Radio Frequency Identification (RFID) system is an
emerging technology for automating object identification. The
Networked RFID System (NRS) is a component of a distributed
object identification network which facilitates automated supply
chain management. It also makes the Internet of Things (IoT)
concept a reality. To increase the business feasibility of NRS
implementation, the system should be able to ensure the visibility
and traceability of the object throughout the chain using a
checker protocol. By doing so, the protocol will check the
genuineness of the object and the genuineness of the object’s
previous travel path on-site. While doing so, the protocol needs to
ensure the security requirement of the system. To this end, we
propose a secure checker protocol for NRS which will use a PUF
(Physically Unclonable Function) and simple cryptographic
primitives. The protocol provides security (protect privacy of the
partners, injection of fake objects, non-repudiation, and
unclonability), visibility and traceability for NRS. It is also
suitable for passive tags.
