Post-quantum secure bit commitments

Organization

Abstract
Commitment schemes are one of the central primitives in
cryptography. When security against quantum computers is to be
considered, however, many existing constructions are not known to be
secure any more. In particular, constructions based on weaker
assumptions such as the "short integer solution" problem lead to
efficient and secure protocols in the classical setting, but their
quantum security is not known! The task of the thesis is to generalize
existing solutions to the quantum setting, come up with the required
assumptions, and to prove their 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
thesis.]
