Abstract: To improve the security and privacy problems in Radio Frequency Identification(RFID) tags,a low power UHF RFID security tag baseband in accordance with the independent national protocol(GJB 7377. 1 -2011) is designed. Through studying RFID tags ’ security strategy and comparing plenty of cryptographic algorithms, PRESENT cryptographic algorithm and security protocol are used to ensure tag’ s security. Reuse of several blocks,time-sharing reuses of registers,power management and multiple time regions design are employed to minimize the power consumption of baseband. Experimental results show that the baseband is in accordance with the independent national UHF RFID standard and has security function. The area of the digital baseband is 369. 84 μm × 362. 56 μm,of which the security module takes 36. 5% ,and the power consumption of the baseband is 5. 26 μW.

Key words: Radio Frequency Identification (RFID), PRESENT algorithm, independent standard, security tag;digital baseband, low power consumption
