SRAM-based Physical Unclonable Functions leverage inherent manufacturing variations to create unique, unclonable keys for any device.
For many years, silicon Physical Unclonable Functions (PUFs) have been seen as a promising and innovative security technology making steady progress. Today, Static Random-Access Memory (SRAM)-based PUFs have been deployed in hundreds of millions of devices and offer a mature and viable security component that is achieving widespread adoption in commercial products. They are found in devices ranging from tiny sensors and microcontrollers to high-performance Field-Programmable Gate Arrays (FPGAs) and secure elements where they protect financial transactions, user privacy, and military secrets.
