Universally ideal secret-sharing schemes [PDF]

IEEE Transactions on Information Theory, 1994
Summary: Given a set of parties \(\{1, \dots, n\}\), an access structure is a monotone collection of subsets of the parties. For a certain domain of secrets, a secret-sharing scheme for an access structure is a method for a dealer to distribute shares to the parties.

A characterisation of ideal weighted secret sharing schemes

Journal of Mathematical Cryptology, 2015
Beimel, Tassa and Weinreb [SIAM J. Discrete Math. 22 (2008), 360–397] and Farràs and Padró [Lecture Notes in Comput. Sci. 5978, Springer, 2010, 219–236] partially characterised access structures of ideal weighted secret sharing schemes in terms of the ...

Ideal Hierarchical Secret Sharing Schemes [PDF]

Lecture Notes in Computer Science, 2010
Hierarchical secret sharing is among the most natural generalizations of threshold secret sharing, and it has attracted a lot of attention since the invention of secret sharing until nowadays. Several constructions of ideal hierarchical secret sharing schemes have been proposed, but it was not known what access structures admit such a scheme.

Ideal secret sharing schemes on graph-based $3$-homogeneous access structures [PDF]

Transactions on Combinatorics, 2021
‎The characterization of the ideal access structures is one of the main open problems in secret sharing and is important from both practical and theoretical points of views‎. ‎A graph-based $3-$homogeneous access structure is an access structure in which

Implementing Quantum Secret Sharing on Current Hardware [PDF]

Entropy
Quantum secret sharing is a cryptographic scheme that enables the secure storage and reconstruction of quantum information. While the theory of secret sharing is mature in its development, relatively few studies have explored the performance of quantum ...

HCSS-GB and IBESS: Secret Image Sharing Schemes with Enhanced Shadow Management and Visual-Gradient Access Control [PDF]

Entropy
Image protection in privacy-sensitive domains, such as healthcare and military, exposes critical limitations in existing secret image sharing (SIS) schemes, including cumbersome shadow management, coarse-grained access control, and an inefficient storage-

On secret sharing schemes, matroids and polymatroids

Journal of Mathematical Cryptology, 2010
The complexity of a secret sharing scheme is defined as the ratio between the maximum length of the shares and the length of the secret. The optimization of this parameter for general access structures is an important and very difficult open problem in ...

Asymptotically ideal Chinese remainder theorem ‐based secret sharing schemes for multilevel and compartmented access structures

IET Information Security, 2021
Multilevel and compartmented access structures are two important classes of access structures where participants are grouped into levels/compartments with different degrees of trust and privileges.
