Abstract: The information security issues of Radio Frequency Identification(RFID) system at present urgently needs solution. A new scheme is proposed that the chaotic encryption of information security in RFID system, in order to increase the security of RFID secure mechanism without affecting the operation efficiency. The Logistic mapping whose initial value is variable is used to generate chaotic cipher sequence, and then date is encrypted. Related analysis and simulation experiment verifies that this RFID secure mechanism easily realizes, operates fast and can completely meet the security demand of the RFID systems.

Key words: Radio Frequency Identification(RFID), secure mechanism, chaotic technology, data encryption, Logistic mapping
