DESCRIPTION
LOCATION-AWARE AND SAFER CARDS: ENHANCING RFID SECURITY AND PRIVACY VIA LOCATION SENSING ABSTRACT In this system, we report on a new approach for enhancing security and privacy in certain RFID applications whereby location or location-related information (such as speed) can serve as a legitimate access context. Examples of these applications include access cards, toll cards, credit cards, and other payment tokens. We show that location awareness can be used by both tags and back-end servers for defending against unauthorized reading and relay attacks on RFID systems. On the tag side, we design a location-aware selective unlocking mechanism using which tags can selectively respond to reader interrogations rather than doing so promiscuously. On the server side, we design a location-aware secure transaction verification scheme that allows a bank server to decide whether to approve or deny a payment transaction and detect a specific type of relay attack involving malicious readers.

LOCATION-AWARE AND SAFER CARDS: ENHANCING
RFID SECURITY AND PRIVACY VIA LOCATION SENSING
ABSTRACT
In this system, we report on a new approach for enhancing security and privacy
in certain RFID applications whereby location or location-related information (such as
speed) can serve as a legitimate access context. Examples of these applications include
access cards, toll cards, credit cards, and other payment tokens. We show that location
awareness can be used by both tags and back-end servers for defending against
unauthorized reading and relay attacks on RFID systems. On the tag side, we design a
location-aware selective unlocking mechanism using which tags can selectively respond
to reader interrogations rather than doing so promiscuously. On the server side, we
design a location-aware secure transaction verification scheme that allows a bank server
to decide whether to approve or deny a payment transaction and detect a specific type
of relay attack involving malicious readers. The premise of our work is a current
technological advancement that can enable RFID tags with low-cost location (GPS)
sensing capabilities. Unlike prior research on this subject, our defenses do not rely on
auxiliary devices or require any explicit user involvement.
EXISTING SYSTEM
Although a variety of security solutions exist, many of them do not meet the
constraints and requirements of the underlying RFID applications in terms of (one or
more of) efficiency, security, and usability. In an attempt to address these drawbacks,
this system proposes a general research direction one that utilizes sensing technologies
to address unauthorized reading and relay attacks in RFID systems without
necessitating any changes to the traditional RFID usage model.

PROPOSED SYSTEM
The proposed work is based on a current technological advancement that enables
many RFID tags with low-cost sensing capabilities. Various types of sensors have been
incorporated with many RFID tag. Intel’s Wireless Identification and Sensing Platform
(WISP) is a representative example of a sensor-enabled tag, which extends RFID beyond
simple identification to in-depth sensing. This new generation of RFID devices can
facilitate numerous promising applications for ubiquitous sensing and computation.
They also suggest new ways of providing security and privacy services by leveraging
the unique properties of the physical environment or physical status of the tag (or its
owner). In this system, we specifically focus on the design of context aware security
primitives and protocols by utilizing sensing technologies so as to provide improved
protection against unauthorized reading and relay attacks.

DESCRIPTIONS
A typical RFID system consists of tags, readers, and/or back-end servers. Tags
are miniaturized wireless radio devices that store information about their
corresponding subject. Such information is usually sensitive and personally identifiable.
For example, a US e-passport stores the name, nationality, date of birth, digital
photograph, and (optionally) fingerprint of its owner. Readers broadcast queries to tags
in their radio transmission ranges for information contained in tags and tags reply with
such information. The queried information is then sent to the server (which may coexist
with the reader) for further processing and the processing result is used to perform
proper actions (such as updating inventory, opening gate, charging toll or approving
payment).

We present two location-aware defense mechanisms for enhanced RFID security
and privacy. First, we show that location information can be used to design selective
unlocking mechanisms so that tags can selectively respond to reader interrogations.
That is, rather than responding promiscuously to queries from any readers, a tag can
utilize location information and will only communicate when it makes sense to do so,
and thus, raising the bar even for sophisticated adversaries without affecting the RFID
usage model. For example, an office building access card can remain locked unless it is
aware that it is near the (fixed) entrance of the building. Similarly, a toll card can remain
locked unless the car is at the toll booth and/or it is traveling at a speed range regulated
by law.

What is IEEE?
The Institute of Electrical and Electronics Engineers or IEEE (read eye-triple-e) is Incorporated in the State of New York, United States. It was formed in 1963 by the merger of the Institute of Radio Engineers (IRE, founded 1912) and the American Institute of Electrical Engineers (AIEE, founded 1884). A membership organization comprised of engineers, scientists and students that sets standards for computers and communications. It is a nonprofit organization with more than 365,000 members in around 150 countries.
The IEEE describes itself as "the world's largest technical professional society -- promoting the development and application of electro technology and allied sciences for the benefit of humanity, the advancement of the profession, and the well-being of our members."
Why IEEE based projects?
It grantees for standard
It assured latest solution for problems
It delivers new patented technologies at an ever-increasing pace
It access world-class technical information provided by the IEEE and cut down your
research time.
