A Post-Quantum Interactive Hashing Theorem

Interactive hashing, introduced by Ostrovsky, Venkatesan, and Yung [OVY93], is a building block in many cryptographic protocols, including perfectly hiding commitments from one-way permutations [NOVY92]. Its multi-output generalization is a key ingredient in constructions of statistical zero-knowledge arguments for NP...

A New Monogamy-of-Entanglement Game for Coset States and Its Applications to Copy-Protection, Unclonable Encryption, and Tokenized Signatures

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...
