Whole apparatus having an authentication arrangement, and method for authentication

Abstract

Whole apparatus (1) having an authentication arrangement for a communication connection (4), using a communication protocol, between two data processing devices (2) of the whole apparatus (1), whereinthe data processing devices (2) each have an interface unit (5) for the communication connection (4) and a computation unit (3), wherein the interface units (5) each have an encryption / decryption means (8), at least partially produced by hardware, for encrypting at least some of the user data (14) to be transmitted via the communication connection (4) as part of the authentication arrangement, said encryption / decryption means being applied in a communication layer of the communication protocol to the user data (14) prepared for the physical user data transmission or to the physically receiveduser data (14), wherein each data processing device (2) has a security unit (9), implemented as dedicated hardware that the computation unit (3) cannot access and / or in a manner logically isolated from the computation unit, and producing a trusted execution environment, of the authentication arrangement with in each case at least one piece of hardware-encoded key information (10), on the basis ofwhich the user data (14) are encrypted by the encryption / decryption means (8).

Description

technical field [0001] The invention relates to an overall device with a verification module for a communication connection using a communication protocol between two data processing devices of the overall device, wherein the data processing devices each have an interface for the communication connection Units and computing units, especially CPUs and / or GPUs and / or FPGAs and / or ASICs. Furthermore, the invention relates to a method for authentication. Background technique [0002] Modern total installations with data processing systems, such as motor vehicles, are becoming more and more complex due to the need to fulfill multiple purposes and / or programmatic advances in data processing. For example, if a motor vehicle is designed to operate completely automatically, that is to say autonomously, a data processing system with high computing power is required in order to be able to reliably process the environment of the motor vehicle and to carry out reliable driving planning....

AI Technical Summary

Problems solved by technology

This in turn means that an unauthenticated data processing device, such as a controller, can access the communication link and can present its own user data, which may not meet the requirements for the quality and / or safety of the vehicle, thereby compromising Accepted and / or added "endpoints" may also imply security issues for the rest of the data processing system
