Design And Research Of The Anti-counterfeiting System Based On RFID

With the deepening of China’s reform and opening up and the economy continues todevelop, forgery, counterfeiting has become a serious social problem. Establish and improverelevant laws and regulations at the same time, how to improve anti-counterfeiting technology,to make up for lack of the rule of law through advances in technology, perhaps get a shortcutto victory in the fight against counterfeiting.Currently, Using RFID technology in the field of security is a hot topic related industriesboth on our country and abroad. RFID is a radio frequency identification technology, is one ofthe core technologies of Things perception layer. The function of RFID is mainly to identifyitems, collect information, etc. It is cargo tracking, traceability, one of the best means ofsecurity, and it has read easily and quickly, long identity distance, large data memory capacity,high security and other advantages. When RFID tags are numbered chip factory is written,unique in the world and can not be tampered with, and when it is attached to the object thathas peeled off the self-destruct after the security function, can effectively prevent theft.This paper describes the working principle and the RFID system components, then forthe theme of anti-counterfeiting, study RFID tags anti-counterfeiting to means of physicalprotection and encryption methods, and which relates to cryptography and data compressionalgorithms such as RSA, Hash, LZW algorithm analysis and simulation. And later combinedwith existing authentication protocol between the handset less RFID tags, propose a securityauthentication protocol based Hash functions. Finally, write the solution of the actual project-Zhaoqing Duanyan RFID security projects and of complete hardware and software design ofthe system.
