  • Patent number: 11916924
    Abstract: Aspects of the present disclosure address systems, methods, and devices for enabling secure communication between electronic control units (ECUs) in a vehicle. The system may include a first and second ECU from a plurality of ECUs in the vehicle. The first ECU is to enable secure communication between the plurality of ECUs by performing operations that include provisioning the second ECU with authentication data for authenticating messages exchanged with a third ECU and provisioning the third ECU with a set of security keys to enable the third ECU to securely exchange messages with the second ECU. The second ECU receives, from the third ECU, a secure message that is cryptographically signed using a security key from the set of security keys provisioned to the third ECU, and the second ECU authenticates the secure message by comparing the authentication data with an authentication signal.

  • Publication number: 20230362430
    Abstract: Techniques and systems are provided for processing user interface content. For example, a server computer can receive a user interface event corresponding to a user interface of a device (e.g., a client device, another server computer, or other device). An application associated with the user interface event can be determined, and an interface model can be generated using the application associated with the user interface event. The interface model defines state information for one or more graphic objects of the user interface. The state information results from the user interface event. The server computer can send the interface model to the device, which enables the device to render the user interface.

  • Patent number: 11733061
    Abstract: A method for managing communications within a network comprising utility meters, each associated and connected to at least one utility management center through at least one intermediate data concentrator. A message is sent by a utility meter to the destination data concentrator. This message includes metering data measurement reported by said utility meter, its utility meter identifier, the destination data concentrator identifier and the management center identifier. Then, on the basis of several metering data measurements, a metering counter differential consumption value is calculated by difference of two metering counter consumption indexes measured by the utility meter within a time period interval. Then, a report containing at least the metering counter differential consumption value is sent from the destination data concentrator towards the utility management center to which said utility meter is associated.

  • Patent number: 11710971
    Abstract: A method is disclosed for controlling the operating of a consumption appliance by way of a selector switch controlled by an energy saving device connected to a management center. The consumption appliance is kept in its default power mode, until receiving, by the energy saving device, an authentic secured control message sent by the management center. This message includes a command onto the mode in which the consumption appliance has to be switched. A counter is initialized with an initialization value before to be triggered. The consumption appliance is switched in the mode indicated by the command, either until the counter has reached a threshold value, or until receiving another authentic control message. If the counter has reached the threshold value, then the consumption appliance is switched in its default power mode. If another authentic secured control message has been received, then returning to the step of initializing the counter.
