Impact Of The Switching Activity On The Aging Of Delay-Pufs
2017 22ND IEEE EUROPEAN TEST SYMPOSIUM (ETS)(2017)
摘要
Physically Unclonable Functions (PUFs) are mainly used for generating unique keys to identify electronic devices. The reliability of PUFs needs to be assured under a wide variety of environmental conditions and aging mechanisms. In this paper, we evaluate the impact of NBTI and HCI aging on two types of delay-PUFs (arbiter-PUFs and loop-PUFs). The results show that the switching activity has a limited impact on delay chains and a significant impact on the arbiter (RS latch) of the arbiter-PUF.
