Using multiple linear of multilinear map, we propose a simple, non-interactive and effective publicly verifiable secret sharing (PVSS) scheme based on multilinear DiffieHellman assumption (MDH). Up to now, the publicly verifiable of secret sharing is still an issue. In this paper, we set the sharing secret is a multiple linear pairing, we apply the multiple linear property of multilinear map fo...
An (n, t, d, n−t)-arithmetic secret sharing scheme (with uniformity) for Fq over Fq is an Fq-linear secret sharing scheme where the secret is selected from Fq and each of the n shares is an element of Fq. Moreover, there is t-privacy (in addition, any t shares are uniformly random in Fq) and, if one considers the d-fold “component-wise” product of any d sharings, then the d-fold component-wise ...
It has been observed that the contrast values for (2, 3) VSS scheme, (2, 4) VSS scheme, (3, 5) VSS scheme and (4, 5) VSS scheme claimed by Wu and Sun (2013) are incorrect. Since the same values are cited and compared by many other researchers in their works, we have calculated and presented the correct values of contrast in this note.
A Visual Cryptography (VC)-based system for sharing multiple secret images is proposed. Several weighted transparencies are generated so that people can reveal multiple secret images by stacking qualified subsets of some transparencies together. The transparency with relatively larger weight decides which secret image will be revealed. The proposed method has the following characteristics: deco...
The idea of secret sharing is to start with a secret, divide it into pieces called shares, which are then distributed amongst participants by the dealer. Only certain authorized subsets of participants can reconstruct the original secret. Applications for secret sharing schemes seem to be getting more important nowadays. For many circumstances, secret sharing has to provide more flexibility and...
A novel verifiable secret sharing method for Verifiable secret sharing (VSS) in halftone image based on linear block code with a parity check matrix is proposed. The proposed method, which not only verifies a secret image but also introduces multiple shadows for multiple users. The proposed method adopts forward error correction code (FEC) strategy based on property of linear block codes. There...
A secret sharing scheme starts with a secret and then derives from it certain shares (or shadows) which are distributed to users. The secret may be recovered only by certain predetermined groups. In case of compartmented secret sharing, the set of users is partitioned into compartments and the secret can be recovered only if the number of participants from any compartment is greater than a fixe...
