Nws raug nquahu kom siv cov cuab yeej txheem thiab cov txheej txheem uas ua tau raws li qhov yuav tsum tau muaj kev ruaj ntseg. Tsis tas li ntawd, nws yog ib qho tseem ceeb los tsim kom muaj kev nkag mus thiab cov cai tswj xyuas qhov tseem ceeb kom ntseeg tau tias tsuas yog cov neeg tau tso cai tuaj yeem nkag mus rau cov ntaub ntawv encrypted.

10. Yuav ua li cas siv cov yuam sij muaj zog rau cov ntaub ntawv encryption

Cov ntaub ntawv encryption yog ib qho kev ntsuas tseem ceeb los tiv thaiv cov ntaub ntawv rhiab thiab ua kom nws muaj kev nyab xeeb los ntawm kev hem thawj. Ib feem tseem ceeb ntawm cov txheej txheem no yog siv cov yuam sij ruaj ntseg uas lav qhov ua tau zoo ntawm kev encryption. Nov yog qee cov kauj ruam los siv cov yuam sij muaj zog thiab ua kom muaj kev ruaj ntseg ntawm koj cov ntaub ntawv ntau tshaj plaws.

Kauj Ruam 1: Tsis txhob hnov ​​​​qab txog cov lus pom tseeb lossis pom tau

• Tsis txhob siv cov ntaub ntawv ntiag tug xws li npe lossis hnub yug.
• Tsis txhob siv cov lej lossis cov tsiaj ntawv ua ntu zus, xws li "12345" lossis "qwerty."
• Muab cov tsiaj ntawv me, tus lej loj, cov lej, thiab cov cim tshwj xeeb los tsim kom muaj qhov tseem ceeb dua.

Kauj Ruam 2: Siv cov lus zais lossis cov lus zais password

• Xaiv ib lo lus zais tshwj xeeb uas tsuas yog koj paub. Piv txwv li, thawj zaug ntawm txhua lo lus ntawm ib kab lus nco tau.
• Ntxiv cov kev hloov pauv rau cov lus hla, xws li swapping cov ntawv rau cov lej lossis cov cim tshwj xeeb.
• Piv txwv li, "kuv tus dev lub npe yog Max" tuaj yeem hloov mus rau "M1p3rRO$3l4m4M4x."

Kauj ruam 3: Siv tus password manager

• Tus neeg saib xyuas tus password tuaj yeem pab koj tsim cov yuam sij ruaj ntseg thiab khaws cia lawv encrypted.
• Ntxiv nrog rau kev siv cov yuam sij nyuaj thiab tsis sib xws, tus tswj hwm tus password kuj tso cai rau koj tswj hwm kev nyab xeeb txoj kev ntau tus yuam sij rau cov kev pabcuam sib txawv.
• Thaum xaiv tus neeg saib xyuas tus password, xyuas kom nws muaj kev ruaj ntseg zoo, xws li kev lees paub ntau yam thiab qhov kawg-rau-kawg encryption.

11. Asymmetric vs. Encryption Symmetric encryption: sib txawv thiab pom zoo siv

Asymmetric encryption thiab symmetric encryption yog ob txoj kev encryption siv nyob rau hauv cov ntaub ntawv kev ruaj ntseg, tab sis lawv txawv nyob rau hauv lawv cov hauj lwm thiab pom zoo daim ntawv thov. Symmetric encryption siv tus yuam sij tshwj xeeb rau ob qho tib si encrypt thiab decrypt cov ntaub ntawv, ua kom sai dua tab sis tsis muaj kev nyab xeeb dua piv rau asymmetric encryption. Ntawm qhov tod tes, asymmetric encryption siv ib khub ntawm cov yuam sij sib txawv, ib tus pej xeem thiab ib tus kheej, los encrypt thiab decrypt cov ntaub ntawv, muab kev ruaj ntseg ntau dua.

Qhov sib txawv tseem ceeb ntawm ob txoj hauv kev yog nyob rau hauv txoj kev ntawm cov yuam sij. Hauv symmetric encryption, ob tog koom nrog hauv kev sib txuas lus yuav tsum sib qhia tib tus yuam sij, uas tuaj yeem nthuav tawm qhov kev sib tw ntawm kev ruaj ntseg qhov tseem ceeb. Ntawm qhov tod tes, nyob rau hauv asymmetric encryption, txhua tog muaj ib tug khub ntawm cov yuam sij, ib tug pej xeem thiab ib tug private. Tus yuam sij rau pej xeem tau nthuav dav thiab siv los encrypt cov ntaub ntawv, thaum tus yuam sij ntiag tug khaws cia zais cia thiab siv los decrypt cov ntaub ntawv.

Hais txog kev pom zoo siv, symmetric encryption yog tsim nyog thaum siab encryption thiab decryption ceev yuav tsum tau, xws li nyob rau hauv kev hloov ntawm cov ntaub ntawv loj. Tsis tas li ntawd, nws muaj txiaj ntsig zoo hauv ib puag ncig uas cov yuam sij tuaj yeem tiv thaiv tau yooj yim thiab sib koom ntawm cov neeg koom nrog, xws li ntawm lub zos network ntseeg. Ntawm qhov tod tes, asymmetric encryption yog qhov zoo dua thaum kev ruaj ntseg yog qhov tseem ceeb thiab kev ruaj ntseg channel rau kev sib pauv tseem ceeb tsis tau lav. Nws yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig hauv cov ntawv thov xws li kev lees paub tus neeg siv, kos npe digital, thiab kev tiv thaiv cov ntaub ntawv rhiab heev.

2. Kev txhim kho hauv kev txawj ntse txawj ntse thiab kev kawm tshuab: Artificial txawj ntse thiab kev kawm tshuab tau ua lub luag haujlwm tseem ceeb hauv kev ruaj ntseg cov ntaub ntawv. Kev tsim kho hauv cheeb tsam no ua rau pom ntxov ntawm kev hem thawj thiab kev txheeb xyuas cov qauv tsis zoo hauv cov ntaub ntawv encrypted. Qhov no pab tiv thaiv kev tawm tsam thiab txhim kho kev ua haujlwm ntawm encryption systems.

3. Homomorphic encryption: Homomorphic encryption yog cov txheej txheem tshiab uas tso cai rau kev ua haujlwm ntawm cov ntaub ntawv encrypted yam tsis tau decrypting nws. Qhov no txhais tau hais tias cov ntaub ntawv tuaj yeem siv thiab ua tiav yam tsis muaj kev pheej hmoo ntawm kev nthuav tawm. Kev txhim kho hauv cheeb tsam no nrhiav kev txhim kho kev ua tau zoo thiab siv tau ntawm homomorphic encryption, ua kom nws siv tau ntau yam xwm txheej, los ntawm kev siv mobile mus rau huab xam.

Nyob rau hauv luv luv, lub neej yav tom ntej ntawm cov ntaub ntawv encryption yog tag nrho ntawm exciting possibilities. Kev nce qib hauv quantum encryption, kev txawj ntse txawj ntse thiab kev kawm tshuab, nrog rau homomorphic encryption, tab tom ua txoj hauv kev kom muaj kev ruaj ntseg ntau dua thiab tiv thaiv peb cov ntaub ntawv. Raws li cov kev txhim kho no txuas ntxiv mus, peb tuaj yeem cia siab tias yuav muaj kev tiv thaiv ntau ntxiv hauv lub ntiaj teb digital.

Hauv kev xaus, cov ntaub ntawv encryption yog ib qho cuab yeej tseem ceeb hauv kev tiv thaiv cov ntaub ntawv rhiab heev. Los ntawm cryptographic algorithms thiab kev siv cov yuam sij ruaj ntseg, kev tsis pub lwm tus paub thiab kev ncaj ncees ntawm peb cov ntaub ntawv yog lav.

Cov ntaub ntawv encryption tsis yog tsuas yog pom zoo rau cov koom haum thiab cov tuam txhab, tab sis kuj rau ib tus neeg siv uas xav khaws lawv cov ntaub ntawv ntiag tug kom tsis txhob muaj kev tawm tsam. Los ntawm kev siv cov txheej txheem no kom raug, kev nkag mus rau peb cov ntaub ntawv thiab cov ntaub ntawv tsis raug tso cai tuaj yeem tiv thaiv, yog li txo qhov kev pheej hmoo cuam tshuam nrog kev poob lossis tub sab ntawm cov ntaub ntawv.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev xaiv ntawm ib qho algorithm thiab kev tswj xyuas qhov tseem ceeb yog qhov tseem ceeb los lav qhov ua tau zoo ntawm cov ntaub ntawv encryption. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum muaj cov cuab yeej txhim khu kev qha thiab software uas muab peb cov qib tsim nyog ntawm kev ruaj ntseg.

Nyob rau hauv luv luv, cov ntaub ntawv encryption yog ib qho tseem ceeb xyaum nyob rau hauv kev ruaj ntseg cov ntaub ntawv. Nws txoj kev ua kom zoo ua rau peb muaj kev thaj yeeb nyab xeeb thiab kev ntseeg siab paub tias peb cov ntaub ntawv muaj kev tiv thaiv los ntawm qhov muaj peev xwm thiab kev pheej hmoo. Tsis tas li ntawd, nws tso cai rau peb ua raws li cov cai thiab cov qauv kev nyab xeeb, txawm nyob rau theem ntawm tus kheej lossis kev lag luam. Peb yuav tsum tsis txhob kwv yees qhov tseem ceeb ntawm cov txheej txheem no, vim tias nws daim ntawv thov raug yog qhov tseem ceeb ntawm kev khaws cov ntaub ntawv ntiag tug thiab kev ncaj ncees ntawm peb cov ntaub ntawv hauv ib puag ncig digitalized zuj zus.
