On alternative approach for verifiable secret sharing

TL;DR

This paper introduces a novel 'free lunch' approach to verifiable secret sharing that aims to provide verification without additional costs, enhancing the practicality of secret sharing schemes.

Contribution

The paper proposes a new method for verifiable secret sharing that eliminates the usual verification overhead, making the process more efficient and accessible.

Findings

The approach enables verification without extra costs.

It simplifies the implementation of verifiable secret sharing.

Potential for broader adoption due to efficiency gains.

Abstract

Secret sharing allows split/distributed control over the secret (e.g. master key). Verifiable secret sharing (VSS) is the secret sharing extended by verification capacity. Usually verification comes at the price. We propose "free lunch", the approach that allows to overcome this inconvenience.
