Intrinsic ID is well known for its SRAM-based physically unclonable function (PUF) technology. Due to tiny process variations in the silicon, many of the SRAM cells will always power up containing the same 0 or 1 values (others will vary, but that’s not important). Intrinsic ID employs this feature to generate unique device IDs and cryptographic keys.

Previously, Intrinsic ID’s technology has been presented as hardware IP that has to be built into the silicon. Now, the company has released its Zign X00 series of software products, which can be deployed in any digital device that offers processing capabilities (MCUs, FPGAs, SoCs, etc.), including existing chips that are already on the shelves or in the field. As reported on EEJournal.com, Yes! On-Chip Generation of Post-Quantum Secure IDs and Keys (https://bit.ly/3GzpAHo), all that is required is for a small amount (1KB) of the SRAM that’s already inside the device to be reserved for use as that device’s PUF, while all of the other functions are realized in software code rather than hardware logic gates. The software is provided in the form of a compiled library with associated API for use with any standard processor core (Arm, ARC, MIPS, RISC-V, X86, Xtensa, etc.).
