A State-Separating Proof for Yao's Garbling Scheme
Secure multiparty computation enables mutually distrusting parties to compute a public function of their secret inputs. One of the main approaches for designing MPC protocols are garbled circuits whose core component is usually referred to as a garbling scheme. In this work, we revisit the security of Yao's garbling scheme and provide a modular security proof which composes the security of multiple layer garblings to prove security of the full circuit garbling. We perform our security proof in the style of state-separating proofs (ASIACRYPT 2018).
