Privacy Preservation and Mutual Authentication in RFID Systems

Abstract

Identification and tracking of devices and objects has always been helpful in many fields like transportation, tele-medicine, business and supply chain etc. Radio Frequency Identification (RFID) tags are petite, wireless devices attached to objects for the purpose of identification and information exchange. RFID systems is composed of tags, readers and an application system. These tags can be identified by a reader and are useful for tracking and monitoring. RFID tags uses Radio Frequency (RF) for wireless communication which renders these tags vulnerable to wireless security attacks. Implementation of RFID systems faces huge challenges regarding privacy as these tags can be uniquely identified and thereby are subject to tracking by an adversary. In this project a new privacy and mutual authentication scheme has been discussed that uses cryptographic algorithms and can be used in RFID systems to overcome the issues with privacy.
