Abstract: This paper is a continuation of“TheAnti-interception Characteristics of Code-Division Radio Frequency Identification (CD-RFID)”.The requirements of anti-attack characteristics of UHF RFID are introduced, and the malicious attacks thatUHFRFID may be attacked are emphasized.The currentUHFRFID system has no solution to this problem. However, the inherent security elements of code division radio frequency identification system constitute anti-attack capability against various attacks using detecting receiving information and utilizing recognition information.

Key words: CD-RFID, Security of the internet of things, Security elements
