Post-quantum secure time-stamping
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?
