\"Studim:<\/p>\n

Filip Markert nga Instituti i Siguris\u00eb IT t\u00eb Horst G\u00f6tz, Universiteti i Ruhrit Bochum dhe Maximilian Golla nga Instituti i Siguris\u00eb dhe Privat\u00ebsis\u00eb Max Planck zbuluan se n\u00eb praktik\u00eb psikologjia dominon mbi matematik\u00ebn. Nga pik\u00ebpamja matematikore, besueshm\u00ebria e PIN-eve me gjasht\u00eb cifra \u00ebsht\u00eb duksh\u00ebm m\u00eb e lart\u00eb se ajo e PIN-eve me kat\u00ebr cifra. Por p\u00ebrdoruesit preferojn\u00eb komitime t\u00eb caktuara numrash, k\u00ebshtu q\u00eb disa PIN-e p\u00ebrdoren m\u00eb shpesh dhe kjo pothuajse e fshin diferenc\u00ebn n\u00eb kompleksitetin midis kodit me gjasht\u00eb dhe kat\u00ebr cifra.<\/p>\n

N\u00eb studim, pjes\u00ebmarr\u00ebsit e eksperimenteve p\u00ebrdor\u00ebn pajisje Apple ose Android dhe vendos\u00ebn PIN-e me kat\u00ebr ose gjasht\u00eb cifra. N\u00eb pajisjet Apple nga versioni iOS 9 u shfaq nj\u00eb list\u00eb e zez\u00eb e komprimeve numerike t\u00eb ndaluara p\u00ebr PIN-et, zgjedhja e t\u00eb cilave \u00ebsht\u00eb automatikisht e ndaluar. Hulumtuesit kishin n\u00eb dispozicion si t\u00eb dy listat e zeza (p\u00ebr kodet me 6 dhe 4 cifra) ashtu edhe ishin duke e provuar t\u00eb thyenin komprimet n\u00eb kompjuter. Lista e zez\u00eb e siguruar nga Apple p\u00ebr PIN-et me 4 cifra p\u00ebrmbante 274 numra, nd\u00ebrsa p\u00ebr kodet me 6 cifra \u2015 2910.<\/p>\n

P\u00ebr pajisjet Apple, p\u00ebrdoruesit kan\u00eb 10 p\u00ebrpjekje p\u00ebr t\u00eb futur PIN-in. Sipas hulumtuesve, n\u00eb k\u00ebt\u00eb rast lista e zez\u00eb praktikisht nuk ka asnj\u00eb kuptim. Pas 10 p\u00ebrpjekjeve, u duk se ishte e v\u00ebshtir\u00eb t\u00eb gjejm\u00eb numrin e sakt\u00eb, madje edhe n\u00ebse \u00ebsht\u00eb shum\u00eb i thjesht\u00eb (si 123456). P\u00ebr pajisjet Android, pas 11 or\u00ebsh, \u00ebsht\u00eb e mundur t\u00eb b\u00ebsh 100 fusha t\u00eb PIN-it, dhe n\u00eb k\u00ebt\u00eb rast lista e zez\u00eb tashm\u00eb \u00ebsht\u00eb nj\u00eb mjet m\u00eb t\u00eb besuesh\u00ebm p\u00ebr t\u00eb parandaluar p\u00ebrdoruesin t\u00eb fus\u00eb nj\u00eb kombinim t\u00eb thjesht\u00eb dhe p\u00ebr t\u00eb parandaluar thyerjen e smartphone-it p\u00ebrmes grumbullimit t\u00eb numrave.<\/p>\n

N\u00eb eksperiment, 1220 pjes\u00ebmarr\u00ebsit zgjodh\u00ebn vet\u00eb PIN kodet e tyre, nd\u00ebrsa eksperimentuesit p\u00ebrpiqeshin t'i gjejn\u00eb ato n\u00eb 10, 30 ose 100 p\u00ebrpjekje. Kombinimet u provuan n\u00eb dy m\u00ebnyra. N\u00ebse aktivizohej lista e zez\u00eb, telefonat inteligjent\u00eb u sulmuan pa p\u00ebrdorur numrat nga lista. Pa aktivizimin e list\u00ebs s\u00eb zez\u00eb, gjetja e kodit fillonte me numrat nga lista e zez\u00eb (si m\u00eb t\u00eb p\u00ebrdorur). Gjat\u00eb experimentit doli se nj\u00eb PIN kod 4-shifror i zgjedhur me mend \u00ebsht\u00eb mjaft i sigurt dhe madje pak m\u00eb i besuesh\u00ebm se nj\u00eb kod 6-shifror.<\/p>\n

Kombinimet m\u00eb t\u00eb zakonshme 4-shifrore ishin 1234, 0000, 1111, 5555 dhe 2580 (kjo \u00ebsht\u00eb nj\u00eb kolone vertikale n\u00eb tastier\u00ebn numerike). Nj\u00eb analiz\u00eb m\u00eb e thelluar tregoi se lista ideale e zez\u00eb p\u00ebr PIN kodet 4-shifrore duhet t\u00eb p\u00ebrmbaj\u00eb rreth 1000 artikuj dhe t\u00eb jet\u00eb paksa e ndryshme nga ajo q\u00eb u p\u00ebrpilua p\u00ebr pajisjet Apple.<\/p>\n

\"Studim:<\/p>\n

N\u00eb fund, studiuesit zbuluan se PIN kodet 4-shifrore dhe 6-shifrore jan\u00eb m\u00eb pak t\u00eb sigurta se fjal\u00ebkalimet, por m\u00eb t\u00eb besuesh\u00ebm se bllokimi grafik i telefonave inteligjent\u00eb (sip\u00ebrfaqet).
