WebbThis work improves semi-honest secure two-party computation (2PC) over rings, with a focus on the efficiency of the online phase, and proposes an efficient mixed-protocol framework, outperforming the state-of-the-art 2PC framework of ABY. Secure Multi-party Computation (MPC) allows a set of mutually distrusting parties to jointly evaluate a … Webbseveral previous protocols for secure computation in the preprocessing model. For instance, protocols from [2,22,13,23,11] can be easily cast in this framework. We also present useful generalizations of such protocols to broader classes of algebraic computations. 6 A general method for compressing truth-table correlations was recently …

WebbHistory. Special purpose protocols for specific tasks started in the late 1970s. Later, secure computation was formally introduced as secure two-party computation (2PC) in 1982 (for the so-called Millionaires' Problem, a specific problem which is a Boolean predicate), and in generality (for any feasible computation) in 1986 by Andrew Yao.
