Quantum position verification based on block ciphers
Organisatsiooni nimiCryptography
KokkuvõtePosition verification refers to protocols that allow us to
unambiguously prove that a certain device is located in a certain
position in space (by making use of the fact that the speed of light
is limited and thus from the wrong points in space, responses cannot
come fast enough). Unruh (Crypto 2014) presents a protocol that uses
quantum communication and one application of a hash function. The task
of this thesis is to explore (and prove, and benchmark) improvements
of Unruh's protocol in terms of efficiency: Can we use other (faster)
primitives than hash functions (e.g., block ciphers) inside the
protocol, without losing security?

[All thesis topics should be seen as suggestions. Students are
encouraged to discuss variations of these topics with me. The topics
are designed for master theses, however, interested bachelor students
can contact me to discuss "down-scaled" topics suitable for a bachelor
