| Summary: | Physical cryptography is one of the current trends among the existing methods of protecting digital devices from illegal access. Circuit design solutions in physical cryptography are called digital physically unclonable functions (PUFs), which to be implemented ensure the uniqueness, non-reproducibility (non-cloning) of the protected digital device. In addition, PUFs should be efficient as hardware resources. The existing implementations of the arbiter PUF are based on the synthesis of configurable symmetric paths, when each link is a pair of two-input multiplexers providing two configurations of test signal translation: direct and cross. In order to build a single link on FPGA, it is necessary to use two built-in LUT-blocks, providing the implementation of two multiplexers, meanwhile the hardware resources of LUT-blocks are not fully utilized. The article presents a new architecture of symmetric paths of the arbiter PUF, allowing efficient use of hardware resources of LUT-blocks for various FPGA families. |
