Radio Frequency Identification Technology: Applications, Technical Challenges and Strategies
Purpose - The purpose of this paper is to discuss the technology behind RFID systems, identify the applications of RFID in various industries, and discuss the technical challenges of RFID implementation and the corresponding strategies to overcome those challenges.
Design/methodology/approach - Comprehensive literature review and integration of the findings from literature. Findings - Technical challenges of RFID implementation include tag cost, standards, tag and reader selection, data management, systems integration and security. The corresponding solution is suggested for each challenge.
Research limitations/implications - A survey type research is needed to validate the results.
Practical implications - This research offers useful technical guidance for companies which plan to implement RFID and we expect it to provide the motivation for much future research in this area.
Originality/value - As the infancy of RFID applications, few researches have existed to address the technical issues of RFID implementation. Our research filled this gap
Tamper detection in RFID tags, using, fragile watermarking
Security and privacy are one of the two primary concerns with RFID (Radio Frequency Identification) adoption. While the mainstream RFID research is focused on solving the privacy issues, this paper focuses on security issues in general and data tampering in particular. We specifically consider the issue of detecting data tampering on the RFID tags for applications such as data integrity management. To address this issue, we present a novel fragile watermarking scheme, which embeds a fragile watermark (or pattern) in the serial number partition of the RFID tag. This pattern is verified to identify whether or not the data on the RFID tags has been tampered with. The novelty of this watermarking scheme lies in the fact that we have applied watermarking technology to RFID tags; in comparison, most of the existing watermarking schemes are limited to images, or audio or video applications. We term this scheme TamDetect because it is a tamper detection solution. TamDetect is designed such that it can be easily plugged into existing RFID middleware applications. This proposal is one of the first works that integrates watermarking and RFID technologies together. This paper provides a detailed theoretical foundation for the TamDetect solution
Tree Parity Machine Rekeying Architectures
The necessity to secure the communication between hardware components in
embedded systems becomes increasingly important with regard to the secrecy of
data and particularly its commercial use. We suggest a low-cost (i.e. small
logic-area) solution for flexible security levels and short key lifetimes. The
basis is an approach for symmetric key exchange using the synchronisation of
Tree Parity Machines. Fast successive key generation enables a key exchange
within a few milliseconds, given realistic communication channels with a
limited bandwidth. For demonstration we evaluate characteristics of a
standard-cell ASIC design realisation as IP-core in 0.18-micrometer

Tampering in RFID: A Survey on Risks and Defenses
RFID is a well-known pervasive technology, which provides promising opportunities
for the implementation of new services and for the improvement of traditional
ones. However, pervasive environments require strong efforts on all the aspects
of information security. Notably, RFID passive tags are exposed to attacks, since strict
limitations affect the security techniques for this technology. A critical threat for RFIDbased
information systems is represented by data tampering, which corresponds to the
malicious alteration of data recorded in the tag memory. The aim of this paper is to describe
the characteristics and the effects of data tampering in RFID-based information
systems, and to survey the approaches proposed by the research community to protect
against it. The most important recent studies on privacy and security for RFID-based
systems are examined, and the protection given against tampering is evaluated. This
paper provides readers with an exhaustive overview on risks and defenses against data
tampering, highlighting RFID weak spots and open issues
Survey on Lightweight Primitives and Protocols for RFID in Wireless Sensor Networks
The use of radio frequency identification (RFID) technologies is becoming widespread in all kind of wireless network-based applications. As expected, applications based on sensor networks, ad-hoc or mobile ad hoc networks (MANETs) can be highly benefited from the adoption of RFID solutions. There is a strong need to employ lightweight cryptographic primitives for many security applications because of the tight cost and constrained resource requirement of sensor based networks. This paper mainly focuses on the security analysis of lightweight protocols and algorithms proposed for the security of RFID systems. A large number of research solutions have been proposed to implement lightweight cryptographic primitives and protocols in sensor and RFID integration based resource constraint networks. In this work, an overview of the currently discussed lightweight primitives and their attributes has been done. These primitives and protocols have been compared based on gate equivalents (GEs), power, technology, strengths, weaknesses and attacks. Further, an integration of primitives and protocols is compared with the possibilities of their applications in practical scenarios
Formal Computational Unlinkability Proofs of RFID Protocols
We set up a framework for the formal proofs of RFID protocols in the
computational model. We rely on the so-called computationally complete symbolic
attacker model. Our contributions are: i) To design (and prove sound) axioms
reflecting the properties of hash functions (Collision-Resistance, PRF); ii) To
formalize computational unlinkability in the model; iii) To illustrate the
method, providing the first formal proofs of unlinkability of RFID protocols,
in the computational model
Evaluation of Anonymized ONS Queries
Electronic Product Code (EPC) is the basis of a pervasive infrastructure for
the automatic identification of objects on supply chain applications (e.g.,
pharmaceutical or military applications). This infrastructure relies on the use
of the (1) Radio Frequency Identification (RFID) technology to tag objects in
motion and (2) distributed services providing information about objects via the
Internet. A lookup service, called the Object Name Service (ONS) and based on
the use of the Domain Name System (DNS), can be publicly accessed by EPC
applications looking for information associated with tagged objects. Privacy
issues may affect corporate infrastructures based on EPC technologies if their
lookup service is not properly protected. A possible solution to mitigate these
issues is the use of online anonymity. We present an evaluation experiment that
compares the of use of Tor (The second generation Onion Router) on a global
ONS/DNS setup, with respect to benefits, limitations, and latency.Comment: 14 page
