  • Publication number: 20220006822
    Abstract: An approach for monitoring a data transmission system that uses a data transmission means such as a vehicle bus or a vehicle network of a motor vehicle. This system includes a monitoring device that transmits a request message to a transmitting device and to a receiving device. The transmitting device generates a particular transmitter response on the basis of the request message, where the transmitter response is transmitted to the monitoring device. The receiving device generates a particular receiver response on the basis of the request message, where the receiver response is transmitted to the monitoring device. The monitoring device receives the transmitter response and the receiver response and checks compliance with a trigger condition which depends on the transmitter response and the receiver response, the compliance of which indicates an event relevant to monitoring.

  • Patent number: 11212118
    Abstract: The application relates to a method for checking the data transport across a first communication connection between two data processing devices, said first communication connection being realized between two first interface units, wherein the payload to be transferred can be divided into payload blocks and there is at least one second communication connection between the data processing devices, which is established by means of second interface units, and wherein, in order to implement a challenge-response authentication, a request requiring retrieval of randomly selected data units from identifiable, randomly selected payload blocks of the payload is sent as a challenge by an authentication unit to the first interface units by means of the second communication connection, an authentication assembly of each of the first interface units extracts the requested response data from the payload and transmits the same back to the authentication unit and a successful check is determined if the response data match.

  • Patent number: 10949552
    Abstract: An apparatus includes an authentication arrangement for a communication connection, using a communication protocol, between two data processing devices of the apparatus. The data processing devices each have an interface unit for the communication connection and a computation unit. The interface units each have an encryption/decryption device, where the encryption/decryption device is at least partially produced by hardware for encrypting at least some of the user data to be transmitted via the communication connection as part of the authentication arrangement. The encryption/decryption device can be applied in a communication layer of the communication protocol to the user data prepared for the physical user data transmission or to the physically received user data. Each data processing device has a security unit, implemented as dedicated hardware that the computation unit cannot access and/or in a manner logically isolated from the computation unit.

  • Publication number: 20210073424
    Abstract: An approach for operating at least one touch-sensitive, flat input device of a complete device, the input device being connected via a message-based bus connection to a control device of the complete device, and messages containing touch datasets describing touch data events being transmitted to the control device, which evaluates the messages for input information for an application program implemented by the control device, wherein when a security function in the control device that queries sensitive input information is accessed, the touch datasets are transmitted from the input device to the control apparatus via the bus connection in encrypted form until the associated input process has ended.

  • Publication number: 20200334355
    Abstract: A data-processing device includes a computing unit and an interface unit using a packet-based communication protocol, in particular PCI Express. The data-processing device also includes an intrusion detection unit that is connected via a signal connection to a filter device of the interface unit, and/or to a secure element, in the form of a Trusted Execution Environment, of an authentication arrangement related to the communication protocol. The intrusion detection unit evaluates input signals received via the signal connection for a rule infringement in a set of intrusion detection rules. The filter device, at least part of which is hardware, is designed to forward only the communication data meeting an approval condition from the interface unit to an additional component of the data-processing device according to configuration information predetermined in the data-processing device and containing the approval condition.
