Abstract :
This paper deals with design of Physical Unclonable Functions (PUFs) based on FPGA. The goal was to propose a cheap, efficient and secure device identification or even a cryptographic key generation based on PUFs. Therefore, a proposal of a ring oscillator (RO) based PUF producing more output bits from one RO pair is presented. 24 Digilent Basys 2 FPGA boards were tested and statistically evaluated indicating suitability of the proposed design for device identification.
