On secret sharing schemes, matroids and polymatroids [PDF]
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 ...

Novel Threshold Changeable Secret Sharing Schemes Based on Polynomial Interpolation. [PDF]
PLoS ONE, 2016 After any distribution of secret sharing shadows in a threshold changeable secret sharing scheme, the threshold may need to be adjusted to deal with changes in the security policy and adversary structure.

On Converting Secret Sharing Scheme to Visual Secret Sharing Scheme [PDF]
EURASIP Journal on Advances in Signal Processing, 2010 Traditional Secret Sharing (SS) schemes reconstruct secret exactly the same as the original one but involve complex computation. Visual Secret Sharing (VSS) schemes decode the secret without computation, but each share is m times as big as the original ...

Advance Sharing of Quantum Shares for Classical Secrets
IEEE Access, 2022 Secret sharing schemes for classical secrets can be classified into classical secret sharing schemes and quantum secret sharing schemes. Classical secret sharing has been known to be able to distribute some shares before a given secret. On the other hand,

IoT-Applicable Generalized Frameproof Combinatorial Designs
IoT, 2023 Secret sharing schemes are widely used to protect data by breaking the secret into pieces and sharing them amongst various members of a party. In this paper, our objective is to produce a repairable ramp scheme that allows for the retrieval of a share ...

Reusing Shares in Secret Sharing Schemes [PDF]
The Computer Journal, 1994 A (t, w) threshold scheme is a method for sharing a secret among w shareholders so that the collaboration of at least t shareholders is required in order to reconstruct the shared secret. This paper is concerned with the re-use of shares possessed by shareholders in threshold schemes.

Multi Secret Image Sharing Scheme of General Access Structure with Meaningful Shares
Mathematics, 2020 A Multi Secret Image sharing scheme can share several secret images among certain participators securely. Boolean-based secret sharing schemes are one kind of secret sharing method with light-weighted computation compared to the previous complex ...

Applying cheating identifiable secret sharing scheme in multimedia security
EURASIP Journal on Image and Video Processing, 2020 In (k,n) secret sharing scheme, one secret is encrypted into n shares in such a way that only k or more shares can decrypt the secret. Secret sharing scheme can be extended into the field of multimedia that provides an efficient way to protect ...
