Design and modelling an attack on multiplexer based physical unclonable function

Abstract

This paper deals with study of the physical unclonable functions and specifically the design of arbiter based PUF (APUF) and extends the work on different types of attacks on the PUF designs to break the security of the device, which includes advanced computational algorithms. Machine learning (ML) based attacks are successful in attacking existing designs. So in this, the resistance of the modified, proposed design of APUF is examined by modelling the attack based on the logistic regression a MLbased algorithm. The design is validated on Basys-3 Artix -7 FPGA board with a part number (xc7a35tcpg236-1). © 2020 Seventh Sense Research Group. All rights reserved.
