以Fluhrer,S.,Mantin,I.,Shamir,A.提出的KSA(KeyScheduleAlgorithm)攻击为基础,提出了一种改进的KSA攻击方法。与Fluhrer等提出的KSA攻击相比,新方法具有更高攻击效率。利用这种方法,成功地实现了针对802.11网络链路层安全协议———WEP的攻击,成功地恢复出了原加密密钥。本文详细地描述了这种攻击,同时针对802.11网络存在的安全问题,提出了一些安全建议。
Based on KSA (KeyScheduleAlgorithm) attack proposed by Fluhrer, S., Mantin, I., Shamir, A., an improved KSA attack method is proposed. Compared with the KSA attack proposed by Fluhrer et al., The new method has higher attack efficiency. Using this method, the attack on the link layer security protocol of the 802.11 network, WEP, has been successfully implemented and the original encryption key has been successfully recovered. This article describes this attack in detail, and at the same time addresses some of the security issues that exist in 802.11 networks.
