Two classes of PUFs can be used in HIS systems: those based on specific circuitry and those based on standard, available components. PUFs based on specific circuitry work well in carefully controlled experimental environments, but face significant challenges that limit their commercial viability. These PUFs require costly and time-consuming test silicon and can be incompatible with commercial tool-flows. PUFs based on standard, available components, on the other hand, do not require test silicon and are easily integrated into standard ASIC flows, making them far more suitable for commercial applications. Intrinsic-ID PUFs are memory-based, and have been confirmed to behave in a predictable manner under all relevant stress conditions, including aging, and temperature and voltage variations.The rigorous Intrinsic-ID product-quality release procedure includes accelerated lifetime tests that replicate the effects of decades of aging. This unique quality testing procedure of continuous, fully automated stressing in Philips labs makes use of state-of-the-art, certified test facilities. Intrinsic-ID solutions have been implemented in production silicon and proven to perform under commercial conditions.
