英文摘要	The security of real networks is facing serious challenges and is harder than ever. We propose an idea of "topological structure + number theory" for designing new passwords. By means of graph theory we define a twin odd-graceful tree T = T-1 circle T-2 obtained by identifying a certain vertex of T-1 with a certain vertex of T-2 together. We prove that some particular trees (key-models) can have their associated trees (lock-models) under the concept of twin odd-graceful trees. Trees having set-ordered odd-graceful labellings T-1 with their associated trees T-2 can produce certain twin odd-graceful trees such that these twin odd-graceful trees are odd-graceful.; National Natural Science Foundation of China [61309015, 61163054, 61363060]; CPCI-S(ISTP); 565-568
