摘要
基于对战场自组织网络中IEEE 802.11 MAC协议的安全性分析,提出一种新的注入攻击方法,与传统注入攻击相比不表现出任何自私攻击行为,可以有效地躲避检测。利用NS2仿真平台搭建了具有分簇结构的战场自组织网络场景,在此环境下进行注入攻击仿真;模拟结果表明,新的注入攻击方法可以降低战场自组织网络数据安全传输的可靠性,攻击节点增多将加大攻击效果。
Based on the analysis of I EEE 802.11 MAC protocol security in battlefield self-organizing networks, a novel injection attack was proposed. Compared with the traditional injection attacks methods, it doesn＇t show any selfish attacking behaviors and can be effectively avoid being detected. Further more, the simulation scenario of cluster-based battlefield self-organizing networks was built by simulation platform NS2, in which injection attacks was simulated. The simulation results show that injection attack could reduce the reliability of data transmission in battlefield self-organizing networks, and the attack effects will be more obvious as the number of attacking nodes is increasing.
