A review of Bluetooth security in the automotive environment

The paper outlines the security issues automotive designers must consider when integrating Bluetooth into existing in-vehicle networks like CAN, TTCAN, and MOST. It also proposes possible solutions to secure the sensitive information within an in-vehicle network, allowing Bluetooth to be a securely integrated wireless automotive technology of the future. Bluetooth has become the de-facto standard for wireless short-range communication within the PDA and mobile phone sector. Automotive designers have begun implementing audio gateways as factory fitted components within today's top-of-the-range cars. Several security issues within Bluetooth have been highlighted recently within the mobile phone sector and automotive designers must protect the in-vehicle networks from both identified and possible future security risks.
