Ideal Hierarchical Secret Sharing Schemes
The search of efficient constructions of ideal secret sharing schemes for families of nonthreshold access structures that may have useful applications has attracted a lot of atten...

Characterizing Ideal Weighted Threshold Secret Sharing
Weighted threshold secret sharing was introduced by Shamir in his seminal work on secret sharing. In such settings, there is a set of users where each user is assigned a positive w...

Ideal Secret Sharing Schemes from Permutations
The work presents a new method for the design of ideal secret sharing. The method uses regular mappings that are well suited for construction of perfect secret sharing. The restri...

Hierarchical Threshold Secret Sharing
We consider the problem of threshold secret sharing in groups with hierarchical structure. In such settings, the secret is shared among a group of participants that is partitioned ...

On Ideal Non-perfect Secret Sharing Schemes
Abstract. This paper first extends the result of Blakley and Kabatianski [3] to general non-perfect SSS using information-theoretic arguments. Furthermore, we refine Okada and Ku...
