Line 37: == Quantum-accessible Random Oracles == [[Post-quantum cryptography]] studies quantum attacks on classical cryptographic schemes. As a random oracle is an abstraction of a [[hash function]], it makes sense to assume that a quantum attacker can access the random oracle in [[quantum superposition]].<ref name=Bon+11>{{cite conference \| author = Dan Boneh, Özgür Dagdelen, Marc Fischlin, Anja Lehmann, Christian Schaffner, and Mark Zhandry \| title = Random oracles in a quantum world \| year = 2011 \| pages = 41–69 \| publisher = Springer \| doi = 10.1007/978-3-642-25385-0_3 \| arxiv = 1008.0931}}</ref>. Many of the classical security proofs break down in that quantum random oracle model and need to be revised. == See also ==
