Area-Efficient Physically Unclonable Functions for FPGA using Ring Oscillator
FPGA are widely used for applications such as communication and data transfer with the evolved possibilities of hardware attacks, have raised the security concerns in FPGA. The physically unclonable function (PUF) is widely used approach in FPGA for hardware security. This paper proposes an area-efficient ring oscillator (RO) based PUF to secure FPGA. The designed PUFs have been implemented on Artix-7 operating at a 121MHz frequency. The proposed design 2 utilizes 47% lesser LUTs than the conventional design.
