Silicon Physical Unclonable Functions (SPUFs) are used for extracting unique and random binary signatures from semiconductor chips. This paper introduces the first asynchronous LFSR based PUF; namely, the LFSR-PUF, that can be specifically implemented on a FPGA. The proposed ALFSR-PUF is derived from an asynchronous LFSR that uses D-latch/flip-flops and LUTs on an FPGA to generate a random clock by exploiting the inherent manufacturing process variations of the design primitives. The LFSR-PUF efficiently uses FPGA basic building blocks in each CLB to optimally occupy a very small area (two slices) in the FPGA. Besides design efficiency and area optimization, the challenge-response space is also increased. Consequently, an instantiation of more than one PUF instance is possible within each CLB. Experimental results on Xilinx Spartan-3E FPGA (90 nm) show that the generated signatures are both unique and reliable under varying temperature and voltage conditions.
