Apparatus for gateway, control method thereof and vehicle system

A method performed by a gateway device in a vehicle, the method comprising:

• executing, by a processor circuit of the gateway device, a protection algorithm to determine a Type of Service (ToS) value of a socket associated with an application of the vehicle;
• authenticating, via a secure world hosted by the gateway device and supporting a trusted execution environment, the application;
• based on a determination of whether the application is authenticated, inserting data of the application into one of:
• a security band of transmit queues of the gateway device;
• and
• a general band of the transmit queues of the gateway device;
• and
• transmitting the data of the application via the selected one of the security band and the general band.

A vehicle system for a vehicle, the vehicle system comprising:

• one or more sensors;
• a central controller controlling the vehicle;
• and
• a gateway device connected between the one or more sensors and the central controller,
• wherein the gateway device is configured to:
• execute a protection algorithm to determine a Type of Service (ToS) value of a socket associated with an application of the vehicle;
• authenticate, via a secure world supporting a trusted execution environment of the gateway device, the application;
• based on a determination of whether the application is authenticated, insert data of the application into one of:
• a security band of transmit queues of the gateway device;
• and
• a general band of the transmit queues of the gateway device;
• and
• transmit the data of the application via the selected one of the security band and the general band.
