Multiparty Probability Computation and Verification

TL;DR

This paper introduces a multiparty computation protocol enabling parties to generate probability events and perform oblivious transfer using shared anonymized randomness, along with a method to verify correctness without revealing private data.

Contribution

It presents a novel protocol for secure multiparty probability computation and verification that preserves privacy and correctness.

Findings

Protocol allows secure probability event generation

Enables oblivious transfer in multiparty settings

Includes a verification method without revealing private data

Abstract

A multiparty computation protocol is described in which the parties can generate different probability events that is based on the sharing of a single anonymized random number, and also perform oblivious transfer. A method to verify the correctness of the procedure, without revealing the random numbers used by the parties, is proposed.
