PUF (Physical Unclonable Function)

PUFenc is designed to protect external flash memory and its stored assets.
The IP provides asset encryption, such as a learning model for AI or firmware for the chip with a local key from the PUF.
It adds an additional layer of security by avoiding using the global key, which is a shared key among ICs after the chip leaves the manufacturing floor.

The vPUF® IP, powered by Via PUF (Physically Unclonable Function) technology, provides a unique silicon fingerprint for inborn identity function, essential for the Root of Trust in security applications

A physical unclonable function, or PUF, is a "digital fingerprint" that serves as a unique identity for a semiconductor device such as a microprocessor
PUFs are based on physical variations which occur naturally during semiconductor manufacturing, which makes it possible to differentiate between otherwise identical semiconductors
The PUF IP consists of PUF array and control logic

Secure storage without the use of any non volatile memory
No external key provisioning required
Does not require costly SRAM blocks
Proven reliability regarding voltage, temperature and aging with error probability much lower than 10-9

Proven “Soft” PUF implementation for AMD/Xilinx FPGAs, part of the FPGA configuration file
Offers FPGA users a cryptographic technology to secure their own keys and to authenticate devices and communications between them on networks.
Enables remote “brownfield” installation of hardware-based security
