A Survey on Perfectly Secure Verifiable Secret-sharing

Abstract

Verifiable Secret-Sharing(VSS) is a fundamental primitive in secure distributed computing. It is used as a building block in several distributed computing tasks, such as Byzantine agreement and secure multi-party computation. In this article, we consider VSS schemes withperfectsecurity, toleratingcomputationally unboundedadversaries. We comprehensively survey the existing perfectly secure VSS schemes in three different communication settings, namely, synchronous, asynchronous, and hybrid setting and provide full details of the existing schemes in these settings. The aim of this survey is to provide a clear knowledge and foundation to researchers who are interested in knowing and extending the state-of-the-art perfectly secure VSS schemes.
