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.

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.

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.

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
EPC Network Architecture
No full textThe concept of a “Networked Physical World” originated from the Auto-ID Center, now called the Auto-ID Labs [1]. Such a “World” can be realised with the combination of an automatic identification technology and a ubiquitous computer network that will glue the physical world together. Low cost RFID (Radio Frequency Identification) technology can automate identification of physical objects by providing an interface to link a vast number of objects to the digital domain. Thus, RFID as the enabling technology has paved the way forward for the creation of a “Networked Physical World”. The ability to form a ubiquitous item identification network has a wide range of applications including automation of manufacturing and supply chain management. The previous chapter provided a brief overview of RFID systems. This chapter describes the backend system components formulating a distributed ubiquitous item identification network enabled by the development of automatic identification provided by RFID technology, and examines the flow of tag data, once obtained by an interrogator. The implementation of such an architecture using a web services based model, as well as the impact of the network on supply chain applications, is also investigatedDamith C.
