Studies On Rfid Security Authentication Protocol

Radio Frequency Identification is an non-contact automatic identification technology. As the developed of the maturity of communication technology and large scale integrated circuits, RFID technology was gradual rised since Nineties the twentieth century, and its wide range of application challenged our attention.As RFID edge closer towards wide-spread deployment, security issues and privacy problems became a central concern, which was viewed as a primary barrier to the widespread adoption of RFID technology. This paper against the attack model to RFID system, aimed at designing a lightweight security protocol, studied in following aspects:Firstly, we analyzed and summarized the existing RFID security protocol, and designed a hash algorithm based RFID security protocol, then analyzed the security of protocol use the BAN logic. The protocol realized mutual authentication between reader and tag, that satisfied the security and privacy requirement of RFID system.Secondly, the paper designed the digital controller of a security RFID tag chip according to ISO/IEC 15693 and our security protocol, which including the formulation of safety instruction, the allocation of storage space, and the designing of sub-module.At last, the function simulation is executed in Modelsim SE 6.0, and the results showed it can works well.
