SoftPUF on FPGAs

Field Programmable Gate Arrays (FPGAs) are widely used for hardware product design and development. FPGAs provide ease of development, flexibility and reduce time to market. Hardware design houses within various companies, government and defense agencies are increasingly using FPGAs to implement logic in their products. Hence, FPGAs house core intellectual property (IP), trade secrets, and other sensitive information. This makes FPGAs a target of attacks - FPGA cloning and over building, FPGA bitstream substitution, and other tampering attacks. Companies, government and defense organizations want to protect their FPGAs, IP and FPGA based systems against such attacks. The Verayo SoftPUF protects FPGAs against these attacks. The SoftPUF includes PUF implementation and logic ideally suited for FPGAs, it can be implemented in existing FPGAs in the market, without requiring any alterations to the FPGA hardware and programming tools.

PUF Programmed on an existing off-the-shelf FPGA

• Use lookup tables, registers, memorie
• No need to add additional circuitry to FPGA die or modify design tool
• Generates FPGA chip-unique signatures
