1. A method for transmitting data among components of a system electronics of a mobile system, comprising:
- encrypting the data to be transmitted by a transmitting component in real time, wherein the data to be transmitted includes one of a signature and an identifier of the transmitting component;
decrypting the data by a receiving component in real time;
examining the transmitted data for authenticity on the basis of at least one of a) an encryption algorithm and b) the one of the signature and the identifier; and
if the examination of authenticity of the transmitted data turns out to be negative, using suitable replacement data in place of the transmitted data.
