Single-Input Functionality against a Dishonest Majority: Practical and Round-Optimal

Paper: Single-Input Functionality against a Dishonest Majority: Practical and Round-Optimal. Zhelei Zhou, Bingsheng Zhang, Hong-Sheng Zhou, and Kui Ren. 2024

This work presents a \(1\) round SIF protocol against a dishonest-majority (dealer is honest), assuming preprocessing.
Presents multi-party subfield VOLE.
They show the necessity of using broadcast channels, by formally proving that 1-round SIF is impossible to achieve in the preprocessing model, if there are no broadcast channels available.
