An Analysis of Authentication for Passive RFID Tags
نویسندگان
چکیده
RFID (Radio Frequency Identification) tags have become pervasive for identifying objects, people and pets, automated payment and theftdeterrents. However, assurance of tag identity has not been built into the RFID environment. Privacy by means of encryption can prevent the data from being human readable but cannot stop a clone being created. This paper considers recent approaches that have been proposed to breach this gap. These include PUF’s (Physically Unclonable Functions), cryptography, digital signatures and radio fingerprints. This paper contributes a critical analysis of current approaches in order to identify requirements for RFID tag authentication, focusing on passive RFID tags used for product authentication.

Game-Based Cryptanalysis of a Lightweight CRC-Based Authentication Protocol for EPC Tags
The term "Internet of Things (IoT)" expresses a huge network of smart and connected objects which can interact with other devices without our interposition. Radio frequency identification (RFID) is a great technology and an interesting candidate to provide communications for IoT networks, but numerous security and privacy issues need to be considered. In this paper, we analyze the security and ...
متن کاملSecure Symmetric Authentication for RFID Tags
The project ART proposes to enhance passive RFID (Radio Frequency Identification) tags with cryptographically secure authentication. Starting with a short introduction into common RFID systems with passive tags, we present a motivation why secure authentication with standardized symmetric crypto algorithms for RFID tags is necessary for many applications. We demonstrate vulnerabilities of curre...
متن کاملPAP: A privacy and authentication protocol for passive RFID tags
Passive Radio Frequency Identification (RFID) tags, due to their ability to uniquely identify every individual item and low cost, are well suited for supply chain management and are expected to replace barcodes in the near future. However, unlike barcodes, these tags have a longer range in which they are allowed to be scanned, subjecting them to unauthorized scanning by malicious readers and to...
متن کاملPassive Attack Against the M2AP Mutual Authentication Protocol for RFID Tags
In this paper, we present a passive attack for finding out the secrets used in MAP (Minimalist Mutual Authentication Protocol), which is an authentication protocol between RFID tags and RFID readers. We describe an algorithm that breaks the protocol after eavesdropping a few consecutive rounds of communication. After two eavesdropped runs of the protocol, the attacker can learn the identificati...
متن کاملSecure and Lightweight Authentication Protocol for Mobile RFID Privacy
A mobile RFID system is a radio frequency identification technology that allows users to read the information on its tags. When this free reading function is combined with a mobile RFID system featuring radio frequency identification, it may violate an individuals privacy. This is because others may obtain personal information by reading the tags. In addition, user tracking can be a problem, be...
