Gulu lofufuza lodzipereka la Germany-America ndikuyerekeza chitetezo cha manambala asanu ndi limodzi ndi manambala a PIN a manambala anayi pakutseka kwa foni yamakono. Ngati foni yamakono yanu yatayika kapena yabedwa, ndibwino kuti mukhale otsimikiza kuti chidziwitsocho chidzatetezedwa kuti zisawonongeke. Ndi choncho?
Philipp Markert wochokera ku Horst Goertz Institute for IT Security ku Ruhr University Bochum ndi Maximilian Golla ochokera ku Max Planck Institute for Security and Privacy anapeza kuti muzochita zamaganizo ndizomwe zimalamulira masamu. Kuchokera pamawonekedwe a masamu, kudalirika kwa ma PIN code XNUMX ndikokwera kwambiri kuposa manambala anayi. Koma ogwiritsa ntchito amakonda kuphatikiza manambala ena, kotero ma PIN ena amagwiritsidwa ntchito nthawi zambiri ndipo izi zimangochotsa kusiyana kwazovuta pakati pa manambala asanu ndi limodzi ndi anayi.
Mu phunziroli, ophunzira adagwiritsa ntchito zida za Apple kapena Android ndikuyika ma PIN a manambala anayi kapena asanu ndi limodzi. Pazida za Apple kuyambira ndi iOS 9, mndandanda wakuda wazophatikizira zoletsedwa zama PIN zidawonekera, kusankha komwe kumaletsedwa. Ofufuzawo anali ndi mindandanda yonse yakuda (ya manambala a 6- ndi 4) ndipo adasakasaka kuphatikiza pakompyuta. Mndandanda wakuda wa manambala 4 a PIN omwe adalandira kuchokera ku Apple unali ndi manambala 274, ndi manambala 6 - 2910.
Pazida za Apple, wogwiritsa amapatsidwa kuyesa 10 kuti alowe PIN. Malinga ndi ofufuza, mu nkhani iyi blacklist kupanga pafupifupi n'zosamveka. Pambuyo poyesera 10, zinali zovuta kulingalira nambala yolondola, ngakhale ndi yosavuta (monga 123456). Pazida za Android, zolemba za PIN 11 zitha kupangidwa m'maola a 100, ndipo pakadali pano, mndandanda wakuda ndi njira yodalirika yoletsa wogwiritsa ntchito kulowa kuphatikiza kosavuta ndikuletsa foni yam'manja kuti isabedwe ndi manambala amphamvu.
Pakuyesaku, otenga nawo gawo 1220 adasankha okha ma PIN code, ndipo oyesera adayesa kuwayerekeza mu 10, 30 kapena 100 kuyesa. Kusankhidwa kwa kuphatikiza kunkachitika m'njira ziwiri. Ngati mndandanda wakuda udayatsidwa, mafoni adawukiridwa popanda kugwiritsa ntchito manambala kuchokera pamndandanda. Popanda mndandanda wakuda wothandizidwa, kusankha ma code kudayamba ndikufufuza manambala kuchokera pamndandanda wakuda (monga omwe amagwiritsidwa ntchito pafupipafupi). Pakuyesa, zidapezeka kuti PIN code yosankhidwa mwanzeru ya manambala 4, ndikuchepetsa kuchuluka kwa zoyeserera, ndiyotetezeka komanso yodalirika kwambiri kuposa nambala ya PIN ya manambala 6.
Manambala a PIN odziwika kwambiri okhala ndi manambala 4 anali 1234, 0000, 1111, 5555 ndi 2580 (iyi ndi gawo loyima pamakiyidi a manambala). Kuwunika kozama kunawonetsa kuti mndandanda wakuda wa ma PIN okhala ndi manambala anayi uyenera kukhala ndi zolemba pafupifupi 1000 ndipo ukhale wosiyana pang'ono ndi womwe udachokera ku zida za Apple.
Pomaliza, ofufuzawo adapeza kuti ma PIN okhala ndi manambala 4 ndi manambala 6 ndi otetezeka kwambiri kuposa mapasiwedi, koma otetezeka kwambiri kuposa maloko a foni yam'manja. Zodzaza idzaperekedwa ku San Francisco mu Meyi 2020 ku IEEE Symposium on Security and Privacy.
