PUFs in Security Protocols: Attack Models and Security Evaluations

U. Ruhrmair, M. van Dijk
2013 2013 IEEE Symposium on Security and Privacy  
They reach from a clean, first setting termed the "stand-alone, good PUF model" to stronger scenarios like the "bad PUF model" and the "PUF re-use model".  ...  We argue why these attack models are realistic, and that existing protocols would be faced with them if used in practice.  ...  ACKNOWLEDGEMENTS The authors would like to thank Jürg Wullschleger for enjoyable discussions and his contributions on the bad PUF model and challenge-logging PUFs.  ...

Unconditionally Secure and Universally Composable Commitments from Physical Assumptions [chapter]

Ivan Damgård, Alessandra Scafuro
2013 Lecture Notes in Computer Science  
Besides allowing us to prove feasibility of unconditional UC-security with (malicious) PUFs and stateless tokens, our compiler can be instantiated with any ideal straight-line extractable commitment scheme  ...  Similarly, with stateless tokens, UC-secure commitments are known only under computational assumptions [13, 24, 15] , while the (not UC) unconditional commitment scheme of [23] is secure only in a weaker  ...  Nevertheless, [36] shows that even with malicious PUFs it is possible to achieve UC-secure computations relying on computational assumptions.  ...

A Private Quantum Bit String Commitment

Mariana Gama, Paulo Mateus, André Souto
2020 Entropy  
The protocol remains secure and private (but not composable) if we realize the random oracles as physical unclonable functions (PUFs) in the so-called bad PUF model.  ...  Since then, it was shown in [24] that commitments with unconditional security can be obtained in the malicious PUF model and, in [25] , an unconditional UC commitment in a stronger adversarial model  ...  a computational UC commitment scheme.  ...

From Stateful Hardware to Resettable Hardware Using Symmetric Assumptions [chapter]

Nico Döttling, Daniel Kraschewski, Jörn Müller-Quade, Tobias Nilges
2015 Lecture Notes in Computer Science  
We present two compilers that transform UC-secure protocols in the stateful hardware model into UC-secure protocols in the resettable hardware model.  ...  Universally composable multi-party computation is impossible without setup assumptions.  ...  authors acknowledge support from the Danish National Research Foundation and The National Science Foundation of China (under the grant 61061130540) for the Sino-Danish Center for the Theory of Interactive Computation  ...
