Secure Multiparty Quantum Computation for Summation and Multiplication
As a fundamental primitive, Secure Multiparty Summation and Multiplication can be used to build complex secure protocols for other multiparty computations, specially, numerical computations. However, there is still lack of systematical and efficient quantum methods to compute Secure Multiparty Summation and Multiplication. In this paper, we present a novel and efficient quantum approach to secu...
متن کاملSecure 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 کاملBetter Preprocessing for Secure Multiparty Computation
We present techniques and protocols for the preprocessing of secure multiparty computation (MPC), focusing on the so-called SPDZ MPC scheme and its derivatives. These MPC schemes consist of a so-called preprocessing or offline phase, where correlated randomness is generated that is independent of the inputs and the evaluated function, and an online phase, where such correlated randomness is con...
