Study on Security Protocol Analysis and Design Technology for RFID System

In recent years, with the gradual rise of Internet of things, its applications gradually integrate into every corner of people´s daily lives. RFID (Radio Frequency Identification) is the core of the Internet of things technology, which plays a vital role in the development of the Internet of things. Unfortunately, the security risks of RFID are also accompanied by a growing number of. This paper will focus on the security of LLRP released by EPCglobal and design an enhanced secure protocol of LLRP which is consisted of handshake protocol of authentication and integrity verification of the protocol interaction content. Additionally, the encryption will be added to the communication of the whole LLRP protocol for security. The performance evaluation of the enhanced protocol is carried out in the end.
