The fundamental aim of the invention is to decrease the level of complexity for the actual encryption. This involves the use of more time and computing capacity for preparing the encryption. This preparation phase delivers the crucial security for transmitting digital data. As a result, the actual encryption of the plaintext remains simple and can be rapidly carried out. This results in only insignificantly increasing the amount of data. In contrast to prior art methods, the inventive method uses a number of different algorithms/functions.
