Two-in-One Secret Image Sharing Scheme with Higher Visual Quality of the Previewed Image

open access: yesMathematics, 2022
Secret image sharing (SIS) scheme is a secret image encoding and decoding scheme that reconstructs the secret image only if the number of participants is sufficient. In contrast, inadequate participants gain no information about the secret image.

On polynomial secret sharing schemes.

open access: yesIACR Cryptol. ePrint Arch., 2019
Nearly all secret sharing schemes studied so far are linear or multi-linear schemes. Although these schemes allow to implement any monotone access structure, the share complexity, SC, may be suboptimal - there are access structures for which the gap between the best known lower bounds and best known multi-linear schemes is exponential. There is growing

Robust Secret Image Sharing Scheme Against Noise in Shadow Images

open access: yesIEEE Access, 2021
The (k, n)-threshold secret image sharing scheme is an image protection method, whose security comes partly from precise mathematical calculations, and even a little change in shadow images will lead to a false recovered image.

On the Optimization of Bipartite Secret Sharing Schemes [PDF]

open access: yesDesigns, Codes and Cryptography, 2010
Optimizing the ratio between the maximum length of the shares and the length of the secret value in secret sharing schemes for general access structures is an extremely difficult and long-standing open problem. In this paper, we study it for bipartite access structures, in which the set of participants is divided in two parts, and all participants in ...

Polarization‐Assisted Visual Secret Sharing Encryption in Metasurface Hologram

open access: yesAdvanced Photonics Research, 2021
Secret sharing is an advanced encryption method that distributes the secret information into multiple participants and only the predesigned subsets of authorized participants can recover the secret by gathering their independent subinformation.

On Secret Sharing Schemes, Matroids and Polymatroids [PDF]

open access: yesJournal of Mathematical Cryptology, 2007
Abstract 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 secret sharing.

Fair Verifiable Secret Sharing Driven by Smart Contracts [PDF]

open access: yesJisuanji gongcheng
Unfair issues arise in secret sharing owing to the insufficient consideration given to participants′self-interested behaviors, such as honest participants being unable to reconstruct the shared secret while dishonest participants are able to.
