摘要
A method for automatically generating and storing of in each case an application specific secret combination (g) associated auxiliary quantities as a function of a main pass word (mpw) and the respective secret combination (g), so that the corresponding secret combination (g) with the aid of the skin password (mpw) from the this secret combination (g) associated auxiliary quantities can also be reconstructed, wherein the method with a correspondingly programmed in the following steps carried out at the device comprises:– Calculating a pseudo-random signal sequence (edge) as a function of the input main pass word (mpw),– Extraction of data blocks of certain length (k) of the pseudo-random signal sequence (edge), wherein the data blocks by means of a coding of an alphabet (a), from which the secret combination (g) is formed, in each case a character (x) from this alphabet (a) are associated with,– Comparing the extracted data blocks with characters (gi) from the secret combination (g) taking account of this coding,– Determining a block position (bpi) in each case one of the data blocks for each character (gi) from the secret combination (g), through which the coding..
