Abstract

In Distributed Secret Sharing schemes, secrets are encoded with shares distributed over multiple nodes of a network. Each involved party has access to a subset of the nodes and thus to a subset of the shares and is able to reconstruct a specific secret. Usually, these schemes are evaluated by measuring the required storage overhead, as well as the encoding and decoding complexities. In this paper, we provide new Distributed (multi) Secret Sharing Protocols for

$(k,n)$

(k,n)

-threshold access structures that improve on previous results, characterized by nearly-optimal storage overhead, achieving both storage optimality and a better encoding/decoding complexity. The protocols are also simpler than previous ones and allow for easier encoding.

分布式秘密共享的改进协议

在分布式秘密共享方案中，秘密是用分布在网络多个节点上的共享进行编码的。每个相关方都可以访问节点的子集，从而访问共享的子集，并且能够重建特定的秘密。通常，通过测量所需的存储开销以及编码和解码的复杂性来评估这些方案。在本文中，我们为$（k，n）$（k、n）阈值访问结构提供了新的分布式（多）秘密共享协议，该协议改进了先前的结果，其特征是几乎最优的存储开销，实现了存储优化和更好的编码/解码复杂度。这些协议也比以前的协议更简单，并且允许更容易的编码。
