Abstract: A method in which user information is transmitted from at least one data source to a processing unit of a learning device. The user information is used, by the processing unit via a machine learner, to generate at least one user model. The at least one user model is adapted via an adaptation of parameters used by the at least one machine learner to generating the at least one user model. The parameters, used by the at least one machine learner for generating the at least one user model, are adapted as a function of at least one predefined rule. The user model generated on the basis of the adapted parameters is used to personalize at least one terminal.

Abstract: A method is described for processing of user-specific data in a vehicle; in particular, the processing of user-specific data in control systems of a vehicle, such as a navigation system or an entertainment system, for example. For this purpose, the device for processing user-specific data is expanded by a private operating mode. In this private operating mode, there is no persistent storage of user inputs and/or the resulting processing results. After termination of the newly created private operating mode, the data stored during the private operating mode are deleted immediately.

Abstract: A method for excluding a participant from a group of multiple participants, in which certificates are used for an authorized communication of the participants among each other, a withdrawal request being received by one participant of the group, the withdrawal request making an identification of the participant to be excluded possible by the participant to be excluded itself, and the authorized communication being terminated by the participant when it is identifiable as the participant to be excluded based on the withdrawal request, as well as a communication system for carrying it out.

Abstract: For communication of a first participant with at least one additional participant in a communication system via multiple protocols, the protocols using at least two different certificate formats, the first participant uses different certificates with the respective certificate formats for the communication via the different protocols, the different certificates being based on a shared public key. The first participant holds a shared associated private key for the different certificates. Provision of the certificates for the first participant includes generating the public key and the associated private key, signing the public key for provision of the first certificate, and signing the public key for provision of the second certificate.

Abstract: A method for safeguarding a network made up of at least one first device and one second device. The first device derives a first challenge from physical properties of a first communication channel between the first device and the third device. In addition, the first device transmits the first challenge to the second device via a second communication channel between the first device and the second device. The first device receives a first response, corresponding to the first challenge, from the third device via the first communication channel and receives a second response, corresponding to the first challenge, from the second device via the second communication channel. The first device compares the first response and the second response to one another to verify that the second device is communicating with the third device.
