Towards Unclonable Cryptography in the Plain Model

arXiv:2311.16663v3 Announce Type: replace-cross
Abstract: By leveraging the no-cloning principle of quantum mechanics, unclonable cryptography enables us to achieve novel cryptographic protocols that are otherwise impossible classically. Two most notable examples of unclonable cryptography are quantum copy-protection and unclonable encryption. Most known constructions rely on the quantum random oracle model (as opposed to the plain model). Despite receiving a lot of attention in recent years, two important open questions still remain: copy-protection for point functions in the plain model, which …
