【摘要】：移动自组网(Mobile Ad Hoc Networks,MANETs)所面临的Flooding攻击是一种严重DOS攻击行为。然而,现有的针对Flooding攻击的防范技术因不能较好地适应MANETs特性(如有限资源、动态拓扑等)而难以在MANETs网络性能和网络安全之间保持平衡。通过分析移动自组网的时空动态性、网络性能评估与Flooding安全威胁之间的内在关系,提出了一种基于性能评估的Flooding攻击防御技术。通过构建可量化的MANETs安全威胁、防御收益与代价的评估指标体系,实现了基于网络安全和性能平衡的防御及其性能优化方法。仿真实验结果表明,所提出的防御技术可有效地弥补现有移动自组网安全技术存在的一些缺陷,因而能够满足移动自组网特性且适合于实际应用。
[Abstract]:The Flooding attack faced by Mobile Ad Hoc Networks (Manets) is a serious DOS attack. However, it is difficult to maintain a balance between MANETs network performance and network security because the existing technologies for preventing Flooding attacks can not adapt well to MANETs characteristics (such as limited resources, dynamic topology, etc.). By analyzing the temporal and spatial dynamics of mobile ad hoc networks and the relationship between network performance evaluation and Flooding security threats, a Flooding attack defense technology based on performance evaluation is proposed. By constructing a quantifiable evaluation index system of MANETs security threat, defense profit and cost, the defense and performance optimization method based on network security and performance balance is realized. The simulation results show that the proposed defense technology can effectively compensate for the shortcomings of the existing mobile ad hoc network security technology, so it can meet the characteristics of the mobile ad hoc network and is suitable for practical application.
