Data frame for protected data transmissions

A method for generating a data frame is disclosed which contains a user data block with the message and a code block. To generate the code block, a first data record is initially coded by means of a first coding algorithm in order to calculate a first code word. Subsequently, the message is transfor...

Zusammenfassung:	A method for generating a data frame is disclosed which contains a user data block with the message and a code block. To generate the code block, a first data record is initially coded by means of a first coding algorithm in order to calculate a first code word. Subsequently, the message is transformed. By using the first code words thus generated and the transformed message, a second code word is subsequently calculated by using a second coding algorithm. The data frame comprises the second code word but not the first code word.
