One such primitive is the one-time memory (OTM), introduced by Goldwasser, Kalai, and Rothblum [CRYPTO 2008], which is a classical functionality modeled after a non-interactive 1-out-of-2 oblivious transfer, and which is complete for one-time classical and quantum programs. It is known that secure OTMs do not exist in the standard model in both the classical and quantum settings. \r\n\r\nHere, we propose a scheme for using quantum information, together with the assumption of stateless (i.e., reusable) hardware tokens, to build statistically secure OTMs. Via the semidefinite programming-based quantum games framework of Gutoski and Watrous [STOC 2007], we prove security for a malicious receiver, against a linear number of adaptive queries to the token, in the quantum universal composability framework. We prove stand-alone security against a malicious sender, but leave open the question of composable security against a malicious sender, as well as security against a malicious receiver making a polynomial number of adaptive queries. Compared to alternative schemes derived from the literature on quantum money, our scheme is technologically simple since it is of the \"prepare-and measure\" type. We also show our scheme is \"tight\" according to two scenarios."}],"language":[{"iso":"eng"}],"publication_status":"published","external_id":{"arxiv":["1810.05226"]},"main_file_link":[{"url":"https://arxiv.org/abs/1810.05226"}],"user_id":"71541","publication":"Proceedings of the 15th Conference on the Theory of Quantum Computation, Communication and Cryptography (TQC)","publisher":"Leibniz International Proceedings in Informatics (LIPIcs)","citation":{"ieee":"A.
