摘要
安全性能的优劣是蓝牙应用系统至关重要的问题,影响蓝牙安全的方面很多,就此对蓝牙系统的密钥产生过程及数据加密方面进行了比较详细的探讨,对其中出现的危及系统安全的问题进行了分析,发现在蓝牙系统中,由于它的初始化密钥空间太小,因此容易受到蛮力攻击;在初始化阶段,它的密钥交换协议又太简单,容易因为时延的原因而受到重放攻击。在分析了上述的不足之后,通过引入公钥体制和更加安全的密钥交换协议,对存在的问题提出了具体的解决办法。
The security capability is a very important matter of the bluetooth system.The factors that can affect the security of the system are manifold.The authors of this paper makes a detailed on the security capability of the bluetooth system and analyzes the potential problems with the system.The author points out that because of the small value space of the initial key,it is vulnerable to the brute attack and that its key exchange protocol is very susceptible on the beginning phrase to the DOS attack due to time delay in the channel.Finally,the author proposed that the public key scheme be introduced to solve the problem in the bluetooth system.
