Chikwata chevanozvipira cheGerman-America uye akaenzanisa chengetedzo yenhamba-nhanhatu uye mana-manhamba PIN kodhi yekukiya smartphone. Kana smartphone yako yakarasika kana kubiwa, zviri nani kuti uve nechokwadi chekuti ruzivo ruchadzivirirwa kubva pakubira. Ndizvo here?
Philipp Markert anobva kuHorst Goertz Institute for IT Security paRuhr University Bochum naMaximilian Golla kubva kuMax Planck Institute for Security and Privacy vakaona kuti mukuita psychology inotonga masvomhu. Kubva pamaonero emasvomhu, kuvimbika kwenhamba-nhanhatu PIN kodhi yakakwira zvakanyanya kupfuura mana-manhamba. Asi vashandisi vanosarudza mamwe masanganiswa enhamba, saka mamwe maPIN kodhi anoshandiswa kazhinji uye izvi zvinodzima mutsauko mukuoma pakati pematanhatu- uye mana-manhamba makodhi.
Muchidzidzo ichi, vatori vechikamu vakashandisa Apple kana Android zvishandiso uye kuseta mana- kana matanhatu-manhamba ePIN kodhi. Pamidziyo yeApple kutanga neIOS 9, rondedzero nhema yedhijitari inorambidzwa musanganiswa wemaPIN kodhi yakaonekwa, iyo sarudzo inorambidzwa otomatiki. Vatsvagiri vaive nemavara evatema paruoko (ye6- uye 4-manhamba-makodhi) uye vakamhanyisa kutsvaga kwekusanganiswa pakombuta. Rondedzero yakasviba ye4-manhamba PIN kodhi yakagamuchirwa kubva kuApple yaive ne274 manhamba, uye 6-manhamba - 2910.
Pamidziyo yeApple, mushandisi anopihwa gumi kuedza kuisa PIN. Maererano nevatsvakurudzi, munyaya iyi blacklist inoita kuti zvive zvisina musoro. Mushure mekuedza gumi, zvakava zvakaoma kufungidzira nhamba chaiyo, kunyangwe iri nyore kwazvo (se10). Kumidziyo yeAroid, 10 PIN kodhi yekupinda inogona kuitwa mumaawa gumi nerimwe, uye mune iyi nyaya, iyo blacklist yatove nzira yakavimbika yekuchengeta mushandisi kupinda musanganiswa wakapusa uye kudzivirira iyo smartphone kubva pakubirwa nenhamba dzechisimba.
Mukuyedza, vatori vechikamu 1220 vakasarudza vakazvimiririra maPIN kodhi, uye vanoedza vakaedza kufungidzira mugumi, makumi matatu kana zana. Kusarudzwa kwemasanganiswa kwakaitwa nenzira mbiri. Kana iyo blacklist yakagoneswa, mafoni akarwiswa pasina kushandisa nhamba kubva pane iyo rondedzero. Pasina iyo blacklist yakagoneswa, kusarudzwa kwekodhi kwakatanga nekutsvaga kuburikidza nenhamba kubva kublacklist (seanonyanya kushandiswa). Panguva yekuedza, zvakazoitika kuti PIN kodhi yakasarudzwa zvine hungwaru, nepo ichidzikamisa nhamba yekuedza kupinda, yakachengeteka uye yakatonyanya kuvimbika pane 10-manhamba PIN kodhi.
MaPIN macode ainyanyozivikanwa aive 4, 1234, 0000, 1111 uye 5555 (iyi ndiyo koramu yakatwasuka pabhaidhi renhamba). Ongororo yakadzama yakaratidza kuti iyo yakanakira blacklist yechina-manhamba PINs inofanirwa kunge iine zviuru zvekupinda uye ive yakasiyana zvishoma neiyo yakatorwa kuApple zvishandiso.
Pakupedzisira, vatsvakurudzi vakaona kuti 4-manhamba uye 6-manhamba ePIN kodhi haana kuchengeteka zvishoma kudarika mapassword, asi akachengeteka kupfuura pattern-based smartphone locks. Full ichaunzwa muSan Francisco muna Chivabvu 2020 paIEEE Symposium paChengetedzo uye Chakavanzika.
