Abstract

Since its creation, Bluetooth has transformed itself from a cable replacement technology to a wireless technology that connects people and machines. Bluetooth has been widely adapted on mobile phones and PDAs. Many other vendors in other industries are integrating Bluetooth into their products. Although vendors are adapting to the technology, Bluetooth hasn’t been a big hit among users. Security remains a major concern. Poor implementation of the Bluetooth architecture on mobile devices leads to some high profiled Bluetooth hacks. Weak security protocol designs expose the Bluetooth system to some devastating protocol attacks. This paper first explores four Bluetooth protocol-level attacks in order to get deeper insights into the weakness of the Bluetooth security design. It then proposes enhancements to defense against those attacks. Performance comparison will be given based on the implementation of those enhancements on a software based Bluetooth simulator.
