 Vreti sa trimiteti unei persoane un obiect valoros intr-o cutie.  Aveti la dispozitie cutii de tipul celei din imagine care se pot incuia cu mai multe lacate. Problema este ca trimitand separat cheia/cheile intr-un mod nesecurizat, acestea pot fi interceptate/copiate si folosite pentru a deschide cutia/cutiile.  Cum procedati, totusi, ca obiectul sa ajunga la destinatar in deplina siguranta  ?
