边权重的混合攻击策略

Hybrid Attack Strategy Based on Edge Weight

鉴于当前网络攻击策略多样化和复杂化的现状,提出了以边权重作为度量复杂网络中边重要性的指标,并与传统的边介数度量指标进行了对比分析。通过4种类型的仿真网络,论证了边权重的合理性和有效性,并在边攻击策略的基础上提出了一种混合攻击策略。将新的攻击策略与传统的点攻击策略和边攻击策略进行对比分析,仿真结果表明:所提出的混合攻击策略对网络造成的破坏程度明显大于传统的点、边攻击策略。当网络崩溃时,混合攻击策略的攻击次数几乎为点攻击策略的一半。

For the diversification and complexity of current network attack strategy,edge weight as a measure of the importance of edge in complex network was proposed and compared with the traditional edge betweenness measure. Through four different types of simulation network,the edge weight was demonstrated to be reasonable and effective. Meanwhile a hybrid attack strategy was proposed based on the edge attack strategy. Moreover the new attack strategy was compared with the traditional point attack strategy and edge attack strategy respectively. The simulation results show that the destructiveness of hybrid attack strategy is significantly larger than the traditional point or edge attack strategy. When the network crashes,the attack times of hybrid attack strategy is almost half of the point attack strategy.
