Introduction
In last few years RFID technology has become a majordriver for various business like logistics, supply chainmanagement and acess control
Many of these applications have based on successfulimplementations of RFID tags but on reader’s side weshow how semi-passive tags helps implementing andattacking security enhanced RFID.
It has various security and privacy concerns, which is dueto the inherent vulnerabilities in the architecture of theRFID system..

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

Why was RFID invented?
Like most technologies used today, RFID got it start fromWWII. The parent technology of RFID is transponder.
Transponders are radio devices that can recieve or sendsignals. They are found virtually on all aircrafts andwatercrafts.
In WWII transponders were used as IFF (identify Friend orFoe) 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 anda reader.RFID tags or labels are embedded with a transmitter anda receiver.The RFID component on the tags have two parts: amicrochip that stores and processes information, and anantenna 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 specificobject.
To read the information encoded on a tag, a two-wayradio transmitter-receiver called an interrogator or readeremits a signal to the tag using an antenna.
The tag responds with the information written in itsmemory bank.
The interrogator will then transmit the read results to anRFID computer program.

Security and Privacy challenges
RFID Tag Cloning Attack :cloning is done by forging thedata from an authentic tag generally into a blank tag
Physical Attack: Any kind of tampering to tagarchitecture depending upon intention of attacker
Skimming Attack: Usually done by reading the data of tagwithout authorization of tag holder
Spoofing Attack: Attacker try to act like a reader inorderto interrogate tags
Relay Attack: Attacker acts an Man In Middle betweentag and reader
Denial of Services(DOS) Attack: It involves jamming ofoperating frequency of communication channel
Clandestine Tracking: It exploits the ubiquitous nature ofthe tag, thus making it a very easy attack prone
