| Abstract(in English) | A new construction of visual cryptography scheme (VCS) with dihedral group access structure for two shares and many secret images is proposed. Let D_<2n> be a dihedral group of order 2n, and let {Image(T)|T∈D_<2n>} be 2n secret images corresponding to D_<2n> In a VCS with dihedral group access structure, two shares (two transparencies) A and B are constructed so that for any element T of D_<2n>, A and T(B) reconstruct the secret image Image(T). This new VCS is perfect and has contrast 1/(6n^2). On the other hand, if we apply simple method to this VCS, we can construct the same VCS with contrast 1/(8n^2). |
