摘要

在蓝牙网络中，没有固定的基础组织，其拓扑结构随时都有可能变化，所有的设备都通过无线方式连接，而且设备间的通信

不一定是直接进行的，可能是由网络中某个设备来转达的，那个设备即在网络中起着路由的作用。在如此的网络中，安全问题是相当复杂的，网络特不容易泄密和遭受攻击。

本文通过对蓝牙技术的介绍，要紧针对蓝牙技术安全性问题，分析了蓝牙系统的安全需求和安全威胁，并对蓝牙的安全机制的框架做了详细介绍。提出了蓝牙安全结构，针对蓝牙系统安全的两种要紧模式即链路级安全模式和服务级安全模式，进行了重点分析。同时，蓝牙技术的无线传输特性使它特不容易受到攻击，蓝牙技术特不设计了快速跳频方案以确保链路稳定，如此增强了系统抗干扰性，并在一定程度上保证了系统的安全性。最后，提出了解决蓝牙安全问题的安全策略。

Abstract

In the bluetooth network, does not have the fixed foundation organization, its topology all has the possibility change as necessary, all equipment all through wireless way connection, moreover correspondence between the equipment not necessarily is carries on directly,

possibly is, this equipment which some equipment conveys by the network in namely in the network is playing the route role.In such network, the security problem is quite complex, the network is specially easy to divulge a secret and to suffer the attack.

This article through to the blue tooth technology introduction, mainly aims at the blue tooth technology secure question, has analyzed the blue tooth system security requirements and the safe threat, and has made the detailed introduction to the blue tooth safety mechanism frame.Proposed the blue tooth safety mechanism, in view of the blue tooth system safety two kind of main patterns is the link level safe mode and the service level safe mode, has carried on the key analysis.At the same time, the blue tooth technology wireless transmission characteristic causes it extremely easily to come under the attack, the blue tooth technology designed the fast-frequency hopping plan to guarantee the link specially to be stable, like this strengthened the system anti-jamming, and has guaranteed

the system security to a certain extent.Finally, proposed solves the blue tooth security problem security policy.

Keywords: Bluetooth; Safe analysis; Security policy; Warning power and encryption; Authorization
