Uncloneable Decryption from Quantum Copy Protection. (arXiv:2203.05866v1 [quant-ph])

Uncloneable decryptors are encryption schemes (with classical plaintexts and
ciphertexts) with the added functionality of deriving uncloneable quantum
states, called decryptors, which could be used to decrypt ciphers without
knowledge of the secret key (Georgiou and Zhandry, IACR'20). We study
uncloneable decryptors in the computational setting and provide increasingly
strong security notions which extend the various indistinguishable security
notions of symmetric encryption.

We show that CPA secure uncloneable bit decryptors could be instantiated from
a copy protection scheme (Aaronson, CCC'09) …
