Research of Bluetooth Security Manager

The Bluetooth specification includes security features at the link level. It supports authentication and encryption. However it has many limits. This paper introduces the service-level enforced security mode of Bluetooth. And then, we investigate the method of how to realize this mode by using Bluetooth Security Manager. Five classifications of different service security levels and three classifications of different device security levels are defined to provide the manager more free management. We implemented an access control strategy at the service-level. By adopting this measure, we can ensure the more security for Bluetooth services.
