Public and industry concerns over food safety have grown considerably over the last decade. Food safety has traditionally been viewed as a “cost of business” (Littlefield, 2006) and, as a result, perceived and positioned as the voluntary responsibility of companies. However, this perception is changing as stricter legislation and industry standards are entered into force and require that compan...

This report is written as part of the course TDDC03 Information Security at Linköping Institute of Technology. It aims to give an introduction to RFID, point out the current and future uses of the technology and to evaluate and discuss the technology from a perspective of information security and privacy with focus on new arising concerns.

This book presents various security aspects in RFID and sensor networks. Each chapter represents a self-sufficient, independent paper, and the topics are not formally bound together by means of e.g. an introduction or an overview of the debated topics. The editors have chosen and arranged the discussed topics in such a way, however, as to give a good overview of the security challenges in resou...

RFID-based public transport ticketing systems rely on widespread networks of RFID readers that locate the user within the transport network in real time to be able to verify whether he can travel at that time with the ticket he holds. This paper presents a system that uses that same RFID-based location information to give the user navigation indications depending on his current location, provid...

RFID authentication on large numbers of tags or tag groups has attracted many researchers’ attention as an extension of initial one-or-two-tags scenarios. Due to demands of RFID application in supply chain, various proofs are proposed in the purpose of solving existing problems of grouping tags identification. However, it is proved that verifiers in these proofs are not aware of abnormal relati...
