Secure multi-party computation in large networks [PDF]
Distributed Computing, 2016 We describe scalable protocols for solving the secure multi-party computation (MPC) problem among a large number of parties. We consider both the synchronous and the asynchronous communication models. In the synchronous setting, our protocol is secure against a static malicious adversary corrupting less than a $1/3$ fraction of the parties.

Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Rational actors constantly incorporate information into their decision‐making behavior. Since there is often a time lag between the announcement of a policy and its implementation, an important question arises: when do rational actors incorporate new information into their market behavior, at the announcement or at the implementation of a ...

Modes of Operation Suitable for Computing on Encrypted Data
IACR Transactions on Symmetric Cryptology, 2017 We examine how two parallel modes of operation for Authenticated Encryption (namely CTR+PMAC and OTR mode) work when evaluated in a multiparty computation engine. These two modes are selected because they suit the PRFs examined in previous works.

Food Tastes in the United States: Convergence or Divergence?
Agribusiness, EarlyView.ABSTRACT This study investigates how food consumption tastes have changed in recent decades across the United States. Using NielsenIQ data for over 77 million transactions, there is evidence of divergence in food tastes across regions from 2007 to 2016 and across households of different income, education, and race/ethnicity groups.

Optimally Efficient Multi-Party Fair Exchange and Fair Secure Multi-Party Computation [PDF]
ACM Transactions on Privacy and Security, 2015 Multi-party fair exchange (MFE) and fair secure multi-party computation (fair SMPC) are under-studied fields of research, with practical importance. In particular, we consider MFE scenarios where at the end of the protocol, either every participant receives every other participant’s item, or no participant receives anything. We analyze the

Agribusiness, EarlyView.ABSTRACT Sustainability labels can help support consumers select more socially and environmentally friendly options, thereby enhancing returns for conscientious producers and promoting the transition to a more sustainable food system. However, consumer confusion regarding labels' meaning undermines their effectiveness.

Multi-Party Computation with Omnipresent Adversary [PDF]
, 2009 Secure multi-party computation (MPC) protocols enable a set of n mutually distrusting participants P 1 , ..., P n , each with their own private input x i , to compute a function Y = F (x 1 , ..., x n ), such that at the end of the protocol, all participants learn the correct value of Y , while secrecy of the private inputs is maintained.

Farmers’ Protests in Germany: Media Coverage and Types of Bias
Agribusiness, EarlyView.ABSTRACT The German farmers’ protests of 2024 sparked widespread media coverage and public debate. Yet, media coverage was not always positive, reflecting the media's attention‐seeking and selective focus. Occurrences of farmers blocking media outlets reflected distrust in how their concerns were portrayed.

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 ...
