摘　　要：针对当前动态异构冗余系统中异构体调度缺乏动态性和仅考虑二阶异构性,导致系统易被攻击者找到共模漏洞从而攻破系统的问题,提出了一种同时考虑执行体高阶异构度和历史信息的异构执行体动态调度算法——基于高阶异构度的负反馈调度算法。该算法首先计算等待池中执行体的高阶异构度矩阵,然后在每次调度执行体时同时考虑历史威胁和异构体间的高阶异构度来确定调度执行体集。实验表明,结合高阶异构度和历史信息的策略使算法获得了动态性和安全性的平衡,且防御能力较先前算法更优秀。At present,most isomer scheduling models in DHR systems only considered second-order isomerism and lack dynamics.In order to solve these problems,a dynamic scheduling algorithm was proposed,which combined heterogene-ity and dynamics by determining a scheduling scheme with maximum scheduling value.The value was obtained by com-bining high-order heterogeneity and historical information.The experimental results show that the proposed algorithm has better defense capabilities than other scheduling algorithms,and its strategy can achieve a balance of dynamics and security.
