对抗性仲裁器物理不可克隆函数真的安全吗?
Is adversarial-arbiter physical unclonable function really secure?
摘要
Abstract
Physically unclonable function(PUF)is a promising security primitive for authentication security.Proposing attack models tailored to different PUFs can drive their design improvement and en-hance security.Adversarial-arbiter PUF(A-APUF)is a secure PUF proposed in 2021,claiming to effectively resist modeling attacks.This paper focuses on the A-APUF and proposes a bidirectional-challenge-based attack model.Firstly,bidirectional challenge sequences are applied to the A-APUF to ob-tain bidirectional response sequence,and then the control sequence is calculated.Secondly,the XOR tap coefficients are calculated using the control sequence.Finally,the XOR tap coefficients are used to crack the A-APUF into an arbiter PUF(APUF).The experiments show that this model effectively reduces attack difficulty for both standard and upgraded defense mechanisms of A-APUF,bringing it to the level of an ordinary APUF.Using a conventional feedforward neural network achieves over 90％accuracy with just 1 000 challenge-response pairs for A-APUF.关键词
