摘要
该文从网络安全集体防御机制及其同步分析入手,引入不确定性因子,建立了网络行动同步的改进模型。在此基础上,运用Lyapunov函数分析了网络行动同步的稳定性,提出同步判据,重点分析了系统的边连接概率、网络规模、备用节点数和网络不确定性概率等对同步能力及稳定性的影响,最后给出了仿真验证。理论分析和仿真实验表明,系统的边连接概率、网络规模、备用节点数概率与第2大特征值、最小特征值与第2大特征值之比均呈负相关关系,与网络安全集体防御行动的全局同步稳定和局部同步稳定呈负相关关系。
Based on cyberspace security collective defensive mechanism and its synchronization,uncertainty factors are introduced in the synchronization of cyberspace operation,and the improved synchronization model is established.The stability of cyberspace operation synchronization is analyzed by utilizing Lyapunov function,and synchronization criterions are put forward.What is more,factors that influenced synchronization ability and stability are explored,such as edge connection probability,cyberspace scale,standby elements,and uncertainty probability.Finally,simulations are given.Theoretical research and simulations show that the factors of cyberspace operation synchronization are negatively related with the second eigenvalue and the ratio of minimum eigenvalue to the second eigenvalue,and corresponding negatively related with the cyberspace ecosystem＇s global synchronization stability and local synchronization stability.
