Study on object transaction based on networked RFID systems

Radio Frequency IDentification(RFID) is a novel technology of automated identification. The use of RFID, however, raises great concerns due to the serious security issue. In this paper, we at first propose a Secure Transaction Frame(STF) and a flow of object transaction based on networked RFID systems. Then, it is worth mentioning that the authentication technology in Secure Transaction Frame(STF) is able to verify the ownership of electric tags in order to deal with common attacks in the networked RFID system. Meanwhile, this paper presents an encryption scheme to protect the information stored in electric tags from being illegally used. After collecting relevant statistics and analyzing cases based on networked RFID systems, this paper also researches the mass requests for the information stored in the electric tags by the reader and eventually, gives a cache mechanism to solve that problem.
