  • 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 ...
  • Applications of high-capacity crossbar memories in cryptography 

    Rührmair U; Jaeger C; Bator M; Stutzmann M; Lugli P; Csaba G (2011)
    This paper proposes a new approach for the construction of highly secure physical unclonable functions (PUFs). Instead of using systems with medium information content and high readout rates, we suggest to maximize the ...
  • 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 ...
  • Circuit-based approaches to simpl systems 

    Chen Q; Csaba G; Lugli P; Schlichtmann U; Stutzmann M; Rührmair U (2011)
    This paper presents circuit-based approaches to SIMPL Systems (SIMulation Possible, but Laborious Systems), which could be regarded as a "public-key" version of Physical Unclonable Functions. The use of these systems can ...
  • Physical unclonable functions based on crossbar arrays for cryptographic applications 

    Lugli P; Mahmoud A; Csaba G; Algasinger M; Stutzmann M; Ruhrmair U (WILEY-BLACKWELL, 2013)
    Due to their attractive, regular structure and their simple implementation, crossbar arrays have become one major emerging research area in the fields of nano-devices and electronic circuits. This paper discusses novel ...
  • Towards Electrical, Integrated Implementations of SIMPL Systems 

    Ruhrmair U; Chen QQ; Stutzmann M; Lugli P; Schlichtmann U; Csaba G (Springer, 2010)
    This paper discusses strategies for the electrical, integrated implementation of a novel security tool termed SIMPL system, which was introduced in [1]. SIMPL systems are a public key version of Physical Unclonable Functions ...
