Pseudorandom (Function-Like) Quantum State Generators: New Definitions and Applications
Prabhanjan Ananth, Aditya Gulati, Luowen Qian +1
Pseudorandom quantum states (PRS) are efficiently constructible states that are computationally indistinguishable from being Haar-random, and have recently found cryptographic appl…
Post-Quantum Zero-Knowledge with Space-Bounded Simulation
Prabhanjan Ananth, Alex B. Grilo
The traditional definition of quantum zero-knowledge stipulates that the knowledge gained by any quantum polynomial-time verifier in an interactive protocol can be simulated by a q…
A Note on Copy-Protection from Random Oracles
Prabhanjan Ananth, Fatih Kaleoglu
Quantum copy-protection, introduced by Aaronson (CCC'09), uses the no-cloning principle of quantum mechanics to protect software from being illegally distributed. Constructing copy…
On the Feasibility of Unclonable Encryption, and More
Prabhanjan Ananth, Fatih Kaleoglu, Xingjian Li +2
Unclonable encryption, first introduced by Broadbent and Lord (TQC'20), is a one-time encryption scheme with the following security guarantee: any non-local adversary (A, B, C) can…
