Authenticated communication from quantum readout of PUFs
Quantum Readout of Physical Unclonable Functions (PUFs) is a recently introduced method for remote authentication of objects. We present an extension of the protocol to enable the authentication of data: a verifier can check if received classical data was sent by the PUF holder. We call this modification QR-d or, in the case of the optical-PUF implementation, QSA-d. We discuss how QSA-d can be ...
متن کاملSecurity of Quantum-Readout PUFs against quadrature based challenge estimation attacks
The concept of quantum-secure readout of Physical Unclonable Functions (PUFs) has recently been realized experimentally in an optical PUF system. We analyze the security of this system under the strongest type of classical attack: the challenge estimation attack. The adversary performs a measurement on the challenge quantum state in order to learn as much about it as he can. Using this knowledg...
متن کاملSecurity analysis of Quantum-Readout PUFs in the case of challenge-estimation attacks
Quantum Readout PUFs (QR-PUFs) have been proposed as a technique for remote authentication of objects. The security is based on basic quantum information theoretic principles and the assumption that the adversary cannot losslessly implement arbitrary unitary transformations on a K-dimensional state space, with K ‘large’. We consider all possible attacks in which the adversary bases his response...
متن کاملSecurity analysis of Quantum-Readout PUFs in the case of generic challenge-estimation attacks
Quantum Readout PUFs (QR-PUFs) have been proposed as a technique for remote authentication of objects. The security is based on basic quantum information theoretic principles and the assumption that the adversary cannot efficiently implement arbitrary unitary transformations. We analyze the security of QR-PUF schemes in the case where each challenge consists of precisely n quanta and the dimens...
متن کاملQuantum readout of Physical Unclonable Functions: Remote authentication without trusted readers and authenticated Quantum Key Exchange without initial shared secrets
Physical Unclonable Functions (PUFs) are physical structures that are hard to clone and have a unique challenge-response behaviour. The term PUF was coined by Pappu et al. in 2001. That work triggered a lot of interest, and since then a substantial number of papers has been written about the use of a wide variety of physical structures for different security purposes such as identification, aut...
