SAN JOSE, CA --- Verayo has licensed its Physical Unclonable Functions (PUF) technology to Xilinx, Inc. Xilinx® recently announced that it incorporated Verayo's PUF IP to enhance security in the Xilinx Zynq® UltraScale™+ MPSoC devices.
The silicon manufacturing process has random variations that cannot be controlled, resulting in unique characteristics from chip-to-chip. These variations are within the tolerances built into the design, and do not affect the overall functions of the chip. Physical Unclonable Functions (PUF) are tiny circuits that exploit these chip-unique variations. In the Xilinx Zynq UltraScale+ MPSoC devices, PUF circuits utilize this manufacturing "fingerprint" to generate unique keys that are then used to secure firmware load operation during the boot process.
PUF technology was invented and first implemented at MIT by Prof. Srini Devadas, co-founder of Verayo. Verayo's PUF technology has been used in multiple government and defense programs, as well as consumer products, and has gone through a wide range of military, industrial, and commercial grade testing. Verayo's PUF authentication and key generation technology has been implemented in FPGAs, ASICs, and NFC RFIDs across a wide range of process nodes from 0.18µ to 16nm, with over 40M PUF chips characterized and shipped.
