Zusammenfassung:	The invention relates to a method for secure data transfer in an automation network (100). The method involves authenticating (S1) an user by a program instance right system using user data for releasing use of a program instance by a user, and encrypting (S2) 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 over a transmission channel (108; 202), and the data is decrypted (S4) in the component. The program instance is authenticated (S5) with respect to the component, and the user is authenticated (S6) by a component right system using the user data.
