Lightweight cryptography for low cost RFID
No full textSecurity and privacy concerns as well as the need for security services to enable the development of novel applications using low cost RFID have been illustrated in previous Chapters, and in particular various proposals made to address issues regarding information security and end-user privacy have been discussed in Chapter 6. However, some of these ideas are not practicable for secure low-cost RFID on account of their demand for circuit size and operational power while others fail to meet various security and privacy objectives adequately. The solutions presented have not considered: aspects unique to low cost RFID, system performance requirements and consequences and practicability of implementation in a system wide context. This chapter aims to propose a number of practicable solutions based on lightweight cryptography that address the security objectives and privacy goals outlined in Chapter 6 and are based on the low cost RFID framework outlined therein. The proposed solutions are then evaluated for their merits using the evaluation framework developed in Chapter 8. © 2008 Springer-Verlag Berlin Heidelberg.Damith C. Ranasingh
Introduction from the editors
No full textThis introduction describes the structure of the book, and in particular how it is divided into sections and chapters. It gives an outline of what can be found in each chapter, and gives a description of the origin and structure of the organisation known as the Auto-ID Laboratories whose members have studied the anti-counterfeiting problem and have provided the material for this book. © 2008 Springer-Verlag Berlin Heidelberg.Damith C.

An Evaluation Framework
No full textThere are various solutions expounded upon to address security vulnerabilities and privacy violations of low cost RFID systems. This paper will formulate a framework for defining the problem space around low cost RFID systems to enable the engineering of solutions and for evaluating those solutions for their effectiveness in the contest of networked low cost RFID systems. © 2008 Springer-Verlag Berlin Heidelberg.Damith C.

Addressing Insecurities and Violations of Privacy
No full textRFID systems, and indeed other forms of wireless technologies, are now a pervasive form of computing. In the context of security and privacy, the most threatening (to privacy) and vulnerable (to insecurity) are the ‘low cost RFID systems’. The problems are further aggravated by the fact that it is this form of RFID that is set to proliferate through various consumer goods supply chains throughout the world. This is occurring through the actions of multinational companies like Wal-Mart, Tesco, Metro UPS and of powerful government organizations such as the United States DOD (Department Of Defence) and FDA (Food and Drug Administration). This paper examines the vulnerabilities of current low cost RFID systems and explores the security and privacy threats posed as a result of those vulnerabilities. The paper will also formulate a framework for defining the problem space constructed around low cost RFID systems, and consider the challenges faced in engineering solutions to overcome the defencelessness of low cost RFID systems. Security issues beyond and including interrogators will not be considered as such concerns may be easily resolved using existing technology and knowledge, and because interrogators are powerful devices where complex encryption and decryption operations may be performed using either the embedded systems, DSPs, or using hardware implementation of encryption engines on a FPGA device onboard a reader.Damith C.

Networked RFID systems
No full textA combination of Radio Frequency Identification technology and ubiquitous computing are revolutionising the manner in which we look at simple objects. Radio Frequency Identification (RFID) allows RFID labeled objects to be identified at a distance without physical contact, and ubiquitous computing provides a virtually connected environment for the objects. RFID labels are frequently referred to as the next generation barcodes. RFID Systems provide increased productivity, efficiency, convenience and many advantages over bar codes for numerous applications, especially global supply chain management. RFID labeling has a number of advantages over conventional bar code systems. The optics based bar code systems could be rendered useless by common everyday environments containing dirt, dust, smoke, grease, condensation and by misorientation and misalignment. Furthermore bar codes are subject to fraudulent duplication and counterfeiting with minimal effort. While there is a googol of information on Radio Frequency Identification systems, most of which arose in the last decade, it is important to identify concepts and operating principles and to present views on modern RFID systems. This chapter will provide an overview, however brief, of modern RFID systems.Peter H. Cole and Damith C. Ranasingh
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
