Contagion Effects of Heterogeneous Cyber Risk on Network Security and Systemic Stability

This repository contains the code and data-generation procedures used in the paper: *Contagion Effects of Heterogeneous Cyber Risk on Network Security and Systemic Stability*, No external dataset is required. All numerical results are generated directly by the provided scripts from synthetic network instances. The repository implements both exact Stackelberg equilibrium computations and analytical approximations of optimal defense strategies under heterogeneous cyber risk. Network topologies and model parameters can be modified directly within the figure scripts to reproduce or extend the experiments reported in the paper..本仓库收录了论文《异构网络风险的传染效应对网络安全与系统稳定性的影响》（Contagion Effects of Heterogeneous Cyber Risk on Network Security and Systemic Stability）所使用的代码与数据生成流程。无需依赖外部数据集，所有数值结果均可通过提供的脚本基于合成网络实例直接生成。本仓库同时实现了异构网络风险场景下的精确斯塔克尔伯格均衡（Stackelberg equilibrium）计算与最优防御策略的解析近似求解。用户可直接在绘图脚本中修改网络拓扑与模型参数，以复现或拓展论文中报道的相关实验。
