ePrint Report: A Simple Construction of Quantum Public-Key Encryption from Quantum-Secure One-Way Functions

Khashayar Barooti, Giulio Malavolta, Michael Walter

Quantum public-key encryption [Gottesman; Kawachi et al., Eurocrypt’05] generalizes public-key encryption (PKE) by allowing the public keys to be quantum states. Prior work indicated that quantum PKE can be constructed from assumptions that are potentially weaker than those needed to realize its classical counterpart. In this work, we show that quantum PKE can be constructed from any quantum-secure one-way function. In …
