    摘要： A method for forwarding data content from a second data connection and a third data connection of a node of a data network to a first data connection of the node, wherein data content received at the second data connection has priority over data content received at the third data connection, includes interrupting forwarding of data content received via the third data connection as soon as reception of data content at the second data connection is detected. The data content received at the second data connection is fed into an intermediate buffer (memory) and the output of the data content received via the second data connection, via the first data connection, is delayed for a definable time period.

    摘要： A device and method for a serial bus system. The device has a transmit signal analysis module for counting edges of a transmit signal to be transmitted on a bus of the bus system; a receive signal analysis module for counting edges of a receive signal generated from a signal transmitted on the bus because of the transmit signal; and an evaluation module for evaluating the difference that results from a comparison of the edges counted by the transmit signal analysis module and the edges counted by the receive signal analysis module. If the signal propagation time on the bus is greater than the bit time of the receive signal, the evaluation module signals whether the amount of the difference is less than or equal to a predefined value or whether the amount of the difference is greater than the predefined value, the predefined value being greater than zero.

    摘要： An overlap detection unit for a user station of a serial bus system. The overlap detection unit includes a collision detection block for detecting bus states on a bus of the bus system, in which, in order to transmit a message, bus states of user stations of the bus system are generated on the bus with a first physical layer in a first communication phase, and are generated with a second physical layer in a second communication phase, the second physical layer being different from the first physical layer. The collision detection block generates a signal whose value indicates whether or not the bus states in the second communication phase have a level that corresponds to an overlap of the first and second physical layers or an overlap of two second physical layers, and the collision detection block is designed to output the signal for the user station.

    摘要： An attack communication detection device that is robust against a deviation from the design value of a communication interval is provided. The attack communication detection device is an attack communication detection device that detects an attack communication from a communication of each electronic control unit in a communication network and includes: a receiving unit that receives communication data for detection which may or may not include an attack communication; a sum-of-communication-intervals calculation unit that calculates the sum of communication intervals, which is the sum of two adjacent communication intervals, of the communication data for detection; an estimated distribution model storage that stores in advance an estimated distribution model of a communication interval and the sum of communication intervals of communication data for learning which does not include an attack communication; and a detection unit that detects whether or not the communication data for detection includes an attack communication based on the estimated distribution model and the sum of communication intervals of the communication data for detection.
