A method for bus addressing includes receiving handshaking information from a component of a control system of an unmanned aerial vehicle (UAV), allocating a communication address to the component through a field bus, receiving a user instruction indicative of an index number of the component through a configuration interface, and establishing a correlation between a physical address of the component, the communication address, and the index number. The index number is configured to identify the component.

The present application relates to an apparatus and method of authenticating and verifying a message frame on a multi-master access bus with message broadcasting. Logic bus identifier, LID, are associated with each one of a several logical groups of nodes out of a plurality of nodes connected to the multi-master access bus. A key is assigned to each logical group. The keys assigned to different logical groups differ from each other. For message authentication, a logic bus identifier, LID is provided and a key associated with the logic bus identifier, LID, is retrieved. A cryptographic hash value, MAC, is generated using the retrieved key and based on at least the logic bus identifier, LID. A message frame is composed, which comprises the logic bus identifier, LID, and the cryptographic hash value, MAC. For message verification, a message frame is received, which comprises at least a logic bus identifier, LID, and a cryptographic hash value, MAC. A key is retrieved, which is associated with the logic bus identifier, LID, extracted from the frame. A cryptographic verification hash value, VAC, is generated using the retrieved key and based on at least the logic bus identifier, LID. The cryptographic verification hash value, VAC, and the cryptographic hash value, MAC, extracted from the frame are compared. The received message frame is forward for further processing as a legitimate message frame.

In order to perform message routing utilizing service-oriented communication without having inquiry of a routing database storing all message transmission paths between a plurality of controllers, a message routing system according to an embodiment includes: an adapter configured to perform a conversion between a CAN message for CAN (Controller Area Network) communication and a service message for service-oriented communication; and a gateway configured to receive an offer-service message and a service subscription message from the plurality of controllers through the adapter, and set a message transmission path between the plurality of controllers based on the offer-service message and the service subscription message.

Embodiments of Vehicle-to-everything (V2X) communications authentication are described. In some embodiments, a user equipment (UE) configured V2X communication and configured to operate within a fifth-generation system (5GS) and/or a combined 5GS and fourth-generation system (4GS) can encode a V2X capability indication in a request message for transmission to a network entity, such as a Access and Mobility Management Function (AMF). The V2X capability indication can indicate a capability of the UE for V2X communication over a PC5 reference point, and the request message can further include an indication of a Radio Access Technology (RAT). In some embodiments, the AMF can determine whether the UE is authorized to use the V2X communications over the PC5 reference point, and whether the UE is authorized to use the RAT indicated in the request message. Accordingly, the AMF can transmit a V2X services authorization to a next generation radio access network (NG-RAN).

A timestamp unit and a communication control unit for a user station. The timestamp unit includes a memory, which cyclically stores a timestamp of a message, which is transmitted via a communication network, an address counter, which is incrementable with each storing of a timestamp of a message, so that the value of the address counter corresponds to an address at which the timestamp is stored in the memory, a first interface to a host control unit via which the timestamp of a message is capturable, and a second interface to a communication control unit, which creates or reads at least one message for/from the user station, the interface including a connection for receiving a trigger signal from the communication control unit, which prompts the capturing of a timestamp, and a connection for transmitting a signal to the communication control unit, which includes the value of the address counter.

A method for detecting anomalies in a controller area network of a vehicle and an apparatus for the same. The method for detecting anomalies in a Controller Area Network (CAN) of a vehicle includes monitoring the controller area network of the vehicle and generating sequence trees for respective multiple sub-networks included in the controller area network at a time at which monitoring is performed, comparing at least one normal sequence tree, generated in accordance with the controller area network when a status of the vehicle is normal, with the generated sequence trees, and calculating differences between traffic proportions for respective nodes based on a result of the comparison between the sequence trees, and detecting an anomaly in the vehicle in consideration of the differences.

A method of using a controlled interface for managing data communicated between a first device and a second device. The method includes storing a first low-level protocol address and a second low-level protocol address in the controlled interface, receiving from the first device a first signal at a first part of the controlled interface, the first signal having first high-level addressing data, stripping the high-level addressing data to yield a first payload, associating the low-level protocol address with the first payload, transmitting the low-level addressed payload to a second part of the controlled interface, stripping, at the second part of the controlled interface, the low-level protocol address associated with the low-level addressed payload, associating a second high-level addressing data to the payload and transmitting the high-level addressed payload from the second part of the controlled interface to the second device.

Provided is an in-vehicle gateway device which is capable of performing efficient path selection control when data is transferred to a different network. In an in-vehicle gateway device that performs transfer control of data between a first network and a second network, the second network has a different network form from the first network, and a virtual IP address is allocated to the second network.
