摘要:

嗅探攻击是一种常见且隐蔽性很强的网络攻击方式,这种攻击方式对通信数据的机密性造成了严重威胁,然而传统的防御手段受制于网络攻防对抗的严重不对称性,难以有效应对这种威胁。文章提出了一种面向SDN数据层的双虚假IP地址动态跳变技术,首先利用双虚假IP地址破坏通信数据在空间维度上的关联性,然后通过周期性IP地址跳变破坏通信数据在时间维度上的关联性,从而提高嗅探攻击者重组通信数据的难度以及成本。抗攻击有效性分析以及仿真实验表明,文章所提技术在提高抗嗅探攻击能力的同时,能保证较低的CPU消耗和通信时延。

Abstract:

Sniffing attack is a common and highly concealed network attack, and it poses a serious threat to the confidentiality of communication data. However, the traditional defense means are limited by the serious asymmetry of the network offensive and defensive countermeasures, and it is difficult to deal with this threat effectively. The dynamic hopping technology of double bogus IP address for SDN data layer was proposed. Firstly, the double bogus IP address was used to destroy the spatial correlation of communication data. Secondly, the correlation of communication data was destroyed in time dimension by periodic IP address hopping, to increase the level and cost of sniffing the attacker’s recombination of communication data. The analysis of anti-attack effectiveness and simulation experiments results show that the technology can improve the ability of anti-sniffing attack, and it can also ensure the lower CPU consumption and communication delay.

Key words: sniffing attack, moving target defense, IP hopping, SDN
