Signatures From Pseudorandom States via -PRFs
Mohammed Barhoush, Amit Behera, Lior Ozer +2
Different flavors of quantum pseudorandomness have proven useful for various cryptographic applications, with the compelling feature that these primitives are potentially weaker th…
Protecting Quantum Procrastinators with Signature Lifting: A Case Study in Cryptocurrencies
Or Sattath, Shai Wyborski
Current solutions to quantum vulnerabilities of widely used cryptographic schemes involve migrating users to post-quantum schemes before quantum attacks become feasible. This work…
Encryption with Quantum Public Keys
Alex B. Grilo, Or Sattath, Quoc-Huy Vu
It is an important question to find constructions of quantum cryptographic protocols which rely on weaker computational assumptions than classical protocols. Recently, it has been…
Redesigning Bitcoin's fee market
Ron Lavi, Or Sattath, Aviv Zohar
The Bitcoin payment system involves two agent types: Users that transact with the currency and pay fees and miners in charge of authorizing transactions and securing the system in…
