摘要
摘要:随着网络信息系统的发展，网络病毒扩散方式及免疫策略成为网络安全领域研究的热点之一。该文研究了一类新型混合攻击病毒，并根据其特点将这类病毒定义为“去二存一”型病毒。通过分析新型病毒的攻击方式，构建了“去二存一”混合机制下病毒的SEIQRS信息扩散模型。在此基础上，求解对应系统的平衡点，并运用Routh-Hurwitz判据分析了系统基本再生数R0及其对系统稳定性的影响。最后，仿真验证了模型的有效性和稳定性。

Abstract:With the development of network information system, virus propagation and immunization strategy become one of the hot topics in the field of network security. In this paper, a new virus with hybrid attacking is introduced, which can attack network in two modes. One is to attack and infect the network nodes directly, and the another is to hide itself in the nodes by hiding its viral characteristic. According to its characteristics, this type of virus is defined as " Two-go and One-live” and the corresponding virus propagation model is established. Moreover, the stability of the system is studied by solving the equilibrium points and analyzing the basic reproduction number R0. Numerical simulations are presented to verify effectiveness and stability of the novel model.
Key words:Virus propagation/
