一种蓝牙安全机制的密钥算法改进

A Improved Key Algorithm of Security Mechanism based on Bluetooth

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 analyzes the information security mechanism for Bluetooth, then discusses the algorithm and realization approach of its various portions in detail, including the flaws in the infosec mechanism of bluetooth. Finally, the paper puts forward a new security mechanism based on AES algorithm that could be suitable for high-level security application of bluetooth, and the test results show that the security mechanism can satisfy the application.
