Bluetooth technology has enjoyed tremendous success, and it's now employed in billions of devices for short—range wireless data and real—time audio or video transfer. In this book the authors provide an overview of Bluetooth security. They examine network vulnerabilities and provide a literature fireview comparative analysis of recent security attacks. They analyze and explain related countermeasures, including one based on secure simple pairing, and they also propose a novel attack that works against all existing Bluetooth versions. They conclude with a discussion on future research directions. The book is appropriate for practitioners and researchers in information security, in particular those engaged in the design of networked and mobile devices.
