    • Analog circuits for physical cryptography 

      Chen Q; Csaba G; Ju X; Natarajan S; Lugli P; Stutzmann M; Schlichtmann U; Rührmair U (IEEE, 2009)
      This paper presents circuit designs to be used as 'public-key' Physical Uncloneable Functions. We will introduce two specially designed circuits: 'skew' memories and massively parallel analog processor arrays (CNNs). We ...
    • Application of mismatched cellular nonlinear networks for physical cryptography 

      Csaba G; Ju X; Ma Z; Chen Q; Porod W; Schmidhuber J; Schlichtmann U; Lugli P; Rührmair U (IEEE, 2010)
      This paper proposes the use of Cellular Non-Linear Networks (CNNs) as physical uncloneable functions (PUFs). We argue that analog circuits offer higher security than existing digital PUFs and that the CNN paradigm allows ...
    • The bistable ring PUF: A new architecture for strong physical unclonable functions 

      Chen Q; Csaba G; Lugli P; Schlichtmann U; Rührmair U (IEEE, 2011)
      This paper introduces a new architecture for circuit-based Physical Unclonable Functions (PUFs) which we call the Bistable Ring PUF (BR-PUF). Based on experimental results obtained from FPGA-based implementations of the ...
    • Characterization of the bistable ring PUF 

      Chen Q; Csaba G; Lugli P; Schlichtmann U; Rührmair U (EDA Consortium, 2012)
      The bistable ring physical(ly) unclonable function (BR-PUF) is a novel electrical intrinsic PUF design for physical cryptography. FPGA prototyping has provided a proof-of-concept, showing that the BR-PUF could be a promising ...
