An efficient simulation for quantum secure multiparty computation [PDF]
The quantum secure multiparty computation is one of the important properties of secure quantum communication. In this paper, we propose a quantum secure multiparty summation (QSMS) protocol based on (t, n) threshold approach, which can be used in many ...

Generation and Distribution of Quantum Oblivious Keys for Secure Multiparty Computation
The oblivious transfer primitive is sufficient to implement secure multiparty computation. However, secure multiparty computation based on public-key cryptography is limited by the security and efficiency of the oblivious transfer implementation.

Scalable Secure Multiparty Computation [PDF]
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

Secure multiparty computation of a comparison problem. [PDF]
Private comparison is fundamental to secure multiparty computation. In this study, we propose novel protocols to privately determine [Formula: see text], or [Formula: see text] in one execution. First, a 0-1-vector encoding method is introduced to encode a number into a vector, and the Goldwasser-Micali encryption scheme is used to compare integers ...

Secure Multiparty Computation with Minimal Interaction [PDF]
We revisit the question of secure multiparty computation (MPC) with two rounds of interaction. It was previously shown by Gennaro et al. (Crypto 2002) that 3 or more communication rounds are necessary for general MPC protocols with guaranteed output delivery, assuming that there may be t ≥ 2 corrupted parties.

On 2-Round Secure Multiparty Computation [PDF]
Substantial efforts have been spent on characterizing the round complexity of various cryptographic tasks. In this work we study the round complexity of secure multiparty computation in the presence of an active (Byzantine) adversary, assuming the availability of secure point-to-point channels and a broadcast primitive.

Dynamic Decentralized Reputation System from Blockchain and Secure Multiparty Computation
In decentralized environments, such as mobile ad hoc networks (MANETs) and wireless sensor networks (WSNs), traditional reputation management systems are not viable due to their dependence on a central authority that is both accessible and trustworthy ...

Privacy-preserving record linkage in large databases using secure multiparty computation [PDF]
Background Practical applications for data analysis may require combining multiple databases belonging to different owners, such as health centers. The analysis should be performed without violating privacy of neither the centers themselves, nor the ...

A note on secure multiparty computation via higher residue symbols
We generalize a protocol by Yu for comparing two integers with relatively small difference in a secure multiparty computation setting. Yu's protocol is based on the Legendre symbol.

Overcoming collaboration barriers in quantitative trait loci analysis [PDF]
In this issue of Cell Genomics, Choi et al.1 report a novel approach, privateQTL, which leverages secure multiparty computation (MPC) to enable federated expression quantitative trait loci (eQTL) mapping across institutions without compromising data ...
