A method for transmitting encoded traffic messages via a data channel, which is reserved for transmitting encrypted traffic messages, a certain subset of traffic messages being in general transmitted via the data channel in unencrypted form. For the encryption of the traffic messages, in each case only one of at least two components of the traffic message being encrypted. The unencrypted component containing information, or information is assigned to the unencrypted component as to whether the first component of the traffic message is encrypted, traffic message transmitter and receiver. Particularly important traffic messages may be transmitted via encrypted channels in a manner that also allows receivers that are not designed to decrypt encrypted messages to output these traffic messages or to process them further in other ways. |
