An experimental study of influencing of power supply voltage on characteristics of arbiter physical uncloneable functions (PUF) is presented. Arbiter PUF was implemented with 0,18 um CMOS process of JSC «MERI and Mikron». It was found that systematic process variations negatively impact on PUF uniqueness. Reducing the power voltage to threshold voltage levels improves PUF uniqueness. Besides, precision of power supply noticeably impacts on PUF robustness.
