Jediny sposob ako tuto dilemu vyriesit, je dosiahnut riesenie, ktore je "dokonale" bezpecne a teda jeho zverejnenie neznizuje jeho ucinnost. Podobne ako sifrovacie algoritmy. Date ruku do ohna za to, ze tam nie je chyba? Myslim, ze toho kto polozil otazku netreba hned drsne karhat. V jeho situacii neexistuje "dobre" riesenie.
