Research on system safety in the case of component failure based on degree correlation

Abstract

Nowadays, complex systems play an irreplaceable role in life, and the security of complex systems has always been the focus of research. In this paper, we focus on the topological characteristics of the network, starting from the degree correlation of the network, and studying the controllability of the network for different network types. For different network datasets, we adopt different security strategies to protect the network. Experiments show that the network controllability of different datasets under different security strategies is very different. Neutral networks and networks with the same configuration have little difference in the performance of each node in the face of network attacks; in the face of network attacks with heterogeneous networks, the security protection strategy of the central node can maintain network security to the greatest extent. Through different security strategies to achieve network controllability, the greatest possible realisation of system security.
