Most vehicles are now produced with infotainment features. However, as reported in various security conferences, security vulnerabilities associated with an infotainment system can cause serious security issues, e.g., an attacker can control in-vehicle systems through the infotainment system. To address such security issues, in this paper, we propose a session key establishment protocol using Elliptic Curve Cryptography. The proposed protocol enables secure authentication and key distribution between a user device and a telematics control unit. We also shows how a trusted execution environment is used for the proposed protocol. We present detailed protocol operations with conducted security analysis results.
