    An Efficient RFID Privacy Scheme

    Radio Frequency IDentification (RFID) is expected to become an 
    important and ubiquitous infrastructure technology. Like many 
    technologies, low-cost RFID will become pervasive in our daily
    lives when affixed to everyday consumer items as “smart labels”.
    While yielding great productivity gains, RFID systems may create
    new threats to the security and privacy of individuals or organizations.
    Particularly important are ensuring anonymity, semantic security,
    indistinguishability, forward security, key privacy etc. Low cost
    implementation is another key RFID requirement.
    Elemental tags are the simplest and cheapest ones of the RFID tags 
    family. These tags are not able to perform cryptographic operations 
    and they are built using from 200 to 2000 gates for security purposes.
    On the other hand, strong privacy is a real need that must be achieved,
    although public key cryptography the best way to tackle the problem 
    is the most expensive. Previous works with elemental tags are vulnerable 
    to attacks like DoS, swapping, cloning etc.  
    To guarantee the privacy of the owners of tags, this research will 
    find out efficient scheme which would also deal with the cost issue. 
    In order to make the scheme efficient, the work will be on the basic 
    or elemental tags. That means, the reader will do all the cryptographic 
    calculations. Moreover, this work will address strong definitions and 
    protocols for RFID privacy into more practical and useful.
