A vrea sa trimita un pachet lui B. Prin posta. Si pune ce are de trimis intr-un pachet/cutie/lada/geamantan/servieta care are cifru. El stie care e propriul sau cifru, prietenul lui nu (si n-au telefoane, deci nu pot comunica decat prin posta). In postas n-au incredere. Cum fac cei doi ca sa poata prietenul B sa deschida coletul.
Solutia 1: NU TOTI POSTASII SUNT HOTI! Asa ca merg la concurenta!
Solutia 2: daca postasul e periculos pentru curiozitatea manifestat fata de ce este in pachet, atunci astia doi fac schimb de chei ..si isi trimit apoi bine mersi pachete.
(Ca sa ne inchipuim mai degraba de ce e postasul 'hot ", sa zicem ca e in timpul razboiului si ceea ce vor cei doi tipi sa transmita are valoare de secret de razboi)
Deci, A trimite pachetul cu cifrul lui pus (sau cu incuietoarea lui pua). B cand il primeste pune si el cifrul/incuietoarea lui si restituie pachetul lui A. Acesta cand il primeste deschide propriul sau cifru/incuietoare lasand inchis cifrul lui B si returneaza pachetul. B il primeste si isi deschide propriul cifru/icuietoare si gata.
