This document is a presentation on RFID (radio frequency identification) technology. It discusses the basics of how RFID works, involving tags that can be read by readers from a distance to identify objects. It outlines some security and privacy concerns with RFID, like tracking objects without consent. It then gives examples of applications like supply chain management, toll payment systems, and animal tracking. Finally, it discusses the pros and cons of RFID systems.

Introduction
In last few years RFID technology has become a major
driver for various business like logistics, supply chain
management and acess control
Many of these applications have based on successful
implementations of RFID tags but on reader’s side we
show how semi-passive tags helps implementing and
attacking security enhanced RFID.
It has various security and privacy concerns, which is due
to the inherent vulnerabilities in the architecture of the
RFID system..

What is RFID?
Radio Frequency Identification
Uses Radio Frequency waves to transfer data between a
reader and a tag to identify, categorize, track...
One form of Automatic Identification
RFID is fast reliable and does not require physical sight or
contact between reader/scanner and the tagged item.
Provides unique identification or serial number of an
object (pallets, cases, items, animals, humans
Some of the large companies like Microsoft and Wallmart
are mandating their suppliers to use RFIDs to cut their
warehousing costs and other relating expenses

Why was RFID invented?
Like most technologies used today, RFID got it start from
WWII. The parent technology of RFID is transponder.
Transponders are radio devices that can recieve or send
signals. They are found virtually on all aircrafts and
watercrafts.
In WWII transponders were used as IFF (identify Friend or
Foe) to distinguish Allied Aircraft from enemey ones.

Key Components of RFID system
A RFID system is made up of two parts: a tag or label and
a reader.
RFID tags or labels are embedded with a transmitter and
a receiver.
The RFID component on the tags have two parts: a
microchip that stores and processes information, and an
antenna to receive and transmit a signal.
RFID Reader is also known an interrogator

Conclusion
How it Works?
The tag contains the specific serial number for one specific
object.
To read the information encoded on a tag, a two-way
radio transmitter-receiver called an interrogator or reader
emits a signal to the tag using an antenna.
The tag responds with the information written in its
memory bank.
The interrogator will then transmit the read results to an
RFID computer program.

Security and Privacy challenges
RFID Tag Cloning Attack :cloning is done by forging the
data from an authentic tag generally into a blank tag
Physical Attack: Any kind of tampering to tag
architecture depending upon intention of attacker
Skimming Attack: Usually done by reading the data of tag
without authorization of tag holder
Spoofing Attack: Attacker try to act like a reader inorder
to interrogate tags
Relay Attack: Attacker acts an Man In Middle between
tag and reader
Denial of Services(DOS) Attack: It involves jamming of
operating frequency of communication channel
Clandestine Tracking: It exploits the ubiquitous nature of
the tag, thus making it a very easy attack prone
