【摘要】：移动自组网(MANETs)的固有特性(如有限资源、动态拓扑等)使其比有线网络更易遭受各种安全威胁。但现有的MANETs安全技术难以有效适应这些特性,尤其是不能在网络性能和网络安全之间保持平衡。在研究MANETs时空动态性及其识别的基础上,首先构建了安全威胁和入侵防御收益与代价的量化评估指标体系,其次提出了一种系统化的MANETs入侵防御系统模型(IDMSLP),最后实现了基于网络安全和性能平衡的防御策略生成与防御性能优化方法。研究结果表明,与现有的IDS系统相比,IDMSLP可有效地克服已有MANETs安全技术存在的缺陷,能更好地应用于MANETs网络。因此,对于MANETs的入侵行为,需要从时空动态性角度并通过构建量化评估指标进行防御。
[Abstract]:The inherent characteristics of Manets (such as limited resources, dynamic topology, etc.) make mobile ad hoc networks more vulnerable to various security threats than wired networks. However, the existing MANETs security technology is difficult to adapt to these characteristics effectively, especially it can not keep a balance between network performance and network security. Based on the study of the spatiotemporal dynamics of MANETs and its identification, a quantitative evaluation index system of security threats and benefits and costs of intrusion prevention is constructed. Secondly, a systematic model of MANETs intrusion prevention system is proposed. Finally, a defense strategy generation and defense performance optimization method based on network security and performance balance is realized. The results show that compared with the existing IDS system, IDMSLP can effectively overcome the shortcomings of the existing MANETs security technology, and can be better applied to MANETs networks. Therefore, the intrusion behavior of MANETs needs to be defended from the point of view of spatiotemporal dynamics and the construction of quantitative evaluation indicators.
