“…Topological authentication is a new technique based on topological coding, a mixed branch of discrete mathematics, number theory, algebraic group, graph theory, and so on. This technology is more and more widely used in real life; for example, the user identity authentication of the smart-phone adopts a graphic password [1,2]. Johnson et al proposed a picture signature password to determine access to computing devices or services [3].…”

The security of passwords generated by the graphic lattices is based on the difficulty of the graph isomorphism, graceful tree conjecture, and total coloring conjecture. A graphic lattice is generated by a graphic base and graphical operations, where a graphic base is a group of disjointed, connected graphs holding linearly independent properties. We study the existence of graphic bases with odd-graceful total colorings and show graphic lattices by vertex-overlapping and edge-joining operations; we prove that these graphic lattices are closed to the odd-graceful total coloring.
