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.
