A device obtains proof of its authority to use a first set of selectively activated features (first proof). An authorization server signs the first proof with its private key. The device sends a request to use a network service to a network node. The device sends the first proof to the network node. The network node validates the first proof using a public key of the authorization server. The network node grants the request to use the network service. The device sends a request for proof of authority for the network node to provide the network service (second proof). The device obtains the second proof, signed by another authorization server, and validates the second proof before using the network service. The first proof and the second proof each include a list of selectively activated features, where the selectively activated features are needed to use or provide the network service.

Validating authorization for use of a set of features of a device

One or more selectively activated features needed at a device to use a network service may be identified. Authorization information and feature activation key(s) associated with features that the device has been authorized to activate may be obtained at the device. The feature activation key(s) may be used to activate and/or maintain activation of the authorized features that match the selectively activated feature(s) needed to use the network service. An authorization server may obtain a request to activate one or more selectively activated features of a device. The authorization server may verify that the selectively activated feature(s) are authorized to be used at the device based on an authorization agreement obtained at the authorization server. The authorization server may send proof that the device is authorized to use the selectively activated feature(s) and may send feature activation key(s) based on the authorization agreement in response to the request.

Subsystem for authorization and activation of features

One or more selectively activated features needed at a device to use a network service may be identified. Authorization information and feature activation key(s) associated with features that the device has been authorized to activate may be obtained at the device. The feature activation key(s) may be used to activate and/or maintain activation of the authorized features that match the selectively activated feature(s) needed to use the network service. An authorization server may obtain a request to activate one or more selectively activated features of a device. The authorization server may verify that the selectively activated feature(s) are authorized to be used at the device based on an authorization agreement obtained at the authorization server. The authorization server may send proof that the device is authorized to use e selectively activated feature(s) and may send feature activation key(s) based on the authorization agreement in response to the request.
