Post-quantum secure time-stamping
Organization
Cryptography
Abstract
A time-stamping service allows a user to obtain a "time-stamp" on a
document which allows them to later prove that they were in possession
of the document already at that point in time. The goal of this thesis
is to study the security of time-stamping in the presence of quantum
attacks - are existing schemes still secure? How to prove their
security? How to improve them if they are not secure?
[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
thesis.]
