DESCRIPTION:Unclonable Encryption in the Haar Random Oracle Model\n\nEli Goldin | NYU\n\nWe construct unclonable encryption (UE) in the Haar random oracle model\, where all parties have query access to U\,U†\,U∗\,UT for a Haar random unitary U. Our scheme satisfies the standard notion of unclonable indistinguishability security\, supports reuse of the secret key\, and can encrypt arbitrary-length messages. That is\, we give the first evidence that (reusable) UE\, which requires computational assumptions\, exists in "micocrypt"\, a world where one-way functions may not exist.\n\nAs one of our central technical contributions\, we build on the recently introduced path recording framework to prove a natural ``unitary reprogramming lemma''\, which may be of independent interest.
