Betula HUC with Terminal Mode - A Terminal Mode implementation and evaluation

Abstract

This report deals with the concept Terminal Mode, which is a recently developed standard by Nokia and Consumer Electronics for Automotive for connecting mobile phones to displays and input devices. The concept aims to be an industry standard for integration of mobile applications with the car environment. The master thesis project will implement a Terminal Mode client and the report will deal with the different parts needed to create a Terminal Mode client. Terminal mode is capable of using different physical transport methods but in this report only USB is considered, the reason for this was that the not fully developed Terminal Mode server prototype phone provided by Nokia only supported USB. FPS measurements were made but the results were not satisfying because there was a limitation in the prototype device. The report ends with a deep analysis of the standard. The analysis main focus is on security mechanisms in the protocol but also other systems with the same purpose as Terminal Mode is analyzed and compared. The outcome of the analysis was that Terminal Mode is secure if the security mechanisms are used correctly and that Terminal Mode can become a leading standard for enabling apps in the car. The big question is if car manufacturers will trust the classification of applications made by the smartphone manufacturers and if the customers want to pay for these features.
