Graphic Codes Made By Two Kinds Of Sun-graphs On Odd-elegant Labelling

Graphical codes are in many areas of current world. Since the ring networks have the properties of fast transmission and high efficiency, so we study the graphical codes on them to prevent hacking. We construct series sun-graphs models which can be applied to the ring networks. The series sun-graphs models are given graphic codes and determined by odd-elegant labellings. We show Topsnut-matrices and text-based passwords of them to encrypt the ring networks, so that a lot of information in ring networks is more secure and more reliable.
