Abstract: This paper analyzes the shortcoming of current anti-forge technique. Combining the information security with RFID technique theory, it presents the anti-forge RFID reader which conforms to international standard. The discussion about anti-forge mechanism and the encrypt algorithm are emphasized. The realization of anti-forge reader prototype system based on FPGA is introduced. The anti-forge algorithm and authentication of reader algorithm is realized. The IP core of anti-forge algorithm is realized in the hardware system. The effective distinguish and the protection for commodity is provided.

Key words: anti-forge reader, Radio Frequency IDentification(RFID), IP core, FPGA
