文中重点分析了蓝牙的信息安全机制,对其各部分的密钥算法及实现步骤进行了详细的研究与分析,针对蓝牙信息安全体制中存在的不足提出了由AES算法构建的一种新的安全机制,文中通过对新的安全机制的分析与测试,不但实现了对蓝牙安全机制的密钥算法的改进而且不影响蓝牙的通信效率,结果表明新的安全机制能够满足安全性要求较高的蓝牙应用。 This paper focuses on analyzing the information security mechanism of Bluetooth, and makes a detailed research and analysis on its key algorithms and implementation steps. Aiming at the shortcomings in Bluetooth information security system, this paper proposes a new security algorithm based on AES Mechanism. The paper analyzes and tests the new security mechanism, which not only improves the key algorithm of Bluetooth security mechanism but also does not affect the communication efficiency of Bluetooth. The results show that the new security mechanism can meet the Bluetooth requirements of high security application.
