Zoo. Txawm hais tias muaj kev sib cav tseem ceeb ntawm seb puas muaj qhov rov qab rau hauv elliptic nkhaus random tooj generators, lub algorithm, raws li ib tug tag nrho, tseem muaj kev ruaj ntseg zoo. Txawm hais tias muaj ntau qhov tsis zoo hauv cov kev tawm tsam sab nraud, lawv tau yooj yim txo los ntawm ntau cov txheej txheem.
ECC puas nyab xeeb?
Ob hom tseem ceeb sib koom tib yam khoom tseem ceeb ntawm kev ua asymmetric algorithms (ib tus yuam sij rau kev nkag mus thiab ib tus yuam sij rau decrypting). Txawm li cas los xij, ECC tuaj yeem muab tib theem ntawm cryptographic zogntawm ntau qhov me me ntawm qhov tseem ceeb - muab kev ruaj ntseg zoo dua nrog cov kev xav tau txo qis.
Vim li cas elliptical nkhaus ruaj ntseg?
Qhov txiaj ntsig tseem ceeb tau cog lus los ntawm elliptic nkhaus cryptography yog tus yuam sij me me, txo qis kev cia thiab kev xa mus, piv txwv li tias pawg elliptic nkhaus tuaj yeem muab tib theem kev ruaj ntseg them los ntawm ib qho RSA-raws li system nrog ib tug loj modulus thiab correspondingly loj tus yuam sij: piv txwv li, ib tug 256-ntsis …
Puas elliptic nkhaus cryptography muaj kev nyab xeeb dua li RSA?
RSA vs ECC: Kev xaus
Elliptic Curve Cryptography (ECC) muab qib sib npaug ntawm kev nkag siab lub zog raws li RSA (Rivest-Shamir-Adleman) algorithm nrog lub ntsiab lus luv luv. Raws li qhov tshwm sim, nrawm thiab kev nyab xeeb muab los ntawm ECC daim ntawv pov thawj yog siab dua li daim ntawv pov thawj RSA rau Public Key Infrastructure (PKI).
Puas NIST nkhaus ruaj ntseg?
NISTmuaj cov txheej txheem elliptic nkhaus cryptography rau digital kos npe algorithms hauv FIPS 186 thiab rau cov phiaj xwm tseem ceeb hauv SP 800-56A. Hauv FIPS 186-4, NIST pom zoo kaum tsib elliptic nkhaus ntawm ntau qib kev ruaj ntseg rau siv hauv cov qauv elliptic nkhaus cryptographic.
