【摘要】：针对低功耗蓝牙易受泛洪攻击的问题,提出了一种连接认证模型,基于该模型设计了低功耗蓝牙泛洪攻击防御方案。方案结合HMAC(hash-based message authentication code)运算速度快与蓝牙通信同步性强的特点,设计检测模块判断通信状态,利用挑战应答的方式设计连接请求认证协议,在蓝牙协议运行前进行主从设备双向认证,过滤掉攻击报文,保证低功耗蓝牙连接建立的安全。安全性分析和实验结果表明,方案能够有效防御泛洪攻击,同时具有较小的存储和计算开销,适合应用于低功耗蓝牙中。
[Abstract]:Aiming at the problem that low power Bluetooth is vulnerable to flooding attack, a connection authentication model is proposed. Based on this model, a low power Bluetooth flooding attack defense scheme is designed. Combined with the characteristics of HMAC (high speed of hash-based message authentication code) operation and strong synchronization of Bluetooth communication), a detection module is designed to judge the communication status, and a connection request authentication protocol is designed by means of challenge response. Two-way authentication of master-slave devices is carried out before the Bluetooth protocol is run, and attack packets are filtered out to ensure the security of low-power Bluetooth connection establishment. The security analysis and experimental results show that the proposed scheme can effectively protect against flooding attack and has less storage and computing overhead, so it is suitable for low power Bluetooth.
