Elliptic-curve cryptography yog ib txoj hauv kev rau pej xeem-qhov tseem ceeb cryptography raws li cov qauv algebraic ntawm elliptic nkhaus hla thaj tsam kawg. ECC tso cai rau cov yuam sij me dua piv rau cov tsis yog EC cryptography los muab kev ruaj ntseg sib npaug.
Dab tsi yog elliptic nkhaus cryptography siv rau?
Elliptic nkhaus cryptography tam sim no tau siv ntau yam kev siv: tsoomfwv Meskas siv nws tiv thaiv kev sib txuas lus sab hauv, Tor project siv nws los pab kom tsis qhia npe, nws yog mechanism siv los ua pov thawj cov tswv cuab ntawm bitcoins, nws muab kos npe rau hauv Apple's iMessage kev pabcuam, nws yog siv los encrypt DNS …
txhais li cas los ntawm elliptic nkhaus?
Nyob rau hauv kev ua lej, ib qho elliptic nkhaus yog ib tug du, projective, algebraic nkhaus ntawm genus ib tug , nyob rau hauv uas muaj ib tug taw tes O. Ib tug elliptic nkhaus yog txhais nyob rau hauv ib daim teb. K thiab piav qhia cov ntsiab lus hauv K2, Cartesian khoom ntawm K nrog nws tus kheej.
Yuav ua li cas lub elliptic nkhaus ua haujlwm?
Elliptic nkhaus cryptography (ECC) yog cov txheej txheem tseem ceeb rau pej xeem encryption raws li txoj kev xav ntawm elliptic nkhaus uas tuaj yeem siv los tsim kom nrawm dua, me dua, thiab ua tau zoo dua cov yuam sij cryptographic. … Cov thev naus laus zis tuaj yeem siv ua ke nrog rau feem ntau pej xeem txoj kev encryption tseem ceeb, xws li RSA thiab Diffie-Hellman.
Puas yog elliptic nkhaus cryptography symmetric lossis asymmetric?
ECC yog txoj hauv kev - txheej txheej txheej txheem rau tiam 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.
