【摘要】 为了提高内生安全机制调度策略的高效性和鲁棒性，设计了一种调度时机与调度数量动态调整方法.该方法首先提出一种调度触发器，使用工作时长与异常反馈2种属性共同控制调度进程的切换，并综合考虑系统异构、冗余等因素设计调度工作的整体流程；然后利用历史攻击反馈信息对问题建模，针对不同攻击场景设计更新计算公式，以动态调整调度机制工作时长、执行体数量等属性值；最后设计一个仿真模拟器模拟不同攻击场景，比较各算法运行效果.仿真结果表明，该方法通过自适应调整来协调应对复杂的内外部环境，为DHR结构提供较好的安全性；同时提高执行体利用率，减少冗余资源浪费，以较低的系统开销实现较高的安全增益，性能优于其他单一策略，具有较强的实用性.更多还原

【Abstract】 In order to improve the efficiency and robustness of the endogenous security scheduling strategy, a scheduling timing and quantity elastic adjustment method is designed. This method first proposes a scheduling trigger, which uses the two attributes of working time and abnormal feedback to control the switching of scheduling process, and designs the overall flow of scheduling work considering system heterogeneity and redundancy. Then it constructs problem model using historical attack feedback, and designs formulas to dynamically calculate the values for different attack scenarios. Finally, a simulator is designed to simulate different attack scenarios and compare the operation results of each algorithm. Results show that this method can cope with complex internal and external environment through adaptive adjustment, and provide better security for DHR structure. At the same time, it improves the utilization rate of the executor, reduces redundant resource waste, achieves higher security gain with lower system overhead, and outperforms other single strategies, which has strong practicality.更多还原
