Hauv pej xeem tus yuam sij cryptography , ob cov yuam sij yog siv, ib tus yuam sij yog siv rau encryption thiab thaum lwm yam yog siv rau decryption. 3. Ib private key cryptography , cov tus yuam sij khaws cia ua ib qho zais cia. Hauv pej xeem tus yuam sij cryptography , ib ob cov yuam sij khaws cia ua ib qho zais cia.
Tom qab ntawd, qhov sib txawv ntawm pej xeem thiab ntiag tug keycryptography yog dab tsi?
Lub ntsiab qhov sib txawv ntawm tus yuam sij pej xeem thiab tus yuam sij ntiag tug hauv cryptoography yog tus pej xeem key yog siv rau cov ntaub ntawv encryption thaum lub tus yuam sij ntiag tug yog siv rau decryption cov ntaub ntawv. Nyob rau hauv luv luv, cov lus encrypted nrog lub pej xeem key tsis tuaj yeem decrypted yam tsis siv qhov sib xws tus yuam sij ntiag tug.
Qhov thib ob, txoj kev encryption tseem ceeb ntawm pej xeem yog dab tsi? Public - key encryption yog ib tug cryptographic system uas siv ob cov yuam sij --a pej xeem key paub sawv daws thiab a tus kheej los yog zais cia tus yuam sij paub tsuas yog tus tau txais cov lus. Piv txwv li: Thaum John xav xa lus ruaj ntseg rau Jane, nws siv Jane's pej xeem key rau encryption cov lus.
Khaws qhov no hauv kev txiav txim siab, koj txhais li cas los ntawm tus lej zais zais zais zais?
A tus yuam sij ntiag tug yog ib qho me me ntawm cov cai uas yog khub nrog pej xeem tus yuam sij teeb tawm algorithms rau cov ntawv nyeem encryption thiab decryption. Nws yog tsim los ua ib feem ntawm pej xeem qhov tseem ceeb cryptography thaum lub sij hawm asymmetrical key encryption thiab siv los decrypt thiab hloov cov lus rau ib hom ntawv nyeem tau. A tus yuam sij ntiag tug tseem hu ua a tus yuam sij zais cia.
Public keycryptography siv rau dab tsi?
A Definition ntawm Public Key Cryptography Public key cryptography siv ib khub cov yuam sij los encrypt thiab decrypt cov ntaub ntawv los tiv thaiv nws tiv thaiv tsis tau tso cai nkag los yog siv. Cov neeg siv network tau txais a pej xeem thiab tus yuam sij ntiag tug khub los ntawm cov ntaub ntawv pov thawj. Qhov no tus yuam sij yog siv rau encrypt cov lus, thiab xa mus rau tus neeg txais.
