Los ntawm Wikipedia, phau ntawv dawb encyclopedia. Elliptic-nqaj cryptography ( ECC ) yog ib txoj hauv kev rau pej xeem-qhov tseem ceeb cryptography raws li cov qauv algebraic ntawm elliptic curves hla thaj tsam kawg. ECC xav tau cov yuam sij me dua piv rau cov tsis yog EC cryptography (raws li cov chaw Galois tiaj) los muab qhov sib npaug kev ruaj ntseg.
Hauv qhov no, 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.
Tsis tas li ntawd, ECC puas ruaj ntseg? Teeb meem nrog ECC Kev siv keeb kwm tau qhia tias, txawm tias a ruaj ntseg kev siv ntawm cov ECC nkhaus yog theoretically ua tau, nws tsis yog yooj yim mus cuag. Qhov tseeb, kev siv tsis raug tuaj yeem ua rau ECC ntiag tug tseem ceeb leaks nyob rau hauv ib tug xov tooj ntawm scenarios.
Raws li txoj cai, ECC encryption ua haujlwm li cas?
Elliptic Curve Cryptography los yog ECC yog public-key cryptoography uas siv cov khoom ntawm ib qho elliptic nkhaus hla ib thaj tsam finite rau encryption . Piv txwv li, 256-ntsis ECC pej xeem tus yuam sij muab kev ruaj ntseg piv rau 3072-ntsis RSA pej xeem tus yuam sij.
Vim li cas ECC zoo dua RSA?
Elliptic nkhaus cryptography yog tej zaum zoo dua rau feem ntau lub hom phiaj, tab sis tsis yog rau txhua yam. 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). Cov yuam sij me me, ciphertexts thiab kos npe. Ceev ceev heev tiam.

Dab tsi yog kev ruaj ntseg ruaj ntseg thiab muaj nyob rau hauv kev ruaj ntseg?
Kev ceev ntiag tug txhais tau hais tias cov ntaub ntawv, cov khoom thiab cov peev txheej raug tiv thaiv los ntawm kev tsis pom zoo thiab lwm yam kev nkag. Kev ncaj ncees txhais tau tias cov ntaub ntawv raug tiv thaiv los ntawm kev hloov pauv tsis tau tso cai los xyuas kom meej tias nws ntseeg tau thiab raug. Muaj txhais tau hais tias cov neeg siv tau tso cai nkag tau rau hauv cov tshuab thiab cov peev txheej uas lawv xav tau
Lub luag haujlwm ntawm kev txawj ntse hauv kev ruaj ntseg hauv tebchaws yog dab tsi?
Lub chaw haujlwm txawj ntse yog tsoomfwv lub luag haujlwm rau kev sau, tshuaj xyuas, thiab kev siv cov ntaub ntawv hauv kev txhawb nqa kev tswj hwm kev cai lij choj, kev ruaj ntseg hauv tebchaws, tub rog, thiab lub hom phiaj ntawm txoj cai txawv tebchaws. Cov koom haum txawj ntse tuaj yeem muab cov kev pabcuam hauv qab no rau lawv cov tsoomfwv hauv tebchaws
Dab tsi yog hom kev tawm tsam hauv kev ruaj ntseg network?
Muaj ntau hom DoS thiab DDoS tawm tsam; Feem ntau yog TCP SYN dej nyab nres, teardrop nres, smurf nres, ping-of-tuag nres thiab botnets
Kev tswj hwm kev tswj hwm hauv kev ruaj ntseg ntaub ntawv yog dab tsi?
Kev tswj hwm kev nyab xeeb (tseem hu ua cov txheej txheem tswj hwm) feem ntau yog cov txheej txheem thiab cov cai uas tau muab tso rau hauv qhov chaw los txheeb xyuas thiab qhia cov neeg ua haujlwm hauv kev cuam tshuam nrog cov koom haum cov ntaub ntawv rhiab
Dab tsi yog qhov tsis qhia npe hauv kev ruaj ntseg network?
Lub network tsis qhia npe tso cai rau cov neeg siv nkag mus rau lub vev xaib thaum thaiv kev taug qab lossis taug qab lawv tus kheej hauv Is Taws Nem. Cov tes hauj lwm tsis qhia npe tiv thaiv kev tsom xam tsheb thiab kev soj ntsuam hauv network - lossis tsawg kawg ua rau nws nyuaj dua
