摘　　要：拟态防御是一种基于动态异构冗余架构的新型主动防御技术,具有内在不确定、异构、冗余及负反馈等特性,从而能显著提高系统稳健性和安全性。其中多执行体调度算法是拟态防御技术的关键,其优劣直接影响拟态系统抵抗基于已知或未知漏洞后门攻击的能力。基于此,首先介绍了拟态调度算法技术和目标,然后从调度对象、调度数量及调度时机这3个方面对调度算法研究现状进行了分析总结,最后展望了拟态调度算法未来的研究方向与趋势。Mimic defense is the new active defense technology based on the dynamic heterogeneous redundant architecture.With inherent uncertainty,heterogeneous,redundant and negative feedback features,it can significantly improve the robustness and security of system.Among them,the scheduling algorithm is the key to mimic defense technology,which advantages and disadvantages directly affect the ability of system to resist attacks based on known or unknown vulnerabilities.Based on this,the principle and goal of mimic scheduling algorithm were firstly introduced.Then the state-of-the-art of mimic scheduling algorithms were analyzed and summarized from three aspects,such as scheduling object,scheduling quantity and scheduling timing.Finally,the future research direction and trend of mimic scheduling algorithms were prospected.
