论文摘要
蓝牙是一种短期无线技术，可在个人智能手机和播放设备（例如扬声器，耳机和汽车娱乐系统）之间提供音频和数据链接。自2001年推出以来，安全研究人员建议该协议很薄弱，并且容易遭受各种攻击其身份验证，链路管理和加密方案。该领域的主要研究人员表明，可靠的被动蓝牙流量将实现一系列当前假设的攻击的实际应用。通过操纵可用渠道来限制蓝牙的频率跳跃行为，以使蛮力攻击更加有效，这是文献中经常提出的未来研究的途径。本文使用了Ubertooth Project开发的软件定义的无线电工具和自定义硬件，评估了一系列实验中提出的方法。这项工作得出的结论是，以前研究人员提出的机制可能无法提供拟议的改进，而是描述了蓝牙和Wi-Fi技术之间尚未录制的相互作用，这可能会拒绝服务攻击机制。
Bluetooth is a short-range wireless technology that provides audio and data links between personal smartphones and playback devices, such as speakers, headsets and car entertainment systems. Since its introduction in 2001, security researchers have suggested that the protocol is weak, and prone to a variety of attacks against its authentication, link management and encryption schemes. Key researchers in the field have suggested that reliable passive sniffing of Bluetooth traffic would enable the practical application of a range of currently hypothesised attacks. Restricting Bluetooth's frequency hopping behaviour by manipulation of the available channels, in order to make brute force attacks more effective has been a frequently proposed avenue of future research from the literature. This paper has evaluated the proposed approach in a series of experiments using the software defined radio tools and custom hardware developed by the Ubertooth project. The work concludes that the mechanism suggested by previous researchers may not deliver the proposed improvements, but describes an as yet undocumented interaction between Bluetooth and Wi-Fi technologies which may provide a Denial of Service attack mechanism.
