Powerful Primitives in the Bounded Quantum Storage Model. (arXiv:2302.05724v2 [cs.CR] UPDATED)
cs.CR updates on arXiv.org arxiv.org
The bounded quantum storage model aims to achieve security against
computationally unbounded adversaries that are restricted only with respect to
their quantum memories. In this work, we provide information-theoretic secure
constructions in this model for the following powerful primitives: (1)
CCA1-secure symmetric key encryption, message authentication codes, and
one-time programs. These schemes require no quantum memory for the honest user,
while they can be made secure against adversaries with arbitrarily large
memories by increasing the transmission length sufficiently. (2) CCA1-secure …
