In a secret sharing scheme, is distributed among several participants in such way that only any authorized subset of able to recover the secret. So far, security many schemes has been based on hardness some mathematical problems, as discrete logarithm and factorization. These problems can be solved polynomial time using Shor?s algorithm for quantum computer. this paper, we propose an efficient ...
Visual Cryptography comes under cryptography domain. It deals with encrypting and decrypting of visual information like pictures, texts, videos etc. Multi Secret Image Sharing (MSIS) scheme is a part of visual cryptography that provides a protected method to transmit more than one secret images over a communication channel. Conventionally, transmission of a single secret image is possible over ...
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...
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.
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...
