An analysis of RFID authentication schemes with Secure Object Tracking Protocol for the Internet of Things.

Computer Engineering

Most of the existing tracking protocol aims to increase the visibility of an object in a specific networked RFID system . A “path checker” object tracing and tracking protocol which stores state information to tag and uses key-based hash to perform the information exchange between the tag and the reader. This protocol uses many readers to authenticate and update a tag. Protocol assumes that tags are tamper resistant and capable of anticounterfeit mechanisms but which is invalid for RFID tags and thus it is only secure on a weak advisory model. Also, the path of an object can be checked at the end of the destination .So, we propose a secure object tracking protocol to ensure the visibility and traceability of an object along the travel path to support the Internet of Things (IoT). This protocol is based on radio frequency identification (RFID) system for global unique identification of IoT objects. To ensure secure object tracking, physically unclonable functions are used by the proposed protocol. Here, we modeled the protocol using security protocol description language (SPDL) and simulated SPDL model using automated claim verification tool Scyther. The results show that the proposed protocol is more secure and requires less computation compared to existing similar protocols
