Post-quantum Plaintext-awareness

ePrint Report: Post-quantum Plaintext-awareness

Ehsan Ebrahimi, Jeroen van Wier

In this paper, we formalize the plaintext-awareness notion
in the superposition access model in which a quantum adversary may
implement the encryption oracle in a quantum device and make superposition queries to the decryption oracle. Due to various possible ways
an adversary can access the decryption oracles, we present six security
definitions to capture the plaintext-awareness notion with respect to each
way of access. We study the relationships between these definitions …
