A user station for a serial bus system and a method for transferring data with manipulation protection in a serial bus system. The user station includes a communication control device for creating messages which are to be transmitted serially via a bus line to at least one other user station of the bus system, and/or for reading the messages which have been received serially from the bus line. The communication control device is designed to use a predetermined communication rule for creating and/or reading messages, and the communication control device, for creating and/or reading messages, is designed to use at least one rule for creating and/or reading the messages, which is different from the predetermined communication rule, when a predetermined trigger occurs.
