Abstract
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(τ) | τ ∈ 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 τ of D 2n , A and τ(B) reconstruct the secret image Image(τ). This new VCS is perfect and has contrast 1/(6n 2).
