摘要： A method is disclosed for operating a motor vehicle having a computing device providing computing power, a communication device for communicating with a vehicle-external cloud provided with a server device, and a control device, wherein the control device performs an availability check indicating the existence of free computing power available from the motor vehicle for executing a computing task provided by a currently-reachable cloud as determined by the motor vehicle's communication device. From within a list of currently-reachable clouds, a target cloud to which the motor vehicle's computing power must be provided is selected either manually by user input or at least partially automatically based on availability parameters. Once a target cloud is selected, a communication link with the target cloud is established and the motor vehicle is logged into the target cloud as a provider of computing power. A motor vehicle for performing the method is also disclosed.

摘要： 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. The security unit produces a trusted execution environment, of the authentication arrangement with a hardware-encoded key information, on the basis of which the user data are encrypted by the encryption/decryption device.

摘要： The present disclosure relates to a control device for redundant execution of an operating function, wherein the control device comprises at least a first processor unit and a second processor unit and a plurality of peripheral units and a first switching unit is provided for the first processor unit and a second switching unit is provided for the second processor unit, and wherein the control device is designed in a first operating mode to execute the operating function by means of the first processor unit and in the meantime to execute a predetermined auxiliary function by means of the second processor unit. According to the invention, the control device is designed, in a second operating mode to execute the operating function by means of the second processor unit, and in so doing to continue to execute the auxiliary function (24) in a predefined reduced scope by means of the second processor unit, wherein a coupling device is provided, which is designed to connect the second processor unit to the first switching unit.
