Authenticache

Hardware-assisted security is emerging as a promising avenue for protecting computer systems. Hardware based solutions, such as Physical Unclonable Functions (PUF), enable system authentication by relying on the physical attributes of the silicon to serve as fingerprints. A variety of PUF designs have been proposed by researchers, with some gaining commercial success. Virtually all of these systems require dedicated PUF hardware to be built into the processor or System-on-Chip (SoC), increasing the cost of deployment in the field.
