Concretely efficient secure multi-party computation protocols: survey and more
Security and Safety, 2022 Secure multi-party computation (MPC) allows a set of parties to jointly compute a function on their private inputs, and reveals nothing but the output of the function. In the last decade, MPC has rapidly moved from a purely theoretical study to an object

Multi-party Computation with Hybrid Security [PDF]
, 2004 It is well-known that n players connected only by pairwise secure channels can achieve multi-party computation secure against an active adversary if and only if ...

AntNest: Fully Non-Interactive Secure Multi-Party Computation
IEEE Access, 2018 In this paper, we focus on the research of non-interactive secure multi-party computation. At first, we propose a fully homomorphic non-interactive verifiable secret sharing (FHNVSS) scheme.

Secure multi-party quantum conference and XOR computation [PDF]
quantum Information and Computation, 2021 Quantum conference is a process of securely exchanging messages between three or more parties, using quantum resources. A Measurement Device Independent Quantum Dialogue (MDI-QD) protocol, which is secure against information leakage, has been proposed (Quantum Information Processing 16.12 (2017): 305) in 2017, is proven to be insecure against intercept-

An equational approach to secure multi-party computation [PDF]
Proceedings of the 4th conference on Innovations in Theoretical Computer Science, 2013 We present a novel framework for the description and analysis of secure computation protocols that is at the same time mathematically rigorous and notationally lightweight and concise. The distinguishing feature of the framework is that it allows to specify (and analyze) protocols in a manner that is largely independent of time, greatly simplifying the

On Security Notions for Multi-Party Computation
, 2022 Die meisten Sicherheitsbegriffe, die heutzutage benutzt werden, stammen aus den 1980ern. Doch durch ein seitdem besseres Verständnis der Theorie stellt sich die Frage, ob sie nicht weiterentwickelt werden können. Ein begrenzender Faktor sind hierbei sogenannte Unmöglichkeitsbeweise, die mathematisch beweisen, welche Sicherheitsgarantien nicht erfüllt ...

Social rational secure multi‐party computation [PDF]
Concurrency and Computation: Practice and Experience, 2013 SUMMARYRational party is a new kind of parties who behave neither like honest parties nor like malicious adversaries. The crux point of rational party is the definition of the utility function, as rational parties only care about how to maximize their utility.

Privacy-preserving machine learning based on secure four-party computations
Безопасность информационных технологий, 2022 The paper is devoted to the analysis of privacy-preserving machine learning systems based on the concept of secure four-party computations. The advantages of the four-party computations over the two- and three-party computations are analyzed.
