Abstract: Methods, systems, and computer-readable media for generating a secured hierarchical document are described herein. A hierarchical document is obtained and is processed to generate a secured hierarchical document. A security label is applied to each node in the hierarchical document. The secured hierarchical document is generated by cryptographically segregating the nodes according to the security label of each node. The secured hierarchical document comprises a plurality of encrypted layers. Each encrypted layer comprises at least a subset nodes associated with a respective security label and encrypted with a respective encryption key. The secured hierarchical document is stored to computer-readable memory. Methods, systems, and computer-readable media for searching a corpus of secured hierarchical documents indexed in an index as sensitive information by a computing entity trusted to have access to the sensitive information in the index are also described herein.

Abstract: A device configuration method for a vehicle in a fleet of vehicles comprises, at a computing device communicatively coupled to electronic devices provided in the vehicle, obtaining at least one template configuration file assigned to the computing device based on a user selection, the at least one template configuration file specific to the fleet of vehicles and comprising first configuration data indicative of a manner in which the computing device is to interface with the electronic devices, and second configuration data indicative of a desired setting for at least one configuration parameter of one or more electronic devices, automatically self-configuring for operation based on the first configuration data, and transmitting, at least in part, the second configuration data to the one or more electronic devices to cause the one or more electronic devices to adjust the at least one configuration parameter to the desired setting.
