An Enhanced Secure Mechanism of Low Level Reader Protocol (LLRP) V1.1

LLRP is an interface protocol between RFID Readers and Client. Nowadays, due to the growing number of its adoption and lack of security-related research, this paper proposes an enhanced secure mechanism of Low Level Reader Protocol (LLRP) V1.1 to protect RFID systems from various attacks. This paper first makes an introduction to LLRP and the latest related research, discusses the security vulnerabilities and proposes suggested security services based on the security features of LLRP. It then details the design and implementation of the secured LLRP interaction process as well as its performance evaluation. In the end, this paper simply analyzes the ability of the enhanced secure mechanism of defending against several major security threats. The future work could include further improving the secure mechanism to defend against more attacks and researching for better lightweight encryption and authentication scheme.
