摘　　要：拟态防御通过构建动态异构冗余的系统架构达到破坏攻击链的目的。为提高仲裁的效率,并进而改进系统的整体执行能力,针对拟态防御系统的仲裁过程,在多数一致性表决的基础上,提出一种竞赛式的仲裁模型,在不改变仲裁余度的前提下增加执行余度。实验结果表明,与三余度拟态系统相比,该模型能够有效地弥补拟态系统的性能损失。Mimic defense structures the system architecture with dynamic heterogeneous redundancy to damage the attack chain.In order to increase the efficiency of arbitration and further improve the overall executive ability of the system,according to the arbitration of mimic defense system,this paper proposes a competitive arbitration model based on majority consensus voting strategy,to increase the execution redundancy without changing the arbitration redundancy.Experimental results indicate that compared with Triplex mimicry system,the model can effectively compensate for the performance loss of a mimic system.
