AES Algorithm Applied on Security Protocol of RFID

The radio frequency identification (RFID) system may suffer from serious threats that may result in security problems, which becomes a critical issue for RFID systems and applications. As a consequence, a security protocol for RFID tags is needed to ensure privacy and authentication between each tag and their reader. In order to achieve this purpose, this paper proposes a new encryption security authentication protocol, which Based on the research of The Advanced Encryption Standard, AES algorithm is applied to RFID system to ensure the safety of data transmission. The paper also discusses the hardware implementation of AES algorithm detailed, and uses the basic structure of feedback mode to achieve encryption and decryption operation. The top-down approach to the design of hardware module work. The completion of the hardware describe language of all the module functionality test, And meet the requirements of the protocol RFID.
