Abstract: Recently, Radio Frequency Identification (RFID) and Near Field Communication (NFC) systems are found in various user-friendly services that all of us deal with in our daily lives. As these systems are ubiquitously deployed in different authenti-cation and identification applications, inferring information about our behavior will be possible by monitoring our use of them. In order to provide privacy and security requirements of RFID users in novel authentication applications, lots of security schemes have been proposed which have tried to provide secure and untraceable communication for end-users. In this paper, we investi-gate the privacy of three RFID security schemes which have been proposed recently. For privacy analysis, we use the well-known RFID formal privacy model proposed by Ouafi and Phan. We show that all the studied protocols have some privacy drawbacks, making them vulnerable to various traceability attacks. Moreover, in order to overcome all the reported weaknesses and prevent the presented attacks, we apply some modifications in the structures of the studied protocols and propose an improved version of each one. Our analyses show that the modified protocols are more efficient than their previous versions and new modifications can omit all the existing weaknesses on the analyzed protocols. Finally, we compare the modified protocols with some new-found RFID authentication protocols in the terms of security and privacy.
