Systematic Review of Physically Unclonable Functions on SRAMs for Secured Authentication

Better security is essential for IOT devices since more and more devices today are connected and accessing the sensitive data stored in each other. Today’s device authentications in IoT devices are using public and private key cryptography. In this paper, we review the study of Physically Unclonable Functions (PUFs) on embedded SRAMS for secured authentication. The review first categorizes PUFs into categories based on types of devices. Then, we discuss various performance metrics used to evaluate the performance of Static Random-Access Memory Physically Unclonable Functions (SRAM PUFs). This is followed by various methods of improving stability and reliability of the SRAM PUFs before the conclusion.
