由于蓝牙系统运行在 2 .4 GHz的公共 ISM频带内 ,所以其安全性一直是研究的热点问题。介绍了一种基于链路层的蓝牙鉴权机制的原理 ,并通过一个应用实例 :篮牙头戴式耳机 ,验证了此机制的有效性和实用性。
Due to the Bluetooth system operating in the 2.4 GHz common ISM band, its security has been a hot issue in research. This paper introduces a principle of Bluetooth authentication mechanism based on link layer, and verifies the effectiveness and practicability of this mechanism through a practical example: Bluetooth headset.
