Oni su, potom, koristili informacije za generisanje tajnog klju\u010da koji je dio programa za \u0161ifrovanje, zasnovan na matematici teorije haosa, po kojoj male promjene u po\u010detnim uslovima dovode do veoma razli\u010ditih ishoda, prenosi portal zika.rs.<\/p>\n<p>Kao dokaz koncepta, njihov sistem trenutno uzima jedno EKG \u010ditanje iz dlana svakog korisnika, a klju\u010d na osnovu tog \u010ditanja se skladi\u0161ti i koristi za sva kasnija de\u0161ifrovanja.<\/p>\n<p>Lin ka\u017ee da je njihov cilj izgradnja sistema na principu eksternih hard diskova i drugih ure\u0111aja koji mogu da se de\u0161ifruju i \u0161ifruju jednostavno, prilikom dodira.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Imate problem da se sjetite koja vam je lozinka?
