Pseudorandomness in the (Inverseless) Haar Random Oracle Model
Prabhanjan Ananth, John Bostanci, Aditya Gulati +1
We study the (in)feasibility of quantum pseudorandom notions in a quantum analog of the random oracle model, where all the parties, including the adversary, have oracle access to t…
Revocable Encryption, Programs, and More: The Case of Multi-Copy Security
Prabhanjan Ananth, Saachi Mutreja, Alexander Poremba
Fundamental principles of quantum mechanics have inspired many new research directions, particularly in quantum cryptography. One such principle is quantum no-cloning which has led…
Cryptography in the Common Haar State Model: Feasibility Results and Separations
Prabhanjan Ananth, Aditya Gulati, Yao-Ting Lin
Common random string model is a popular model in classical cryptography. We study a quantum analogue of this model called the common Haar state (CHS) model. In this model, every pa…
Unclonable Secret Sharing
Prabhanjan Ananth, Vipul Goyal, Jiahui Liu +1
Unclonable cryptography utilizes the principles of quantum mechanics to addresses cryptographic tasks that are impossible classically. We introduce a novel unclonable primitive in…
Simultaneous Haar Indistinguishability with Applications to Unclonable Cryptography
Prabhanjan Ananth, Fatih Kaleoglu, Henry Yuen
Unclonable cryptography is concerned with leveraging the no-cloning principle to build cryptographic primitives that are otherwise impossible to achieve classically. Understanding…
A Note on the Common Haar State Model
Prabhanjan Ananth, Aditya Gulati, Yao-Ting Lin
Common random string model is a popular model in classical cryptography with many constructions proposed in this model. We study a quantum analogue of this model called the common…
