DATA FRAME FOR PROTECTED DATA TRANSMISSIONS

摘要

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.

1. A method for generating a data frame which contains a user data block and a code block, comprising:
generating the user data block, the user data block comprising a message, generating the code block comprising calculating a first code word by coding a first data record by means of a first coding algorithm, transforming the message into a transformed message by using the first code word, calculating a second code word using the first code word, the transformed message, and a second coding algorithm, wherein the data frame comprises the second code word but not the first code word.
