Secure Multiparty Computation
A function is private if there exists a protocol that is secure; that is, no party can learn any additional information about the other parties’ inputs other than what follows from their own input and the function’s output. Previous studies have investigated multiparty computation with broadcast communication, but broadcast communication does not fully capture all secure multiparty protocols. W...
متن کاملSecure Multiparty Computation
Assume a number of parties want to compute a public function F (x1, . . . , xn) = (y1, . . . , yn). All of them want to get the correct answer, but none of them are willing to expose their secret inputs to other parties. One way to achieve this requirement is to implement the secure multiparty computation protocols. In this paper, we will make a brief introduction to secure multiparty computati...
متن کاملScalable Secure Multiparty Computation
We present the first general protocol for secure multiparty computation which is scalable, in the sense that the amortized work per player does not grow, and in some natural settings even vanishes, with the number of players. Our protocol is secure against an active adversary which may adaptively corrupt up to some constant fraction of the players. The protocol can be implemented in a constant ...
متن کاملScalable and Unconditionally Secure Multiparty Computation
We present a multiparty computation protocol that is unconditionally secure against adaptive and active adversaries, with communication complexity O(Cn)k + O(Dn)k + poly(nκ), where C is the number of gates in the circuit, n is the number of parties, k is the bitlength of the elements of the field over which the computation is carried out, D is the multiplicative depth of the circuit, and κ is t...
متن کاملSecure Multiparty Computation and Secret Sharing
In a data-driven society, individuals and companies encounter numerous situations where private information is an important resource. How can parties handle confidential data if they do not trust everyone involved? This text is the first to present a comprehensive treatment of unconditionally secure techniques for multiparty computation (MPC) and secret sharing. In a secure MPC, each party poss...
