We consider the median estimation problem in a large-scale sensor augmented RFID system. The large-scale deployment of RFID technology has opened the door to innovative ways to integrate RFID and sensor technology. Sensor-tags are tags that can report over 50 types of physical information to a reader. The traditional way to obtain information from sensor-tags is to query each tag. When the numb...

A mobile RFID system is a radio frequency identification technology that allows users to read the information on its tags. When this free reading function is combined with a mobile RFID system featuring radio frequency identification, it may violate an individuals privacy. This is because others may obtain personal information by reading the tags. In addition, user tracking can be a problem, be...

The recent emergence of RFID tags capable of performing public key operations enables a number of new applications in commerce (e.g., RFID-enabled credit cards) and security (e.g., ePassports and access-control badges). While the use of public key cryptography in RFID tags mitigates many difficult security issues, certain important usability-related issues remain, particularly when RFID tags ar...

Paper presents a method for analysis of UHF RFID tags. After a brief overview of RFID system and UHF tags an electromagnetic (EM) simulation of tags in WIPL-D software was conducted. Electrical matching was performed after which tags were excited by a uniform EM wave, induced powers were measured and tag characteristics were compared.

RFID has been identified as one of the cornerstones of the upcoming Internet of Things (IoT) and the focus is moving from conventional RFID towards next generation pervasive networked and interconnected systems. In the future IoT billions of objects are envisioned to report their identity, location, environmental conditions and history over wireless connections. An on-going effort that will sup...

While RFID systems are one of the key enablers helping the prototype of pervasive computer applications, the deployment of RFID technologies also comes with new privacy and security concerns ranging from people tracking and industrial espionage to product cloning and denial of service. Cryptographic solutions to tackle these issues were in general challenged by the limited resources of RFID tag...

Radio Frequency IDentification (RFID) systems are gaining enormous interests in industry due to their vast applications such as supply chain, access control, inventory, transport, health care and home appliances. Although tag identification is the primary security goal of an RFID system, privacy issue is equally, even more important concern in the RFID system because of pervasiveness of RFID ta...

With the increasing popularity of RFID applications, different authentication schemes have been proposed to provide security and privacy protection to users. Most recent RFID protocols use a central database to store the RFID tag data. An RFID reader first queries the RFID tag and returns the reply to the database. After authentication, the database returns the tag data to the reader. In this p...

Low costs of passive UHF RFID tags, as well as their simplicity makes them appropriate for the localization and tracking services in today’s fast-moving, information rich trading networks. However, a few disadvantages of passive RFID technology performances, as a reading range of passive tags and high collision rate during RFID reader-tag communication, still needs quality of service improvemen...

PROTECTING PRIVACY AND ENSURING SECURITY OF RFID SYSTEMS USING PRIVATE AUTHENTICATION PROTOCOLS Md. Endadul Hoque Marquette University, 2010 Radio Frequency IDentification (RFID) systems have been studied as an emerging technology for automatic identification of objects and assets in various applications ranging from inventory tracking to point of sale applications and from healthcare applicati...
