Abstract: A computer system includes a processor, a communications subsystem, and a non-transitory computer-readable storage medium. The computer-readable medium stores instructions that when executed by the processor adapt the computer system to receive an indication of a second device selected, at a first device, for update; send an indication signalling the second device to send state information about the second device; receive state information about the second device; determine, based on the state information, that the second device is ready to perform an update; send, to the first device, an indication that the second device is ready to perform the update; receive, from the first device, an indication to update the second device; and, send a corresponding indication to the second device. The second device is configured to begin updating in response to such an indication without any direct interaction with it. Related methods and computer-readable media are also described.

Abstract: Systems, methods, and software can be used to provide inter-vehicle data communications for drafting operations. In some aspects, a method is disclosed comprising: selecting, by a hardware processor of a first vehicle, a second vehicle as a candidate for a drafting group; receiving, from the second vehicle, a drafting capability indication; in response to receiving the drafting capability indication, transmitting, from the first vehicle to the second vehicle, a drafting request; receiving, from the second vehicle, a drafting response; determining, by the hardware processor of the first vehicle, to establish the drafting group including the first vehicle and the second vehicle; and transmitting, from the first vehicle to the second vehicle, a drafting confirmation, wherein the drafting confirmation indicates that the first vehicle agrees to establish the drafting group with the second vehicle.

Abstract: Systems, methods, and software can be used to provide secure inter-vehicle data communications. In some aspects, a method, comprising: receiving, at a security server and from a hardware security processor connected to a system bus of a vehicle, security confidence data of the vehicle, wherein the security confidence data include at least one of version information of a software code executing on a component of the vehicle, diagnostic data information of the vehicle, or data traffic pattern information of the vehicle; determining, at the security server, a security confidence score of the vehicle; receiving, at the security server, a query from a different vehicle; and in response to the query, transmitting the confidence score of the vehicle to the different vehicle.

Abstract: A method is provided for use on an electronic device having a display, a communication component, a memory, and a processor coupled to the display, the communication component, and the memory. The memory stores data in a first sandbox and data in a second sandbox, the first sandbox being a secure sandbox and having a shadow data component, the shadow data component storing a subset of the data stored in the first sandbox. The method comprises, in response to a request, providing the data stored in the first sandbox when the first sandbox is in an unlocked mode and providing the data stored in the shadow data component when the first sandbox is in a locked mode.
