摘要： 基于动态异构冗余框架的拟态防御技术是一种主动防御技术,其利用非相似性、冗余性等特征阻断或扰乱网络攻击,以提高系统的可靠性和安全性,其中最大化执行体之间的异构性是提高拟态防御安全效益的关键。文中提出了一种基于网络层次分析法(ANP)和误差反向传播(BP)的执行体异构性量化方法,该方法通过收集和分析不同的异构性影响因素,建立一个多维度的特征矩阵,利用ANP方法综合考虑了各个维度之间的相互依赖关系,对不同维度的特征进行权重分配,同时利用BP神经网络解决ANP方法带来的主观性过强的问题。通过基于ANP-BP的异构性评估模型,能够快速准确有效地筛选出影响异构性最大的因素,为拟态防御执行体异构性评估提供科学依据和技术建议。
