RDL-PUF: A Reconfigurable Double-Latch PUF with Multi-Nonlinear Obfuscation against Modeling-Attack
Strong physical unclonable functions (PUFs) are widely used for lightweight device authentication, but their challenge-response mappings are vulnerable to machine-learning modeling attacks. Existing PUFs based on double-latch cells can improve modeling resistance, yet their fixed physical paths limit entropy extraction...
