Kev nkag mus siv feem ntau txhawm rau tiv thaiv cov ntaub ntawv hauv kev thauj mus los thiab cov ntaub ntawv ntawm so. Txhua zaus ib tug neeg siv lub ATM lossis yuav ib yam dab tsi hauv online nrog lub xov tooj smartphone, encryption yog siv los tiv thaiv cov ntaub ntawv raug xa mus.
Kev siv encryption nyob qhov twg hauv lub neej txhua hnub?
'Cryptography hauv lub neej niaj hnub' muaj ntau qhov xwm txheej uas siv cov ntaub ntawv zais cia yooj yim rau kev pabcuam kev nyab xeeb: rho nyiaj los ntawm ATM, Them TV, email thiab khaws ntaub ntawv siv zoo nkauj Tsis pub twg paub (PGP) freeware, ruaj ntseg web browsing, thiab siv GSM xov tooj ntawm tes.
Kev siv encryption yog dab tsi?
Qee yam ntawm cov txheej txheem encryption feem ntau suav nrog AES, RC4, DES, 3DES, RC5, RC6, thiab lwm yam. Tawm ntawm cov algorithms no, DES thiab AES algorithms yog qhov paub zoo tshaj plaws. Thaum peb tsis tuaj yeem npog txhua yam sib txawv ntawm kev encryption algorithms, cia peb saib peb qhov feem ntau.
piv txwv ntawm kev encryption yog dab tsi?
Kev nkag mus yog txhais raws li kev hloov pauv ntawm qee yam rau cov lej lossis cov cim kom nws cov ntsiab lus tsis tuaj yeem nkag siab yog tias cuam tshuam. Thaum xa email tsis pub leej twg paub thiab koj siv qhov kev pab cuam uas tsis pom nws cov ntsiab lus, qhov no yog qhov piv txwv ntawm kev encryption.
Qhov twg encryption siv online?
Kev nkag mus yog tus txheej txheem ntawm kev sib tsoo lossis nkag cov ntaub ntawv, thiab tsuas yog ib tus neeg uas muaj tus yuam sij tuaj yeem nyeem lossis nkag mus rau nws. Koj tuaj yeem siv nws rau tej yam xws li kev yuav khoom hauv online,siv mobile banking, lossis siv cov ntawv xa xov muaj kev ruaj ntseg.
