Dab tsi yog asymmetric key encryption thiab nws ua haujlwm li cas?

• Asymmetric key encryption yog ib txoj hauv kev encryption uas siv ob peb tus yuam sij sib txawv: ib tug pej xeem key thiab tus yuam sij ntiag tug.
• Tus yuam sij rau pej xeem tau sib koom qhib thiab siv los encrypt cov ntaub ntawv, thaum tus yuam sij ntiag tug khaws cia zais cia thiab siv los decrypt lawv.
• Txoj kev asymmetric key encryption ua haujlwm yog nyob ntawm kev ua lej nyuaj ntawm kev tsim thiab cuam tshuam rau ob tus yuam sij: Nws yog ib qho yooj yim rau encrypt nrog pej xeem tus yuam sij, tab sis yuav luag tsis yooj yim sua kom decrypt yam tsis muaj tus yuam sij ntiag tug.
• Txoj kev no muab kev ruaj ntseg siab hauv kev sib txuas lus digital: Cov ntaub ntawv encrypted nrog pej xeem tus yuam sij tuaj yeem tsuas yog decrypted los ntawm tus neeg txais,⁤ uas tuav tus yuam sij ntiag tug.
• Asymmetric key encryption feem ntau yog siv rau hauv computer kev ruaj ntseg systems, xws li kev ruaj ntseg pauv cov ntaub ntawv nyob rau hauv Internet los yog cov digital kos npe ntawm cov ntaub ntawv hluav taws xob.
