis and system design,the license security traceability system of RFID achieved the ultimate four aspects of security functions from registration control,information management,labeling and traceability verification generate.System is mainly based on the following.NET Framework Class Library WPF application developers to design a CS architecture system with interface layer 3,and through Visual Studio 2010 development tools RFID reader program for secondary development,database development is realized using SQL server2008.The system is based on the material level,to achieve a three-level encryption to encrypt and markings secondary information tag information and database information than to ensure the stability and security.I believe that will be available in the field of public safety certain technical support and get a certain application.
