Method and apparatus for providing security service for vehicle-dedicated data channel in linking between vehicle head unit and external device

摘要

A method and apparatus for providing a security service for a vehicle-dedicated data channel in linking between a vehicle head unit and an external device is disclosed. The method of providing the security service for the vehicle-dedicated data channel may include: transmitting, to the terminal, a predetermined integrity verification request message for requesting integrity verification of application software and an operating system included in the terminal; receiving an integrity verification result message from the terminal, exchanging a plaintext symmetric key with the terminal when integrity of the operating system and the application software is successfully verified according to the integrity verification result message; and establishing a vehicle-dedicated data channel to the terminal and transmitting and receiving a packet encrypted using the plaintext symmetric key through the established vehicle-dedicated data channel when the plaintext symmetric key is successfully exchanged.
