摘要: 該文從網(wǎng)絡安全集體防御機制及其同步分析入手,引入不確定性因子,建立了網(wǎng)絡行動同步的改進模型。在此基礎上,運用Lyapunov函數(shù)分析了網(wǎng)絡行動同步的穩(wěn)定性,提出同步判據(jù),重點分析了系統(tǒng)的邊連接概率、網(wǎng)絡規(guī)模、備用節(jié)點數(shù)和網(wǎng)絡不確定性概率等對同步能力及穩(wěn)定性的影響,最后給出了仿真驗證。理論分析和仿真實驗表明,系統(tǒng)的邊連接概率、網(wǎng)絡規(guī)模、備用節(jié)點數(shù)概率與第2大特征值、最小特征值與第2大特征值之比均呈負相關關系,與網(wǎng)絡安全集體防御行動的全局同步穩(wěn)定和局部同步穩(wěn)定呈負相關關系。

Abstract: 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 ecosystems global synchronization stability and local synchronization stability.-
