He then checks whether the content counter B has a predetermined limit value, for example exceeds 3, step 130. Is that the If so, the microprocessor 13 determines one in accordance with step 136 new random number 18 and new target response signals 16a, 16b, 16c with which he the corresponding memory contents in memory 14 overwrites. Then it breaks the mapping check process off, step 138.
  • step 130 If the check in step 130 reveals that the one assigned to counter B. Limit has not yet been exceeded, the Microprocessor 13 also redetermines the random number 18 and the target response signals 16a, 16b, 16c according to Step 136 through.
