Simple Approach to Realizing Verifiable Secret Sharing for Secure Cloud System

IEEE Access, 2022
In $(k, n)$ threshold secret sharing, a secret is converted into $n$ shares such that any threshold $k$ or more shares allow for the reconstruction of this secret; however, the total storage cost increases.

Boolean-Based (k, n, m) Multi-Secret Image Sharing

Axioms, 2022
Multi-secret image sharing technology shares multiple secret images among shared images for participants and the recovery requires enough shared images for fulfilling the security property.

Matroids and Quantum Secret Sharing Schemes

, 2009
A secret sharing scheme is a cryptographic protocol to distribute a secret state in an encoded form among a group of players such that only authorized subsets of the players can reconstruct the secret.

(k,n) secret image sharing scheme capable of cheating detection

EURASIP Journal on Wireless Communications and Networking, 2018
In a (k,n) threshold secret image sharing scheme, a secret image is encrypted into n image-shadows that satisfy the following: (1) any less than k image-shadows get no information on the image and (2) any k or more image-shadows can reconstruct the ...

Constructions of some secret sharing schemes based on linear codes [PDF]

Известия Саратовского университета. Новая серия: Математика. Механика. Информатика
There 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

Quantum secret sharing without entanglement

, 2002
After analysing the main quantum secret sharing protocol based on the entanglement states, we propose an idea to directly encode the qubit of quantum key distributions, and then present a quantum secret sharing scheme where only product states are ...

Optimal non-perfect uniform secret sharing schemes [PDF]

, 2014
A secret sharing scheme is non-perfect if some subsets of participants that cannot recover the secret value have partial information about it. The information ratio of a secret sharing scheme is the ratio between the maximum length of the shares and the ...
