2.5.5. Security Model
If Automotive device implementations support multiple users, they:
[
9.5
/A-1-1] MUST include a guest account that allows all functions provided by the
vehicle system without requiring a user to log in.
If Automotive device implementations support a secure lock screen, they:
[
9.9
.2/A-1-1] MUST support encryption per user-specific authentication keys.
File-Based
Encryption (FBE)
is one way to do it.
Automotive device implementations:
[
9.14
/A-0-1] MUST gatekeep messages from Android framework vehicle subsystems,
e.g., whitelisting permitted message types and message sources.
[
9.14
/A-0-2] MUST watchdog against denial of service attacks from the Android
framework or third-party apps. This guards against malicious software flooding the
vehicle network with traffic, which may lead to malfunctioning vehicle subsystems.
2.6. Tablet Requirements
An
Android Tablet device
refers to an Android device implementation that is typically used by holding
in both hands and not in a clamshell form-factor.
Android device implementations are classified as a Tablet if they meet all the following criteria:
Have a power source that provides mobility, such as a battery.
Have a physical diagonal screen size in the range of 7 to 18 inches.
Tablet device implementations have similar requirements to handheld device implementations. The
exceptions are in indicated by an * in that section and noted for reference in this section.
2.4.1. Hardware
Screen Size
[
7.1
.1.1/Tab-0-1] MUST have a screen in the range of 7 to 18 inches.
Minimum Memory and Storage (Section 7.6.1)
The screen densities listed for small/normal screens in the handheld requirements are not applicable
to tablets.
USB peripheral mode (Section 7.7.1)
If tablet device implementations include a USB port supporting peripheral mode, they:
[
7.7.1
/Tab] MAY implement the Android Open Accessory (AOA) API.
Virtual Reality Mode (Section 7.9.1)
Virtual Reality High Performance (Section 7.9.2)
Virtual reality requirements are not applicable to tablets.
