摘要
为实现安全功能,蓝牙为数据的传输定义了服务层强制安全模式和链路层强制安全模式,但由于蓝牙无线局域网拓扑结构的随时变化特性,以及设备间的通信经常由其他设备转达等原因,因而无法确保网络不泄密和免遭攻击.本文首先讨论了蓝牙技术的链路层安全模式,在此基础上重点研究了蓝牙无线局域网交互环境下的一种中间人攻击,并简要提出了抵御这一攻击的一般性策略.
Though Bluetooth defines service level enforced security mode and link level enforced security mode to realize data transmission security, but because of the alterability of Bluetooth wireless networks topological features as well as the reason of the communications between devices relying on conveyance by other device, the network may blow the gaff and be attacked. The safe mode of Bluetooth technology at link layer is discussed first of all. On the basis of that, a man-in-the-middle attack, which uses Bluetooth in a WLAN environment is analyzed emphatically. In the end, the short policy to resist this kind of attacks is put forward.
