Visual Secret Sharing Schemes with Cyclic Access Structure for Many Images
We consider a visual secret sharing scheme with cyclic access structure for n secret images and n shares, where two consecutive shares decode one secret image. This secret sharing ...

Dynamic Key Generations for Secret Sharing in Access Structures
In a secret sharing scheme based upon access structures, each group has an authorization and only the participants who stayed in an authorized access structure can recover the sec...

Visual Cryptography for General Access Structure Using Pixel-block Aware Encoding
Multi-pixel encoding is an emerging method in visual cryptography for that it can encode more than one pixel for each encoding run. Nevertheless, in fact its encoding efficiency is...

Secret Sharing Schemes for Very Dense Graphs
A secret-sharing scheme realizes a graph if every two vertices connected by an edge can reconstruct the secret while every independent set in the graph does not get any informatio...
