This paper focuses on an electronic toll collection (ETC) system using radio frequency identification (RFID) technology. Research on ETC has been around since 1992, during which RFID tags began to be widely used in vehicles to automate toll processes [1]. The proposed RFID system uses tags that are mounted on the windshields of vehicles, through which information embedded on the tags are read b...

Security of RFID systems is a very important issue with the increasing of their applications. To achieve secure communications between a reader and a tag in RFID systems, encryption of the communication data is usually performed. However, in case of low-cost RFID tags, it is difficult for them to adopt the well-known encryption algorithms because the tags have very limited resources to implemen...

RFID-tags are becoming very popular tools for identification of products. As they have a small microchip on board, they offer functionality that can be used for security purposes. This chip functionality makes it possible to verify the authenticity of a product and hence to detect and prevent counterfeiting. In order to be successful for these security purposes too, RFID-tags have to be resista...

For RFID tags to gain general acceptance, they will have to offer powerful and flexible privacy mechanisms. After reviewing existing and upcoming privacy mechanisms for RFID privacy, we propose that a key aspect of RFID communication with passive tags, namely its required energy transference from an external antenna, may offer promise when developing privacy mechanisms. We present two proposals...

Radio frequency identification (RFID) system is a wireless automatic identification mechanism. Now, it is widely applied in supply chain management, supermarket checkout process, public transportation, animal identification, the localization and tracking of objects and people, and toll ways. The tag collisions in RFID system is an unavoidable problem. The number of collision in previous tag ant...

Current research in RFID security focuses on basic authentication protocols between a tag and a reader. In this paper, we claim that, in future, different new RFID-based scenarios will play an increasing role. In particular, we propose two new research directions: 1. Multi-Tag Security, and 2. RFID-based Payment. In multi-tag security, multiple tags try to jointly compute an information while u...

adio frequency identification (RFID) is an automatic identification (autoID) technology developed by the Auto-ID Center at the Massachusetts Institute of Technology, relying on storing and remotely retrieving data using devices called RFID tags and readers (Auto-ID Center, 2002; Doyle, 2004; EPC, 2004b; Finkenzeller, 2000; Shepard, 2005). With RFID technology, physical assets will have embedded...

We study security and privacy in deployments of Radio Frequency Identification (RFID) technology and propose novel mechanisms for improving RFID privacy. In the first part of the thesis, we consider two real deployments of RFID technology: library books and electronic passports. For each deployment, we set out security and privacy issues. Then we analyze existing RFID technology in the context ...

Tag collisions can impose a major delay in Radio Frequency IDentification (RFID) systems. Such collisions are hard to overcome with passive tags due to their limited capabilities. In this paper, we look into the problem of minimizing the time required to read a set of passive tags. We propose the novel concept of parallel singulation which, aided by the multiple antennas configuration, interrog...
