Handling Authentication and Detection Probability in Multi-tag RFID Environment

Subhasish Dhal and Indranil Sengupta

Abstract: In Radio Frequency Identification (RFID) technology, an adversary may access classified information about an object tagged with RFID tag. Therefore, authentication is a necessary requirement. Use of multiple tags in an object increases the detection probability and simultaneously ensures availability of multiple resources in the form of memory and computability. Authentication process in multi-tag arrangement may increase the traffic between reader and object and/or decrease the detection probability. Therefore the challenge is to keep intact the detection probability without increasing the traffic. Existence of multiple number of tags helps to distribute the authentication responsibility for an object among multiple number of tags. In this paper, we assume that an object is attached with multiple number of active tags and in each session a randomly selected tag is responsible for authentication process. The detection probability is intact since an active tag within the range of reader can be an inter-mediator.
