Encryption of a clear text into a cipher text for securing of a motor vehicle, in particular against theft

摘要

It is a method for encrypting a clear text (20) into a cipher text (30), comprising the steps of: generating a configuration parameters (50) as a function of an encryption key (10) and random data and / or a random key (40), inputting of the clear text (20) and of the configuration parameter (50) as input data into an implementation of a cryptography algorithm (70), execution of the implementation of the encryption algorithm (70), and outputting of the secret text (30) as output data of the implementation of the encryption algorithm (70), wherein the configuration parameters (50) the program sequence of the implementation of the encryption algorithm (70) influenced.
