Abstract
A method for processing telegrams in an automation network provides a master subscriber to at least partially encrypt and output telegrams, respectively, to another subscriber. The other subscriber comprises an input port, a receiving logic connected to the input port, a decryption unit connected to the receiving logic, and a processing unit connected to the decryption unit and the receiving logic. The receiving logic is configured, when a telegram at least partially encrypted by the master subscriber is present at the input port, to forward an encrypted portion of the telegram to the decryption unit. The decryption unit is configured to decrypt the encrypted portion of the telegram with a key, and to forward the encrypted portion to the processing unit for processing. If an unencrypted telegram is present at the input port, the receiving logic is configured to forward the unencrypted telegram to the processing unit for processing.
