Public key encryption, los yog public key cryptography, yog ib txoj kev encrypting cov ntaub ntawv nrog ob lub yuam sij sib txawv thiab ua ib qho ntawm tus yuam sij, tus yuam sij pej xeem, muaj rau txhua tus siv. … Public key encryption tseem hu ua asymmetric encryption. Nws yog siv dav, tshwj xeeb tshaj yog rau TLS / SSL, uas ua rau HTTPS ua tau.
Public key encryption ua haujlwm li cas?
Nyob rau hauv pej xeem tus yuam sij cryptography, txhua tus yuam sij pej xeem sib tw rau tsuas yog tus yuam sij ntiag tug xwb. Ua ke, lawv tau siv los encrypt thiab decrypt cov lus. Yog tias koj encode cov lus uas siv ib tus neeg tus yuam sij rau pej xeem, lawv tsuas tuaj yeem txiav txim siab nws siv lawv tus yuam sij ntiag tug.
Dab tsi yog 6 lub ntsiab ntawm pej xeem tus lej encryption?

Puas yog public key encryption nyab xeeb?
Tus qauv pej xeem-tus yuam sij encryption muaj kev nyab xeeb tsuav yog tus neeg tawm tsam paub tsis muaj dab tsi ntxiv dua li pej xeem tus yuam sij. Tab sis cov tuam txhab nyiaj txiag thiab lwm lub koom haum loj nrhiav kev ruaj ntseg tiv thaiv kev tawm tsam ntau dua, hu ua xaiv-ciphertext attacks (CCAs), uas tus neeg tawm tsam kuj muaj cov piv txwv ntawm kev ua tiav kev decryption.
Ib qho piv txwv ntawm pej xeem key encryption yog dab tsi?
Kev tshuaj xyuas ntawm Public Key Cryptography, thiab Ib qho piv txwv tshwj xeeb: PGP. Anchor link. … Public key encryption yeej tsuas yog encrypts tus yuam sij symmetric, uas yog siv los decrypt cov lus tseeb. PGP yog ib qho piv txwv ntawm cov txheej txheem uas siv ob qho tib si symmetric cryptography thiab pej xeem tus yuam sij cryptography (asymmetric).
