Anil Kumar Kurra, Usha Rani Nelakuditi · 2019
Physical Unclonable Functions (PUFs) are extensively used to generate the cryptographic keys from the Integrated circuits(ICs),by utilizing the uncontrollable and unavoidable process variations during fabrication process. Arbiter PUFs are emerged to be a one of the strong delay based PUFs having exponential number of challenges and used in commercial and critical security applications. In this paper we proposed 8-stage decoder-multiplexer based arbiter PUP, simulated on cadence spectre using CMOS 90nm technology and measured its security metrics such as reliability(92.56%), uniqueness(48%) and uniformity(47.36%) respectively.
