基于异构冗余架构的择多表决机制实现了拟态防御系统的容错机制.在拟态通用运行环境(Mimic Common Operating Environment,MCOE)中.由外部表决模块对异构执行体响应数据进行大数表决来实现这一机制.为完善表决机制,提高表决速度,本文提出了基于历史表现安全性和异构置信度的大数表决机制和并行聚类算法.改进的大数表决机制有效地修补了简单大数表决机制存在的无法产生表决结果以及忽视执行体本身安全性和相关性的问题;并行聚类算法解决了表决过程中数据闲置的问题,显著提高了表决速度.此外为了保证数据比对的可靠性,本文设计了针对结构化,非结构化(图像、音频、视频)数据的特定处理流程.

Research on External Voting Mechanism of MCOE

The majority voting mechanism based on heterogeneous redundant architecture realizes the fault tolerance of mimic defense systems. In the Mimic Common Operating Environment (MCOE), the mechanism is achieved after the external voting module performs the majority voting on the response data of heterogeneous executors. To improve the voting mechanism and improve the voting speed, this study proposes a majority voting mechanism based on historical performance security and heterogeneous confidence and a parallel clustering algorithm. The improved majority voting mechanism can effectively tackle the problems of the simple majority voting mechanism that cannot produce voting results and ignore the security of the executors themselves and their correlation. The parallel clustering algorithm solves the problem of idle data in the voting process and significantly improves the voting speed. In addition, this study designs a specific processing flow for structured and unstructured (images, audios, videos) data to ensure the reliability of data comparison.
