PHYSICAL UNCLONABLE FUNCTION FOR LOW COST AUTHENTICATION

The design of Physical Unclonable Functions (PUFs) deals to overcome the security issues related to cloning and hacking of the devices. The aim was to develop an efficient and authenticated device for many industrial applications. FPGA and ASIC are the platforms to design the PUFs. To perform an authentication using PUF, Challenge Response Pair (CRPs) is essential and CRPs of the host devices is mapped to all the interfacing devices to check the authentication mechanism. The device generates the responses corresponding to CRPs which can be collected and managed to perform authentication The Proposed Authentication mechanism is implemented through programmable PUF via XILINX software in FPGA Embedded Processor to authenticate with the others devices. The PUFs quality metrics of uniqueness, reliability and robustness is considered while designing the proposed system
