A Lightweight Authentication Protocol against Modeling Attacks based on a Novel LFSR-APUF. (arXiv:2305.07254v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Simple authentication protocols based on conventional physical unclonable
function (PUF) are vulnerable to modeling attacks and other security threats.
This paper proposes an arbiter PUF based on a linear feedback shift register
(LFSR-APUF). Different from the previously reported linear feedback shift
register for challenge extension, the proposed scheme feeds the external random
challenges into the LFSR module to obfuscate the linear mapping relationship
between the challenge and response. It can prevent attackers from obtaining
valid challenge-response pairs (CRPs), increasing its …
