A radio-frequency identification (RFID) tag is a small, inexpensive microchip that emits an identifier in response to a query from a nearby reader. The price of these tags promises to drop to the range of $0.05 per unit in the next several years, offering a viable and powerful replacement for barcodes. The challenge in providing security for low-cost RFID tags is that they are computationally w...

A secure RFID ticket system for public transport is proposed in this paper. It supports security properties including secure authentication, unforgeability, correct billing and privacy and can prevent various attacks. It consists of two protocols, both following three principles necessary for secure RFID ticket system. The first protocol is very efficient and suitable for applications with crit...

Radio frequency identification (RFID) is an emerging technology which brings enormous productivity benefits in applications where objects have to be identified automatically. This paper presents issues concerning security and privacy of RFID systems which are heavily discussed in public. In contrast to the RFID community, which claims that cryptographic components are too costly for RFID tags, ...

In this work we present the first passive attack over the SASI lightweight authentication protocol with modular rotations. This can be used to fully recover the secret ID of the RFID tag, which is the value the protocol is designed to conceal. The attack is described initially for recovering blog2(96)c = 6 bits of the secret value ID, a result that by itself allows to mount traceability attacks...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Radio Frequency Identification (RFID) is technologically one of the most popular batch identification methods of our modern age. The low cost RFID stickers (tags) are gradually replacing traditional paper barcodes. However, the use of tags comes at...

Privacy of RFID systems is receiving increasing attention with the progress of Internet of Things. There are a number of challenges in providing privacy and security in the RFID tag due to the limited computation ability of low-cost RFID tags. Many research works have already been conducted using hash functions and pseudorandom numbers to design the RFID protocol. But few of them involve the de...

Many RFID authentication protocols have been proposed to provide desired security and privacy level for RFID systems. Almost all of these protocols are based symmetric cryptography because of the limited resources of RFID tags. Recently Cheng et. al have been proposed an RFID security protocol based on chaotic maps. In this paper, we analyze the security of this protocol and discover its vulner...

Radio Frequency Identification (RFID) system is a wireless automatic identification using low-cost RFID tags. Promotion of privacy and security in systems has been considered essential due to their usage everyday life. In 2012, Guo-Rui Li et al. Proposed new Efficient Mutual Authentication Protocol for passive (EMAP), that providing confidentiality, un-traceability, efficiency. addition proving the ...

In the last decade RFID technology has become widespread. It can be found in various fields of our daily life. Due to the rapid development more and more security problems were raised. Since tags have limited memory and very low computational capacity a so-called lightweight authentication is needed. Several protocols have been proposed to resolve security and privacy issues in RFID systems. Ho...

Radio Frequency Identification (RFID) tags have a variety of applications in e-banking. For effective utilization of the technology, this should be reinforced toward security holes and attacks. One of the common attacks on RFID systems is RFID tags cloning. In this paper we review cloning attacks in ebanking. We propose solutions based on physical unclonable functions (PUF) and provide a suitab...
