摘　　要：[研究目的]为减少有害信息快速扩散造成的负面影响,及时对网络中重要节点实施免疫保护,是一种有效阻断传播的方法。[研究方法]针对多数网络全局信息难以获取或缺失的情况,借助于节点局部结构信息,采用自回避随机游走直接获取网络中桥枢纽节点,以此作为免疫对象实现最优阻断。[研究结果/结论]实验结果表明,相对于熟人免疫以及广泛使用的随机游走算法,新方法具有较高的准确性,同时受感染概率的影响较小,具有很高的稳定性,可以广泛应用于现实网络空间信息防控中。To reduce the negative impact caused by the rapid diffusion of online harmful information,timely implementation of immune protection for important nodes in the network is an effective method to block dissemination.In view of the difficulty in obtaining global information of most networks,an optimal blocking method is proposed.The new method relies on local structural information of nodes and directly seeks bridge hub nodes in the target network by the self-avoiding random walk.Compared with the acquaintance immunization method and the existing widely used random walk methods,the proposed method only relies on the local structure information of every node,has higher accuracy and higher stability,and is less affected by infection probability,which can be widely used in the prevention and control of adverse information dissemination in real cyberspace.
