1. A network node module within a vehicle, comprising:
- a vehicle network interface configured to couple to a vehicular communication network including at least one network fabric to support communication between devices within the vehicle; and
a processing module configured to;
detect connection of a new device to the vehicular communication network, the new device configured to perform at least one task;
assign a restricted use network address to the new device that enables the new device to communicate setup information via the vehicular communication network for setup of the new device;
authenticate the new device;
upon successful authentication of the new device, replace the restricted use network address with a new network address upon authentication of the new device, wherein the new network address differs from the restricted use network address, and wherein the new network address enables the new device to communicate over the at least one network fabric of the vehicular communication network for purposes of performing the at least one task;
determine expected consumption information relating to the new device;
monitor, via the at least one network fabric, actual consumption of the new device, the actual consumption including at least one of data consumption or power consumption;
compare the actual consumption to the expected consumption information; and
when an actual consumption level deviates from the expected consumption information by more than a standard deviation, generate a service indication regarding the new device.

Abstract
A network node module within a vehicle operates to manage devices coupled to a vehicular communication network of the vehicle based on a use mode defining rights and privileges for operating in the vehicular communication network. Upon being configured in accordance with a particular use mode of a set of use modes, the network node module can identify a device coupled to the vehicular communication network and enable the device to operate within the vehicular communication network in accordance with the use mode. The network node module is securely reconfigurable to any use mode in the set of use modes.

15. A network node module within a vehicle, comprising:
-
a vehicle network interface configured to couple to a vehicular communication network including at least one network fabric to support communication between devices within the vehicle; a memory maintaining device authentication information; and
a processing module configured to;detect connection of a new device to the vehicular communication network, wherein the new device is configured to perform at least one task; assign a restricted use network address to the new device that enables the new device to communicate setup information via the vehicular communication network for setup of the new device; authenticate the new device based on the device authentication information;
replace the restricted use network address with a new network address upon authentication of the new device, wherein the new network address differs from the restricted use network address, and wherein the new network address enables the new device to communicate over the at least one network fabric of the vehicular communication network for purposes of performing the at least one task;determine expected consumption information relating to the new device;
monitor, via the at least one network fabric, actual consumption of the new device, the actual consumption including at least one of data consumption or power consumption;compare an actual consumption level to the expected consumption information to determine whether the new device is damaged; and when determining that the new device is damaged, generate a service indication; and when an actual consumption level deviates from the expected consumption information by more than a standard deviation, generate a service indication regarding the new device. - View Dependent Claims (16, 17, 18, 19)

20. A method for authenticating a new device within a vehicle, comprising:
-
detecting connection of the new device to a vehicular communication network including at least one network fabric, the new device configurable to perform at least one task; assigning a restricted use network address to the new device that enables the new device to communicate setup information via the vehicular communication network for setup of the new device; obtaining authentication information from the new device; authenticating the new device via an external network based on the authentication information; replacing the restricted use network address with a new network address upon authentication of the new device, wherein the new network address differs from the restricted use network address, and wherein the new network address enables the new device to communicate over the at least one network fabric of the vehicular communication network for purposes of performing the at least one task; determining expected consumption information relating to the new device; monitoring, via the at least one network fabric, actual consumption of the new device including at least one of data consumption or power consumption; comparing the actual consumption to the expected consumption information to determine whether an actual consumption level deviates from the expected consumption information by more than a standard deviation; and when the actual consumption level deviates from the expected consumption information by more than the standard deviation, generating a service indication regarding the new device.
