<p>The method involves authenticating an user by a program instance right system using user data (118) for releasing use of a program instance (106) by a user, and encrypting and signaturing data (120) by the program instance, where the data comprises the user data. The data is transmitted from the program instance to a component (104) i.e. machine controller, over a transmission channel (108), and the data is decrypted in the component. The program instance is authenticated with respect to the component, and the user is authenticated by a component right system using the user data. Independent claims are also included for the following: (1) a control device comprising a unit for transferring of data over a transmission channel (2) a component comprising a component right system (3) a computer-readable memory medium comprising instructions for executing a method for transferring of data in an automation network.</p> |
