Efficient Secret Sharing for Large-Scale Applications

Abstract

Threshold secret sharing enables distributing a message to n parties such that no subset of fewer than t parties can learn the message, whereas any subset of at least t parties can recover the message. Despite being a fundamental primitive, secret sharing still suffers from one significant drawback, where its message reconstruction algorithm is computationally expensive for large privacy thresholds t. In this paper, we aim to address this significant drawback.
