3 May 2016 | | Abstract: | With the advent of Physical Unclonable Functions (PUFs), PUF-based quantum
authentication systems (QAS) have been proposed for security purposes and
recently proof-of-principle experiment has been demonstrated. As a further step
towards completing the security analysis, we investigate quantum cloning
attacks against PUF-based quantum authentication systems and prove that quantum
cloning attacks outperform the so-called challenge-estimation attacks. We
present the analytical expression of the false accept probability by use of the
corresponding optimal quantum cloning machines and extend the previous results
in the literature. In light of these findings, an explicit comparison is made
between PUF-based quantum authentication systems and quantum key distribution
(QKD) protocols in the context of cloning attacks. Moreover, from an
experimental perspective, a trade-off between the average photon number and the
detection efficiency is discussed in detail. | | Source: | arXiv, 1605.0786 | | Services: | Forum | Review | PDF | Favorites | |
