Yog tias nkag siab raug los ntawm cov ntawv no thiab nplooj ntawv Wikipedia rau BitLocker thiab TPM, los ntawm lub neej ntawd, BitLocker siv symmetrical cryptography zoo li AES. Txawm li cas los xij, TPM muaj peev xwm ua tau RSA encryption. Muab hais tias tus yuam sij RSA khaws cia hauv TPM, vim li cas ua BitLocker tsis siv asymmetrical encryption (piv txwv li, RSA)?
Ib yam li ntawd, qhov txawv ntawm qhov sib txawv thiab asymmetrical encryption yog dab tsi?
Qhov sib txawv ntawm Symmetric thiab Asymmetric Encryption Symmetric encryption siv ib tus yuam sij uas yuav tsum tau muab qhia rau cov neeg uas xav tau txais cov lus thaum asymmetrical encryption siv ib khub ntawm tus yuam sij pej xeem thiab tus yuam sij ntiag tug rau encryption thiab decrypt cov lus thaum sib txuas lus.
Ib sab saum toj, dab tsi yog qhov sib txawv thiab asymmetric ciphers? Symmetrical thiab Asymmetric ciphers . Hauv ib symmetrical cipher , ob tog yuav tsum siv tib tus yuam sij rau encryption thiab decryption. Qhov no txhais tau hais tias tus yuam sij encryption yuav tsum tau sib koom ntawm ob tog ua ntej cov lus tuaj yeem decrypted. Hauv ib asymmetric cipher , tus yuam sij encryption thiab tus yuam sij decryption yog cais.
Kuj paub yog, puas yog asymmetric lossis symmetric encryption zoo dua?
Feem ntau asymmetric encryption schemes muaj kev nyab xeeb dua vim lawv xav tau ob qho tib si pej xeem thiab tus yuam sij ntiag tug. Tsis yog. AES muaj kev nyab xeeb dua rau kev tawm tsam cryptanalytic dua li 512-ntsis RSA, txawm tias RSA yog asymmetrical thiab AES yog symmetrical.
Qhov twg peb tuaj yeem siv cov yuam sij symmetric thiab asymmetric?
Koj tsuas xav tau asymmetrical cryptoography thaum koj xav tau rau pauv cov ntaub ntawv nrog ib tus neeg tshwj xeeb uas koj tsis muaj ib tus yuam sij pauv nrog (thiab txawm tias tom qab ntawd, koj siv symmetrical thiab encrypt tus yuam sij asymmetrically nquag) los yog thaum koj xav tau rau kos npe rau ib yam dab tsi (hauv qhov xwm txheej twg koj encryption tus hash tus nqi asymmetrically).

Vim li cas symmetric encryption sai dua asymmetric encryption?
Rau cov txheej txheem encrypt / decrypt lub luag haujlwm, symmetrical algorithms feem ntau ua tau sai dua li lawv cov asymmetrical counterparts. Qhov no yog vim lub fact tias asymmetric cryptography yog loj heev inefficient. Symmetric cryptography yog tsim los rau kev ua haujlwm zoo ntawm cov ntaub ntawv loj
Puas yog operating system yog hardware lossis software?
Lub operating system (OS) yog qhov system software uas tswj hwm lub khoos phis tawj kho vajtse, software peev txheej, thiab muab cov kev pabcuam zoo rau cov khoos phis tawj. Qhov tseem ceeb ntawm lub desktop operating system yog Microsoft Windows nrog kev ua lag luam ntawm ib ncig ntawm 82.74%
Puas yog ECC symmetric lossis asymmetric?
ECC yog ib txoj hauv kev - cov txheej txheem ntawm cov txheej txheem rau cov cim tseem ceeb, encryption thiab decryption - ua asymmetric cryptography. Asymmetric cryptographic algorithms muaj cov cuab yeej uas koj tsis siv ib tus yuam sij - xws li hauv symmetric cryptographic algorithms xws li AES - tab sis tus khub tseem ceeb
Vim li cas lo lus symmetric siv nyob rau hauv symmetric key encryption?
Symmetric Encryption yog ob-txoj kev algorithm, vim hais tias tus lej algorithm yog thim rov qab thaum lub sij hawm decryption ntawm cov lus los ntawm tib tus yuam sij zais cia. Symmetric encryption, tseem nrov hu ua private-key encryption & secure-key encryption
Dab tsi asymmetric encryption algorithm yog siv rau symmetric key pauv?
Qhov feem ntau siv symmetrical algorithm yog AES-128, AES-192, thiab AES-256. Lub ntsiab tsis zoo ntawm tus yuam sij symmetric encryption yog tias txhua tus neeg koom nrog yuav tsum tau pauv tus yuam sij siv los encrypt cov ntaub ntawv ua ntej lawv tuaj yeem decrypt nws
