PROJECT TITLE :

A Novel Coding Scheme for Secure Communications in Distributed RFID Systems - 2016

ABSTRACT:

Privacy protection is the primary concern when RFID applications are deployed in our daily lives. Due to the computational power constraints of passive tags, non-encryption-based singulation protocols have been recently developed, in that wireless jamming is used. However, the existing personal tag access protocols without shared secrets rely on impractical physical layer assumptions, and therefore they're troublesome to deploy. To tackle this issue, we tend to first redesign the architecture of RFID system by dividing an RF reader into two completely different devices, an RF activator and a trusted shield device (TSD). Then, we have a tendency to propose a novel coding theme, particularly Random Flipping Random Jamming (RFRJ), to shield tags' content. Unlike the past work, the proposed singulation protocol utilizes only the physical layer techniques that are already implemented. Analyses and simulation results validate our distributed architecture with the RFRJ coding theme, that defends tags' privacy against varied adversaries as well as the random guessing attack, correlation attack, ghost-and-leech attack, and eavesdropping.
