A Family of Dunces: Trivial RFID Identification and Authentication Protocols

Gene Tsudik

Abstract: Security and privacy in RFID systems is an important and active research area. A number of challenges arise due to the extremely limited computational, storage and communication abilities of a typical RFID tag. This paper describes a step-by-step construction of a family of simple protocols for inexpensive untraceable identification and authentication of RFID tags. This work is aimed primarily at RFID tags that are capable of performing a small number of inexpensive conventional (as opposed to public key) cryptographic operations. It also represents the first result geared for so-called {\em batch mode} of RFID scanning whereby the identification (and/or authentication) of tags is delayed. Proposed protocols involve minimal interaction between a tag and a reader and place very low computational burden on the tag. Notably, they also impose low computational load on back-end servers.
