Node for a cyber-physical system and authentication method

摘要

The node comprises: a data interface for receiving data from a further node via a data network; an extraction device for extracting authentication data from the data from the further node; anda multi-level authentication level, which is designed for an authentication of the further node using the authentication data of the further node; wherein the multi-level authentication device has a first pre-authentication level, which for a first pre-authentication of the further node using at least one electronic identifier contained in the authentication data of the further node The multi-level authentication level has a second pre-authentication level which is designed for a second pre-authentication of the further node on the basis of one or more first data records contained in the authentication data of the further node, each of the first data records describing a physical characteristic of the environment of the further node ; andwherein the multi-level authentication level is designed such that the authentication of the further node takes place if both the first pre-authentication and the second pre-authentication are successful.
