A Secure RFID Reader Protocol based on SLRRP

The research on the security of RFID (Radio Frequency Identification) has occupied the attention. Most of previous research results focus on the security and privacy between a RFID tag and a reader. However, the research on the security between a reader and a back-end server leaves much to be desired. And moreover The standard parties of RFID reader protocol, that are EPCglobal Reader Protocol Specification v1.1 (EPCRP) and IETF Simple Lightweight RFID Reader Protocol (SLRRP), simply mentioned that using HTTPS and TLS can be recommended for the security solution of reader protocol. However, they do not consider the properties of various environments like communication channel, computing power of the reader, limitation of hardware, etc. Or even if they give proper consideration of various environments, the security mechanism is supported over specific communication protocol. So, we keenly establish the standard of secure reader protocol which contains authentication protocol, key agreement, message format, etc. In this paper, we introduce the reader protocol standards and raise several problems, and then propose a secure RFID reader protocol which can be satisfied with the security requirements for the reader protocol based on SLRRP. The comparison shows that our protocol adopt the advantages of SLRRP with solving raised security problems.
