A device and method for operating a communications network in a vehicle, or for operating an industrial communications network; a control entity for the communications network, in particular, a software-defined networking controller, determining a countermeasure after detection of an attack; an infrastructure component being configured as a function of the countermeasure, in particular, by setting at least one filtering, blocking or forwarding rule; and at least one data stream from or to at least one other infrastructure component being isolated by the infrastructure component, in a portion of the communications network; or at least one data stream to or from an end node being isolated by the infrastructure component, in a portion of the communications network.

Method and device for operating a communications network

A method for generating a shared key between two users of a network. The two users respectively have at least one clock as well as an arrangement for detecting a certain surroundings variable. The two users detect the certain surroundings variable synchronously at respectively predefined points in time or start a detection of a course of the surroundings variable. Finally, the two users respectively generate the shared key taking values detected in this manner for the surroundings variable into account.

Method for generating a key in a network and users configured for this purpose

A method for synchronizing two communication networks of an electronic data-processing system, each of the networks including one or more respective nodes, may include establishing for each of the networks a respective time schedule that establishes at least one respective time slot for a respective synchronization message. The synchronization message time slots are established to coincide. The synchronization message of the first communication network is generated by one of the nodes of the first communication network. The synchronization message of the second communication network is generated as a function of the synchronization message of the first communication network.

The invention refers to a method for monitoring a communication media access schedule of a communication controller () of a communication system () by means of a bus guardian (). The communication system () comprises a communication media () and nodes () connected to the communication media (). Each node () comprises a communication controller () and a bus guardian () assigned to the communication controller (). Messages are transmitted among the nodes () across the communication media () based on a cyclic time triggered communication media access scheme. In order to provide a mechanism which allows the bus guardian () to monitor the communication media access scheme of the communication controller () even during startup of the communication it is suggested, that the bus guardian () has a priori knowledge about possible deviations from the communication media access schedule during startup of the communication and that the bus guardian () during startup makes use of the a priori knowledge to distinguish between an allowed deviation and a forbidden deviation caused by a failure of the communication controller ().

A method and a bit stream decoding unit for bit stream decoding has a bit stream comprising a number of consecutive samples. In order to provide for rapid and, in particular, reliable decoding of the bit stream, a detection window comprising a number of samples is defined and the detection window is positioned at certain positions on the bit stream in order to comprise certain samples with respective sample values. A majority voting is applied to the sample values in the detection window and, in dependence on the result of the majority voting, the bit stream is decoded and respective bit values are generated.
