SoK: Secure Computation over Secret Shares

본문 미리보기

Secure multiparty computation (MPC) enables mutually distrustful parties to jointly compute functions over private data without revealing their inputs. A central paradigm in MPC is the secret-sharing-based model, where secret sharing underpins the efficient realization of arithmetic, comparison, numerical, and Boolean operations on shares of private inputs. In this paper, we systematize protocols for these operations, with particular attention to two foundational contributions \cite{ChidaGHIKLN1
