Hardware-based security primitives, such as PUF, PPUF, and HRNG, often have numerous advantages over classical algorithmic security primitives including much smaller area and energy footprints and higher resiliency against physical and side channel attacks. Currently, the major limitation of hardware-based security primitives is their unreliability with respect to operational and environmental conditions and device aging that is due to their analog nature. We introduce digital hardware securities that preserve or improve all advantages of analog hardware security while eliminating their drawbacks. We focus of digital PUFs and PPUFs. We first introduce foundation and several implementations of digital PUFs. Next, we present several applications including hardware and software protection, side channel elimination, logic obfuscation, and public key cryptography. We conclude by advocating new techniques for creation of conceptually novel hardware-based security primitives.
