Unclonable Cryptography with Unbounded Collusions and Impossibility of Hyperefficient Shadow Tomography
Alper Çakan, Vipul Goyal
Quantum no-cloning theorem gives rise to the intriguing possibility of quantum copy protection where we encode a program or functionality in a quantum state such that a user in pos…
Quantum Key Leasing for PKE and FHE with a Classical Lessor
Orestis Chardouvelis, Vipul Goyal, Aayush Jain +1
In this work, we consider the problem of secure key leasing, also known as revocable cryptography (Agarwal et. al. Eurocrypt' 23, Ananth et. al. TCC' 23), as a strengthened securit…
Split-State Non-Malleable Codes and Secret Sharing Schemes for Quantum Messages
Naresh Goud Boddu, Vipul Goyal, Rahul Jain +1
Non-malleable codes are fundamental objects at the intersection of cryptography and coding theory. These codes provide security guarantees even in settings where error correction a…
Computational Quantum Secret Sharing
Alper Çakan, Vipul Goyal, Chen-Da Liu-Zhang +1
Quantum secret sharing (QSS) allows a dealer to distribute a secret quantum state among a set of parties so that certain subsets can reconstruct the secret, while unauthorized subs…
