SYSTEMS AND METHODS FOR ASSET TYPE FINGERPRINTING AND DATA MESSAGE DECODING
A method for by an asset tracking system is provided. An example method includes receiving a first plurality of data messages from an asset coupled to the asset tracking system and attempting to identify an asset type fingerprint based on the first plurality of messages. In response to failing to identify an asset type fingerprint based on the first plurality of messages, the example method further includes requesting a determined asset type fingerprint for the asset from an asset data analysis system, providing access to the first plurality of data messages to the asset data analysis system, receiving the determined asset type fingerprint for the asset from the asset data analysis system, and obtaining asset information from the asset by decoding a second plurality of data messages received from the asset in accordance with a set of signal definitions linked to the determined asset type fingerprint.
DATA TRANSMISSION SYSTEM
A marine-type communication device that reads data from a data bus, dynamically creates new data channels for a plurality of operational systems and performs a volatility assessment to determine when to save the data for transmission to a cloud network and when to transmit the data to the cloud network.
Using an out-of-band network to reconfigure a bus interface port
Provided are a computer program product, system, and method for using an out-of-band network to coordinate a first node reconfiguring a bus interface port used by a second node to communicate on a bus. The first node configures the bus to enable the second node to link to the bus. The second node sends a join request to the first node over an out-of-band network separate from the bus in response to determining that the second node cannot join the bus. The first node reconfigures the bus to enable the second node to communicate on the bus in response to receiving the join request from the second node over the out-of-band network.
Secure bridging of controller area network buses
A vehicle network system is disclosed. The vehicle network system includes a first controller area network (CAN) bus including a first node and a first secure transceiver and a second CAN bus including a second node and a second secure transceiver, a gateway to enable transmission of a CAN message from the first node to the second node. The vehicle network system also includes an auxiliary communication link to transmit an auxiliary data derived from the CAN message from the first secure transceiver to the second secure transceiver.
USER STATION FOR A SERIAL BUS SYSTEM, AND METHOD FOR TRANSFERRING DATA WITH MANIPULATION PROTECTION IN A SERIAL BUS SYSTEM
A user station for a serial bus system and a method for transferring data with manipulation protection in a serial bus system. The user station includes a communication control device for creating messages which are to be transmitted serially via a bus line to at least one other user station of the bus system, and/or for reading the messages which have been received serially from the bus line. The communication control device is designed to use a predetermined communication rule for creating and/or reading messages, and the communication control device, for creating and/or reading messages, is designed to use at least one rule for creating and/or reading the messages, which is different from the predetermined communication rule, when a predetermined trigger occurs.
INFORMATION PROCESSING DEVICE AND MANAGEMENT DEVICE
An information processing device which transmits and receives a message to which a communication ID indicating a class has been assigned, includes: a storage unit which stores, for each of the communication IDs, a communication counter for verifying a recency of a communication; a recency information management unit which updates the communication counter based on a predetermined condition; an abnormality monitoring unit which identifies an influence range of an abnormality that occurred; and a message generation unit which generates a synchronization request message including the communication ID indicating that it is a message requesting a synchronization of the communication counter, and a synchronization target identifier indicating the influence range identified by the abnormality monitoring unit.
DETECTION DEVICE, GATEWAY DEVICE, DETECTION METHOD, AND DETECTION PROGRAM
An abnormality in an on-vehicle network is accurately detected through a simple process. A detection device is configured to detect an abnormality in an on-vehicle network including a plurality of on-vehicle devices, and includes: a monitoring unit configured to monitor transmission messages in the on-vehicle network, and acquire a communication load in the on-vehicle network; an acquisition unit configured to acquire a history of a communication load in an on-vehicle network to which the detection device belongs, or another on-vehicle network; and a detection unit configured to detect an abnormality in the on-vehicle network, based on the history acquired by the acquisition unit and on the communication load acquired by the monitoring unit at a first timing after the history.
ENABLING GLOBAL QUALITY OF SERVICE FOR REAL-TIME SELECTION OF BEST DATA COMMUNICATIONS CHANNELS IN AUTONOMOUS DRIVING VEHICLES
An orchestrator ensures the best available vehicle communication technology is selected. In the computer architecture, the orchestrator is injected on the data bus line is also coupled to a plurality of independent silos of vehicle communication technologies for autonomous driving vehicle technologies. Real-time accurate strength signals associated with the plurality of independent silos are received. One of the independent silos of communication is selected for rerouting the data transfer, based on a type of data involved in the data transfer, and based on a best available of the plurality of independent silos for the data transfer type. The data transfer is directed over the selected independent silo that is the best available.
DETECTING ANOMALIES ON A CONTROLLER AREA NETWORK BUS
A process detects anomalies on a controller area network (CAN) bus. An arbitration field in a message on the CAN bus is analyzed, and a data field in the message on the CAN bus is inspected. The process further monitors a frequency of message identifiers that are transmitted across the CAN bus, and determines that an overall bus load crosses a threshold. The process then transmits an alert when the analyzing the arbitration field, the inspecting the data field, the monitoring the frequency, and the determining the overall bus load indicate that an anomaly has occurred on the CAN bus.
METHOD OF DETECTING MALICIOUS NODE IN BUS NETWORK SYSTEM AND NODE APPARATUS
A method of detecting a malicious node in a bus network system includes pre-storing, by a receiving node, autocorrelation characteristics and node identifiers for each signal received from nodes excluding than the receiving node in a bus network system, receiving, by the receiving node, a target signal from any one of the nodes, generating, by the receiving node, an autocorrelation characteristic of the target signal, searching for an autocorrelation characteristic, which is identical to the autocorrelation characteristic of the target signal or similar to the autocorrelation characteristic of the target signal by a reference level or more, among the autocorrelation characteristics of each of the signals stored by the receiving node, determining, by the receiving node, whether a first node identifier matching the searched autocorrelation characteristic and a second node identifier extracted from a packet transmitted to the target signal are the same.
