On alternative approach for verifiable secret sharing
The proposed approach works for any underlying secret sharing scheme. It is based on the concept of verification sets of participants, related to authorized set of participants. T...

On Linear Secret Sharing for Connectivity in Directed Graphs
In this work we study linear secret sharing schemes for s-t connectivity in directed graphs. In such schemes the parties are edges of a complete directed graph, and a set of partie...

A Self-healing Key Distribution Scheme with Novel Properties
We improve a secret sharing scheme, which enables users select their personal keys by themselves instead of being distributed by group manager and users can reuse their personal k...

A Verifiable and Detectable Secret Sharing Scheme by Using a New Geometric Approach
Secret sharing schemes are methods for distributing a secret among n participants in such a way that any qualified subsets of participants can recover the secret, and unqualified ...

Visual Secret Sharing Schemes with Cyclic Access Structure for Many Images
We consider a visual secret sharing scheme with cyclic access structure for n secret images and n shares, where two consecutive shares decode one secret image. This secret sharing ...

Detection of Algebraic Manipulation with Applications to Robust Secret Sharing and Fuzzy Extractors
Consider an abstract storage device (G) that can hold a single element x from a fixed, publicly known finite group G. Storage is private in the sense that an adversary does not hav...

Analysis and Design of Multiple Threshold Changeable Secret Sharing Schemes
In a (r, n)-threshold secret sharing scheme, no group of (r - 1) colluding members can recover the secret value s. However, the number of colluders is likely to increase over time...

On the complexity of verifiable secret sharing and multiparty computation
We first study the problem of doing Verifiable Secret Sharing (VSS) information theoretically secure for a general access structure. We do it in the model where private channels b...

Nonperfect Secret Sharing Schemes
: Nonperfect secret sharing schemes NSSs have an advantage such that the size of shares can be shorter than that of perfect secret sharing schemes. This paper shows some basic prop...
