RGB image encryption using SPN with a novel block cipher over simple graph adjacency matrices and Galois fields

Abstract This paper presents a construction of a secure image encryption scheme with graph theory, Galois field, and substitution-permutation network (SPN) for enhanced multimedia data security. First of all, the authors begin by constructing a complete graph with 8 vertices to understand the struct...
