基于博弈理论的网络安全防御策略研究,大多使用完全信息或静态博弈理论进行攻防过程建模。针对现有攻防博弈模型的局限性,以网络安全防御的蜜罐(Honeypot)技术为研究对象,从动态、不完全信息角度对攻防交互过程建模,提出了网络攻防扩展式博弈模型(Network Attack-Defense Extensive-Form Game Model,NEFGM),给出了扩展式博弈的斯塔克尔伯格均衡(Stackelberg Equilibrium,SE)求解算法,从而在权衡防御成本和收益的前提下提供决策参考。仿真实验分析验证了模型和求解算法的可行性及有效性。
【英文摘要】
Researches on the defense strategy of network security based on game theory mostly use completed information or static game theory to establish the model of offensive and defensive process.In order to solve the limitations of the existing offensive and defensive game model,this paper proposes a network attack-defense game model based on the extensive-form game,which is modeled in a dynamic way and has incomplete information.The honeypot technology of network security is studied,moreover,the solving algorith...
