Design, Implementation, and Evaluation of Bluetooth Security

Bluetooth is a recently proposed protocol for local wireless communication and has become a de facto standard for short-range ad hoc radio connections. Security concern is one of the most important problems delaying the mass adoption of Bluetooth. This article provides a study on the security issues behind the Bluetooth standard. After a overview of the general Bluetooth protocol, a security framework is introduced for the description of the Bluetooth security layout. Then both link-level and service-level security schemes are discussed in detail on the basis of the framework. Some weaknesses of the Bluetooth security strategies are analysed, together with potential risks and possible attacks against the vulnerabilities. Corresponding countermeasures are also proposed in order to improve the Bluetooth security.
