2. Abstract

Bluetooth will facilitate wireless Local Area Networking in which networks of different hand held mobile computing terminals can communicate and exchange data, even on the move when there is no line-of-sight between those devices. I have attempted to review all the major aspects of Bluetooth security implementation in this article. The first few sections in the article deals with the historical background and protocol layers of Bluetooth followed by a description of the Bluetooth parameters, the security architecture, the pairing and authentication mechanisms, the device trust levels and the service security levels. Security in Bluetooth protocol is only at the device link level with no "higher-level" end-to-end security designed, which may be implemented at the Application level. Bluetooth supports WAP as one of the Adopted Protocols and is used when connecting to a local LAN access point for communications through the Internet. Although Bluetooth and IrDA provide complimentary implementations for data exchange, having both installed in a machine will provide the best short-range wireless solution.
