Designing of Arbiter PUF for Securing IP and IoT Devices

Now, the world is holding full of smart embedded objects to improve people’s lives, business development and many applications. The use of embedded systems in the expansion of the Internet of things (IoT) is getting increases. Intellectual property (IPs) is used to design complex embedded systems which may be used to build IoT applications. Hardware security is an important aspect while developing IPs and IoT systems. IoT applications also come with serious threats and technical challenges like data security and privacy. The attackers are targeting to theft the data, do the tempering and trying to get control of the IoT system. However, the area and power consumption overheads associated with adding security functions to protect those systems. Moreover, the approaches taken to secure secret information in the desktops and other supervised systems are not satisfactory for embedded and IoT systems. Physical unclonable function (PUF) is one of the ways to achieve hardware security. PUF works on the principle of process variations. PUF generates a unique and random key which is used to secure IPs, IoT applications, RFID, etc. The three types of Arbiter PUF have been implemented on Zedboard (Zynq Evaluation and Development Kit xc7z020clg484-1) FPGA using Xilinx Vivado 2016.1
