A method is provided for storing at least one domain name system container image, wherein the domain name system container image is configured to create at least one domain name system container instance in a domain name system infrastructure. The method includes: creating at least one item of signed domain name system information, wherein the at least one item of signed domain name system information is created by a cryptographic signature of an item of domain name system information, wherein the cryptographic signature is created outside the domain name system server infrastructure; creating at least one domain name system container image, wherein the at least one domain name system container image has the signed domain name system information and at least one item of domain name system server software; and storing the at least one domain name system container image in a container registry.

A computer apparatus for transmitting a certificate to a device in an installation is provided. The computer apparatus has a coupling unit for establishing and breaking a connection between the computer apparatus and the device, a processing unit for transmitting a certificate to the device by means of the established connection, wherein the certificate is valid for a first time period and is issued by a certification authority based on a certificate request, and a receiving unit for receiving a further certificate request from the device by means of the established connection, wherein the further certificate request is designed to request a certificate for a second time period, wherein the coupling unit is designed to break the connection after the certificate is transmitted and the further certificate request is received.

A system for providing a control program code (SPC) for controlling a device connected to a control device has: an authentication service which, after successful authentication of the device with respect to the authentication service, transmits a device ID (FG-ID) of the authenticated device to a commissioning service which, on the basis of the device ID (FG-ID) of the authenticated device, transmits a control program code (SPC) to a control device which controls the authenticated device using the control program code (SPC).

System and method for providing a control program code

A method, a first device, and a switching center are described. A first device is authenticated by a switching center inside a network taking into account the use of additional (e.g., virtual) network interfaces. A device uses certificates to transfer additional MAC addresses for authentication. As a result, a device having a plurality of MAC addresses gains access to a network from a plurality of MAC addresses in a one-off authentication process.

Authentication of a first device by a switching center

A network device and a method for operating a network device for an automation network are provided. The network device is set up with the help of a real-time application for providing a function of the network device. The real-time application has at least one predefined, updatable parameter. The network device has a storage device for storing update data for the updatable parameter in an update storage area and storing application data for the real-time application in an application storage area. The network device is set up such that, after update data has been written into the update storage area at a predefined update time, a first memory address referring to the application storage area switches to a second memory address referring to the update storage area in which the update data is stored. The switch takes place deterministically within a predefined update timeslot during runtime of the real-time application.

Network device and method for operating a network device for an automation network

A method for producing a hardware device, in particular a trusted platform module for the execution of at least one cryptographic algorithm, the hardware device corresponding to a real-time class, i.e., it fulfils specifiable run-time requirements for real-time applications, wherein the method comprises preparing at least one cryptographic algorithm in the manner of a program code; determining a maximum/longest execution time (WCET) for the algorithm, producing a tamper-proof hardware module, which is configured to execute the algorithm, and assigning the hardware module to a real-time class depending on the maximum/longest execution time (WCET).

Method for producing a hardware device and hardware device

A private key and a public key are provided during manufacture of a device and are stored in the device. At least one cryptographic key is subsequently negotiated, the negotiation being security-protected as a function of the generated private key and/or the public key. This method can find application in building automation.
