RFID is a leading technology that has been
rapidly deployed in several daily life applications such as
payment, access control, ticketing, and e-passport, which
requires strong security and privacy mechanisms. However,
RFID systems commonly have limited computational capacity,
poor resources and inefficient data management. Hence there
is a demanding urge to address these issues in the light
of some mechanism which can make the technology excel.
Cloud computing is one of the fastest growing segments of
IT industry which can provide a cost effective technology
and information solution to handling and using data collected
with RFID. As more and more information on individuals and
companies is placed in the cloud, concerns are beginning to
grow about just how safe an environment it is. Therefore, while
integrating RFID into the cloud, the security and privacy of
the tag owner must be considered.
Motivated by this need, we first provide a security and
privacy model for RFID technology in the cloud computing. In
this model, we first define the capabilities of the adversary and
then give the definitions of the security and privacy. After that
we propose an example of an RFID authentication protocol
in the cloud computing. We prove that the proposal is narrow
strong private+ in our privacy model.
