Token - kuyini?

Udaba sokuphepha electronic - omunye wemizila ebaluleke kakhulu emhlabeni namuhla. Kwahlongozwa izindlela eziningi izixazululo zayo ezahlukene. Token - lena omunye wabo. Kuyini, futhi iziphi izici kwesicelo yayo khona?

Token - kuyini?

Ekuqaleni, Sichaza ezinye amagama. Token yidivayisi compact okuhloselwe ukuqinisekisa ukuphepha ulwazi umsebenzisi. Isetshenziselwa ukuhlonza kumnikazi kungenzeka yokunikeza evikelekile ukungena kokukude zonke izinhlobo kungenzeka kolwazi.

Amathokheni ingasetshenziswa esikhundleni ngephasiwedi, noma ngaphezu nalokho. ngokuvamile baba usayizi amancane kufanelekile lula isikhwama noma ephaketheni. Izinguqulo Ngini eziphambili futhi unikele ikhono ukugcina okhiye cryptographic (Isiginesha yedijithali, idatha yebhayomethrikhi). Token - kubukeka? Aziyona zonke okufanayo? Ziyahlukahluka kuye ngokubukeka, hhayi kuphela e ukusebenza: abanye babe kuphela kwesikrini, kulekelelwa nezinye ikhibhodi ezincanyana kanye nabanye nje encane inkinobho-kwalokho. Amathokheni anemisila RFID ukusebenza, USB isixhumi ne-Bluetooth esibonakalayo ukudlulisa ukhiye ohlelweni iklayenti. Yabo ukhiqiza eziningi izinkampani, futhi okunezinhlobonhlobo ebanzi. Phakathi abakhiqizi eziholela babe amabhizinisi ezifana "E Token" futhi "RuToken"

izinhlobo amathokheni

Amathokheni ayatholakala nge ezihlukahlukene ukusebenza, kuze kube sezingeni lokuba banayo izindlela ukuqinisekiswa amaningi. Laba bameleli be-elula akufanele njalo exhunywe kwi-computer. Bona ukukhiqiza inombolo, futhi umsebenzisi nje ungena kubo beyimiqemane. Kukhona amathokheni ezisebenzisa ubuchwepheshe obungenawaya be ezifana Bluetooth. Zenza ngokudlulisela ukulandelana kwezinkomba. A esikhethekile kuhlala amadivayisi zenziwa ngendlela idivayisi ye-USB. Zidinga uxhumano ngqo kwikhompyutha lapho yokufuna idatha oyokwenziwa.

Okuxubile kanye yokusabela wokusebenza ku izinhlobo ezahlukene amathokheni okuqinisekisa. Ngokwesibonelo, abanye bangase nje ukufunda ukhiye futhi enze edingekayo imisebenzi cryptographic. Abanye bangase adinga iphasiwedi ezengeziwe. izixazululo Commercial ubuchwepheshe olunikezwa izinkampani, ngokuvamile zabo izindlela zokuphepha kanye nezici ukuqaliswa. Ngakho, ithokheni USB zingenziwa ngesimo miniature flash drive, noma-ke ingaba njengesihluthulelo idivayisi yeselula zokuxhumana. Kungenzeka futhi ukuba uqaphele lapho wazifihla njengendlela Fob ukhiye noma enye into maloprimetnuyu.

ngishiyeka

Kunezinkinga ezimbili eziyinhloko nokusetshenziswa amathokheni:

1. Ukulahleka noma ukweba. Uma lezi izinqubo babe okungahleliwe ke bakhathazeke ngalutho. Kodwa uma lezi zenzo ayenziwa othile ngenhloso, kulesi simo, kuzosiza ukunciphisa izingozi ezimbili-factor lapho ukuqedela inqubo ukuhlonza akudingi nje kuphela ithokheni, kodwa iphasiwedi ukufinyelela (emile noma ngokuqhubekayo elakhiwe futhi ethunyelwe efonini yakho).
2. Icebo "indoda phakathi". Lokhu kubonakala lapho usebenza ngokusebenzisa inethiwekhi alithembekile (i-inthanethi uyisibonelo esihle). Ingqikithi yalo scheme ukuthi isiteshi uxhuma idatha cryptanalyst, ubani ongafunda futhi ukushintsha umlayezo ngokuthanda kwabo. Ngaphezu kwalokho, azikho ezazivela ongayiqondi (ngohlangothi lobuchwepheshe zezinto) ukuthi akukhona ukutshela umlingani wakhe imiyalezo.

zamaselula njengoba amathokheni

Token - kuvela engela obungajwayelekile? Ingabe kukhona izici ngokuziqhathanisa inqubo ejwayelekile? I mobile idivayisi Computing kungenzeka ezifana smartphone, noma ithebhulethi ingasetshenziswa njengendlela uphawu. Bangaphinde ukunikeza ezimbili-factor, okuyinto akudingi umuntu njalo kwenziwe inqubo ngokomzimba ngaphezulu. abakhiqizi Ingxenye ukuthuthukisa izicelo amathokheni, lapho efakwe idivayisi yeselula, futhi ukhiqize ukhiye wokubhala. Le isixazululo kuqinisekisa izinga eziphakeme zokulondeka, kufaka phakathi inkinga "indoda phakathi". Manje singasho ukuthi ulwazi oluyisisekelo mayelana uphawu - ukuthi kuyini nokuthi - obaziyo.
