Design and Implementation of a Security-Enhanced Baseband System for UHF RFID Tag
This paper presents a security-enhanced baseband system for UH RID tag,which is based on ISO1 000-B protocol. The proposed baseband system consists of the following modules Receiver,Controller, Power Management (PM),Transmitter,Advanced Encryption standard with 12 bits cryptographic key (AES-12),and cyclic Redundancy Check (CRC). AES-12 is the encryption engine,which is designed and implemented properly for low cost requirement. Tag uses AES-12 to protect sensitive data in memory and realize mutual authentication with reader. As the actual length of data transacted between reader and tag is less than 12 bits,a novel data flow is given to enhance security strength. The chip was designed using 0.1 μm CMOS process. Total area of the baseband system is 5μmX3 0μm excluding pads.Power analysis shows that it consumes.μw IV. The chip is under fabrication.
