A method for checking a license for the usage of at least one performance property in an Internet of things device, is provided, having the steps of —ascertaining at least one license condition for the usage of the performance property of the IoT device by at least one attribute contained in a license identifier, —transmitting and storing the license identifier, —checking the license condition by a) generating a pseudo-access which is assigned to the performance property using a pseudo-holding unit and b) checking an authorization for the pseudo-access by checking the attribute of the license identifier using a verification unit, and —activating the at least one performance property if the pseudo-access is confirmed, wherein the license identifier, the pseudo-holding unit, and the verification unit are designed based on a specification for verifiable credentials.

Digital rights management is extended such that control over the access to data stored in a cloud remains with the originator of the data. The access information is coordinated between a rights application in the cloud and a rights server outside the cloud. A rights policy is used for fine-grained regulation of the access for users (user groups), computers (client, server) and validity periods. The access limits actions that can be performed with the data, such as a server application being provided with access to index said data without being able to access the complete contents of the data in the process. The access extension may be used for any type of distributed data processing in which the data are intended to be protected against unauthorized access operations.

A method for securely transmitting time-critical data within a communication system that includes local networks each having a switch and a plurality of terminals, a controller that controls functions of switches and terminals, and having a control network assigned to the controller and separate from the local networks, where communication within the local networks is implicitly authorized based on an assignment of respective terminals to the same local network, each terminal is assigned a zero trust adapter that captures status information, transfers the status information via the control network to the controller for evaluation and authenticates the terminal to the controller to communication partners, and where the controller determines a trust index for each of the terminals based on the status information and applies rules dependent on the trust index for configuration or permissible communication relationships of the terminals.

Provided is a network adapter for unidirectional transmission of a user data stream to a bidirectional network interface, the network adapter including: a first connection unit which is physically connected to a bidirectional network interface of a first device; a second connection unit which is physically connected to a bidirectional network interface of a second device; and a terminating unit which has at least one bit transmission module and which is designed to establish a bidirectional data link to the network interface of the first device, to receive the user data stream from the first device exclusively in a unidirectional fashion via the data link, and not to send a user data stream to the first device.
