Abstract: A method for detecting the possibility of an intrusion into a bus system. The bus system includes a plurality of components which are able to transmit messages in the bus system. The method includes ascertaining a number of messages that are transmitted by a first component of the plurality of components in a specific time period; determining whether the number of messages in the specific time period satisfies a predefined first criterion; and detecting the possibility of an intrusion if the number of messages does not satisfy the predefined first criterion.

Abstract: A computer-implemented method for intercepting an intrusion into a bus system. The method includes detecting, by way of an intrusion detection system, a frame sent by a further node of the bus system on a bus of the bus system as an intrusion into the bus system; sending data on a receive line of a node device in order to manipulate a signal, which corresponds to the frame arriving over the bus, on the receive line, the receive line being arranged between a transceiver and a controller of the node device. A node device and a bus system for intercepting an intrusion into the bus system, are also described.

Abstract: A method for checking a message in a communication system, in which multiple users are connected to a communication medium and exchange messages via same. A time difference between points in time of reception of a message that is sent on the communication medium is ascertained at two different, predefined positions on the communication medium, and based on a comparison of the time to at least one reference time difference, it is determined whether the message originates from a verified user.
