A Secure Communication Protocol for EPCglobal Class 1 Generation 2 RFID Systems

In this paper, we introduce a secure communication protocol for tag authentication and data access authorization in EPCglobal Class 1 Generation 2 (EPC GEN-2) RFID systems. The proposed protocol adopts a process-oriented design to exploit the memory space at tag and backend server ends more efficiently. Based on the formal logic proof and protocol analysis, our scheme not only provides data confidentiality and mutual authentication but prevents threats of tag tracing and secrecy disclosure. Moreover, the EPC GEN-2 standard compliance of our protocol greatly increases the possibility of its adoption by RFID systems vendors and industrial customers in practice.
