摘要
为了应对恶意代码对智能配电网的威胁,提出了一种基于网络功能虚拟化蜜网的智能配电终端主动防御策略优化模型,首先构建了智能配电网防御方和恶意用户攻击方之间的博弈对抗模型;然后利用复制动力学方程获得了智能配电网蜜网防御方和恶意用户攻击方的渐近稳定策略,进一步获得智能配电网防御方的演化稳定策略,从而实时搜集和分析恶意用户数据.仿真结果验证了模型的有效性,同时与传统蜜网在智能配电网终端上的防御性能对比,结果表明该方法具有更好的防御性能.
A network function virtualization honeynet-based active defense strategy optimization model is proposed,which is of great significance to counter malicious code,against the threat of malicious code to intelligent distribution network.Firstly,the game model between the defense party of intelligent distribution network and the attacker of malicious users is constructed.Then,by using the replication dynamics,the asymptotic stability strategy of the honeynet defender and malicious user attacker of the intelligent distribution network is obtained,and the evolutionary stability strategy is further obtained.Theoretical analysis shows that the defense party of intelligent distribution network based on virtual honeynet of network functions will collect and analyze malicious user data in real time.The simulation results verify the effectiveness of the model.The experimental results are used to analyze and compare the defense performance of the method proposed and that of the traditional honeynet on the intelligent distribution network terminal,which shows that the method in this paper has better defense performance.
