A process for protected data transfer between a mobile ID transmitter and a control device in a motor vehicle includes establishing wireless communication between an ID transmitter and the control device, wherein a connection is established using a spread spectrum process with first connection parameters and establishing encrypted data communication on this communication connection. Second connection parameters are generated in the mobile ID transmitter or the control device, and the second connection parameters are transmitted via the encrypted data communication of the wireless communication connection. Subsequently, the communication connection is changed to use of the second connection parameters of the spread spectrum process in the ID transmitter or the control device to create a modified communication connection, and the data communication is continued via the modified communication connection.
