ECC yog ib txoj hauv kev - ib txheej txheej ntawm cov algorithms rau cov cim tseem ceeb, encryption thiab decryption - ua asymmetrical cryptoography. Asymmetrical cryptographic algorithms muaj cov cuab yeej uas koj tsis siv ib tus yuam sij - xws li hauv symmetrical cryptographic algorithms xws li AES - tab sis tus khub tseem ceeb.
Tsis tas li ntawd, puas yog AES symmetric lossis asymmetric?
Yog ib yam tus yuam sij yog siv rau ob qho tib si encryption thiab decryption, cov txheej txheem tau hais tias yog symmetrical. Yog siv cov yuam sij sib txawv, cov txheej txheem txhais tau tias yog asymmetric. Ob qho ntawm feem ntau siv encryption algorithms hnub no yog AES thiab RSA.
Ib yam li ntawd, ECC puas zoo dua RSA? ECC cov Lub ntsiab kom zoo dua yog tias koj tuaj yeem siv cov yuam sij me me rau tib qib kev ruaj ntseg, tshwj xeeb tshaj yog nyob rau theem siab ntawm kev ruaj ntseg (AES-256 ~ ECC -512 ~ RSA -15424). Qhov no yog vim qhov zoo nkauj algorithms rau factoring zoo li Number Field Sieve. Qhov zoo ntawm ECC : Cov yuam sij me me, ciphertexts thiab kos npe.
Ib sab ntawm no, yog Ecdsa symmetric lossis asymmetric?
ECDSA yog ib qho kos npe algorithm muab los ntawm ECC (elliptic nkhaus cryptography). Qhov txiaj ntsig loj ntawm asymmetrical encryptions zoo li ECC yog tias tus neeg encrypting cov ntaub ntawv yuav tsum tsis paub tus yuam sij uas yog siv los decrypt.
ECC siv rau dab tsi?
Elliptical nkhaus cryptography ( ECC ) yog pej xeem cov txheej txheem encryption raws li elliptic nkhaus txoj kev xav uas tuaj yeem ua tau siv rau tsim kom nrawm dua, me dua, thiab ua tau zoo dua cov yuam sij cryptographic.

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
Kuv puas tuaj yeem siv ECC thiab tsis yog ECC nco ua ke?
Teb: ECC (Yuam Kev Kho Code) memoryis parity memory thiab non-ECC memory isnon-parity. Qee qhov chaw hais tias koj tuaj yeem sib xyaw ob hom RAM thiab ECC RAM yuav ua haujlwm asnon-ECC nco. Txawm li cas los xij, feem ntau cov tuam txhab nco tsis txhawb kev sib xyaw ob hom, yog li sim nws ntawm koj tus kheej qhov kev pheej hmoo
Puas yog BitLocker symmetric lossis asymmetric?
Yog tias nkag siab raug los ntawm cov ntawv tshaj tawm no thiab nplooj ntawv Wikipedia rau BitLocker thiab TPM, los ntawm lub neej ntawd, BitLocker siv symmetric 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 BitLocker tsis siv asymmetric encryption (piv txwv li, RSA)?
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
