Topological Coding and Topological Matrices Toward Network Overall Security
Bing Yao,Meimei Zhao,Xiaohui Zhang,Yarong Mu,Yirong Sun,Mingjun Zhang,Sihua Yang,Fei Ma,Jing Su,Xiaomin Wang,Hongyu Wang,Hui Sun +11 more
TL;DR: This article introduces Topcode-matrices, which are matrices of order $3\times q$ and differ from popular matrices applied in linear algebra and computer science, and discusses algebraic groups obtained from the above matrices, graph groups, graph networking groups and number string groups for encrypting different communities of dynamic networks.

Text-based Passwords Generated From Topological Graphic Passwords
Bing Yao,Xiaohui Zhang,Hui Sun,Yarong Mu,Yirong Sun,Xiaomin Wang,Hongyu Wang,Fei Ma,Jing Su,Chao Yang,Sihua Yang,Mingjun Zhang +11 more
TL;DR: This article focuses on the transformation between text-based passwords (TB-paws) and Topsnut-gpws, and applies spanning trees of dynamic networks and graphic groups (Tops nut-groups) to approximate the solutions of these two problems.
The relations between network-operation and topological-property in a scale-free and small-world network with community structure
TL;DR: Based on the network-operation, part hub-vertex linking with each other will be helpful for structuring various network models and investigating the rules related with real-life networks.

TL;DR: The dynamical phenomena of complex networks are not easy to model and to characterize by current methods of mathematics, so Newman, Barab´ asi and Watts pointed out the direction of re- searching complex networks by graph theory, which was successfully applied in current investigation ofcomplex networks.
