Challenges of Security and Trust of Mobile Devices as Digital Avionics Component
This addresses security risks for aviation systems when using mobile devices, but it is incremental as it reviews existing proposals and issues.
The paper tackles the integration of mobile devices into digital avionics systems, such as for Electronic Flight Bags and maintenance, by analyzing security and trust challenges and proposing guidelines to address them.
Mobile devices are becoming part of modern digital avionics. Mobile devices can be applied to a range of scenarios, from Electronic Flight Bags to maintenance platforms, in order to manage and configure flight information, configure avionics networks or perform maintenance tasks (including offloading flight logs). It can be argued that recent developments show an increased use of personal mobile devices playing an integral part in the digital avionics industry. In this paper, we look into different proposals for integrating mobile devices with various avionics networks -- either as part of the Bring Your Own Device (BYOD) or Corporate Owned Personally Enabled (COPE) paradigms. Furthermore, we will evaluate the security and trust challenges presented by these devices in their respective domains. This analysis will also include the issues related to communication between the mobile device and the aircraft network via either wired or wireless channels. Finally, the paper puts forward a set of guidelines with regards to the security and trust issues that might be crucial when enabling mobile devices to be part of aircraft networks.
