Some Multisecret-Sharing Schemes over Finite Fields
Mathematics, 2020 A secret sharing scheme is a method of assigning shares for a secret to some participants such that only some distinguished subsets of these subsets can recover the secret while other subsets cannot.

An ideal hierarchical secret sharing scheme
CoRR, 2020 One of the methods used in order to protect a secret K is a secret sharing scheme. In this scheme the secret K is distributed among a finite set of participants P by a special participant called the dealer, in such a way that only predefined subsets of participants can recover the secret after collaborating with their secret shares. The construction of

Characterisations of Ideal Threshold Schemes [PDF]
Discrete Mathematics & Theoretical Computer Science, 2004 We characterise ideal threshold schemes from different approaches. Since the characteristic properties are independent to particular descriptions of threshold schemes all ideal threshold schemes can be examined by new points of view and new results on ...

Constructions of some secret sharing schemes based on linear codes [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. ИнформатикаThere are perfect and ideal threshold secret sharing schemes, for example, Shamir’s secret sharing scheme. For the case of general secret sharing schemes with an arbitrary access structure, it is possible to construct a perfect scheme for any

Journal of Mathematical Cryptology, 2020 Secret sharing is an important building block in cryptography. All explicit secret sharing schemes which are known to have optimal complexity are multi-linear, thus are closely related to linear codes.

Journal of Mathematical Cryptology, 2013 An n-player -secure robust secret sharing scheme is a (t,n)-threshold secret sharing scheme with the additional property that the secret can be recovered, with probability at least , from the set of all shares even if up to t players provide incorrect ...

Some Ideal Secret Sharing Schemes [PDF]
, 2007 Summary: In a secret sharing scheme, a dealer has a secret. The dealer gives each participant in the scheme a share of the secret. There is a set \(\Gamma\) of subsets of the participants with the property that any subset of participants that is in \(\Gamma\) can determine the secret.
