The invention relates to a fast regional multiplexing method for multipoint asynchronous attacks. According to the invention, resistance to multi-point poisoning attacks in the field of intelligent transportation is realized. According to the method, an attack pressure calculation model oriented to poisoning attacks is researched in an ISIG grid, and a regional modularity calculation model based on traffic flow pressure and node association degree is constructed. On the basis, an initial community division method based on combination of attack pressure and modularity is provided to cope with multipoint attacks. In order to further strengthen a protection mechanism, an effective strategy for rapid area reuse and new area creation is provided based on a fuzzy processing mechanism of area modularity in a community structure at the previous moment and in combination with the position attribute of an attack point at the current moment. Through fuzzy processing and dynamic community division, the method can quickly adapt to a multi-body asynchronous attack environment, and the robustness of the system is kept.
本发明涉及一种面向多点异步攻击的快速区域复用方法。本发明实现了对智能交通领域多点投毒攻击的抵御。该方法在ISIG网格中研究面向投毒攻击的攻击压力计算模型,构建了基于车流压力和节点关联度的区域模块度计算模型。在此基础上,提出了一种基于攻击压力与模块度结合的初始社区划分方法,以应对多点攻击。为进一步加强防护机制,基于上一时刻社区结构中区域模块度的模糊化处理机制,并结合当前时刻攻击点的位置属性,提出了快速区域复用与新区域创建的有效策略。通过模糊化处理和动态社区划分,本发明能够在多主体异步攻击的环境中迅速适应,并保持系统的鲁棒性。
