4. Izinqubo zokubethela zisebenza kanjani
I-Los amaphrothokholi wokubethela Basebenzisa ama-algorithms ezibalo ukuze baguqule idatha ibe ifomethi ebethelwe. Lawa ma-algorithms asebenzisa okhiye bokubethela kanye nokukhishwa kwemfihlo ukuze kuqinisekiswe ukuvikeleka kolwazi. Ngumamukeli ogunyaziwe kuphela onokhiye olungile wokususa ukubethela ongahlehlisa inqubo futhi afinyelele idatha yoqobo.

5. Izinzuzo zokusebenzisa izivumelwano zokubethela
Ukusetshenziswa kwe amaphrothokholi wokubethela inikeza izinzuzo ezibalulekile mayelana nokuphepha. Ngokubhala ngekhodi idatha, unciphisa ingcuphe yolwazi olubucayi olungabanjwa futhi lusetshenziswe kabi. Ukwengeza, izivumelwano zokubethela zisiza ukugcina ubumfihlo bezokuxhumana eziku-inthanethi.

6. Imikhawulo yezivumelwano zokubethela
Noma amaphrothokholi wokubethela Ziyisinyathelo sokuphepha esisebenzayo, azinaphutha. Ukuvikeleka kwamaphrothokholi okubethela kungase kufakwe engcupheni ngenxa yobuthakathaka kuma-algorithms asetshenziswa noma ngokuhlaselwa izinhlangano ezinonya. Kubalulekile ukuhlala uphezu kwezibuyekezo zokuphepha namapeshi ukuze ugcine ubuqotho bezivumelwano zokubethela.

7. Ukubaluleka kokubuyekeza okuqhubekayo
Ngoba amasu we ukubethela futhi ukususa ukubethela kuhlala kuvela, kubalulekile ukuhlala unolwazi lwakamuva ngezivumelwano zokubethela zakamuva kanye nemikhuba ehamba phambili yokuvikela. Ukuvuselela njalo amasistimu nesofthiwe esetshenziswayo kubalulekile ukuze kuqinisekiswe ukuvikelwa okusebenzayo kolwazi.

Kafushane, amaphrothokholi wokubethela Zibalulekile ukuze kuqinisekiswe ukuvikeleka kolwazi lwe-inthanethi. Lawa masethi emithetho nezinqubo asebenzisa ama-algorithms ezibalo ukuze abethele idatha futhi ayivikele kuyo ukufinyelela okungagunyaziwe. Kubalulekile ukuqonda izinhlobo ezahlukene zezivumelwano zokubethela, izinzuzo nemikhawulo yazo, futhi uhlale unolwazi lwakamuva ngezinqubo zokuphepha zakamuva ukuze ugcine ubuqotho bolwazi oluku-inthanethi.

Q&A

1. Iyini iphrothokholi yokubethela?

Iphrothokholi yokubethela Kuyiqoqo lemithetho nezinqubo ezisetshenziselwa ukufaka ikhodi kanye nokuqopha ulwazi futhi ngaleyo ndlela kuqinisekiswe ukuthi kuyimfihlo.

2. Iyini inhloso yezivumelwano zokubethela?

El Inhloso eyinhloko yamaphrothokholi wokubethela uwukuqinisekisa ukuphepha kolwazi oludluliswa ngamanethiwekhi noma olugcinwe kumadivayisi.

3. Yiziphi izinhlobo ezivame kakhulu zokubethela?

  1. Ukubethela kwe-Symmetric.
  2. Ukubethela kwe-asymmetric (noma ukhiye osesidlangalaleni).
