【摘要】：随着社交网络的普及,社交蠕虫已经成为了威胁社会的主要隐患之一.这类蠕虫基于拓扑信息和社会工程学在因特网中快速传播.先前的学者们对社交蠕虫的传播建模与分析主要存在两个问题:网络拓扑的不完整性和传播建模的片面性;因而导致对社交蠕虫感染规模的低估和人类行为的单一化建模.为了解决上述问题,本文提出了社交蠕虫传播仿真模型,该模型使用分层网络能更准确地抽象社交逻辑层与实际物理层之间的关系,以及利用人类移动的时间特性能更全面地刻画社交蠕虫的传播行为.实验结果表明,该仿真模型揭示了用户行为、网络拓扑参数以及不同的修复过程对社交蠕虫传播造成的影响.同时,文中对社交蠕虫的传播能力做出了定性分析,为网络防御提供了重要的理论支持.
[Abstract]:With the popularity of social networks, Social worms have become one of the main threats to society. These worms spread rapidly on the Internet based on topology information and social engineering. Previous scholars have mainly modeled and analyzed the propagation of social worms. Two problems: the incompleteness of network topology and the one-sidedness of propagation modeling; Therefore, it leads to the underestimation of the scale of social worm infection and the simplification of human behavior. In order to solve the above problems, a simulation model of social worm propagation is proposed in this paper. The model can more accurately abstract the relationship between the social logic layer and the actual physical layer by using the hierarchical network, and can describe the propagation behavior of the social worm more comprehensively by using the time characteristics of human movement. The experimental results show that, The simulation model reveals the influence of user behavior, network topology parameters and different repair processes on the propagation of social worms. At the same time, the propagation ability of social worms is analyzed qualitatively. It provides important theoretical support for network defense.
