1. A method for securely supplying data to be used in parameterizing a device for an industrial automation system, the method comprising:
a first party supplying a second party with a machine-readable standardized container for the exchange of device parameters in industrial automation systems, wherein the supplying comprises writing into the container an encrypted primary security credential to be used by the device for establishing trust with the industrial automation system, wherein the machine-readable standardized container supplied by the first party or obtained by the second party comprises further device parameters for parameterizing the device, wherein parameterizing the device comprises extracting, by the device, the encrypted primary security credential and decrypting the encrypted primary security credential, wherein the machine-readable standardized container comprises configuration data including functional data for parametrizing the device, the machine-readable standardized container comprising a device configuration sub model and an encrypted security sub model, wherein the configuration data is stored in the device configuration sub model that is integrated in the machine-readable standardized container, the primary security credential being integrated into the encrypted security sub model.
