针对网络攻防双方在攻防博弈分析中无法对双方的损益情况做出准确判断的问题
将三角模糊数的概念引入到博弈模型
用三角模糊数来表示难以用精确数值表示的攻防双方各策略的损益值
并且提出了基于三角模糊矩阵的博弈算法。通过算法复杂度分析
证明了整个算法的时间复杂度可以满足网络安全评估的需求。实例表明
基于该算法生成的策略可以保证攻击者的最低收益为14.44
而对于防御系统
最优的防御是采取安装软件升级补丁的策略
这样可以大大加强主机系统的安全性。与传统的基于博弈论的安全评估方法相比
引入三角模糊概念更加符合实际应用情况
提高了评估结果的准确性和有效性。
The concept of triangular fuzzy number is introduced into the game model to solve the problem of cannot making accurate judgments on both offense and defense payoffs in game analysis. The payoffs
which are difficult to be described with accurate numbers
are expressed with triangular fuzzy numbers
and the game algorithm based on triangular fuzzy matrix is thus proposed. The complexity analysis verifies the time complexity to meet the requirements of network security assessment. The strategy based on the algorithm can ensure the minimum income of attacker to approach to 14.44; and for the defense system
the best defense strategy that greatly enhances the host system security is to adopt Install Patches. Compared with the traditional security assessments following game theory
introducing the concept of the triangular fuzzy number facilitates suiting the applications and improving the accuracy and validity of assessments.
