Supersingular elliptic nkhaus isogeny cryptoography

Yog ib tug siv elliptic nkhaus taw tes compression tus yuam sij pej xeem yuav tsum tsis pub ntau tshaj 8x768 los yog 6144 ntsis ntev. Qhov no ua rau tus naj npawb ntawm cov khoom xa tawm roughly sib npaug rau cov tsis- quantum ruaj ntseg RSA thiab Diffie-Hellman ntawm tib theem kev ruaj ntseg classical.

Ntawm no, puas yog elliptic nkhaus cryptography ruaj ntseg?

Tsis muaj pov thawj tias elliptic nkhaus yog tiag " ruaj ntseg ". Tab sis tib yam siv rau tag nrho lwm yam crypto txiaj algorithms, yog li peb yuav tsum ua nrog qhov zoo tshaj plaws tom ntej: vim peb tsis tuaj yeem ua pov thawj tias ib qho twg nkhaus yog " ruaj ntseg ", peb yuav siv nkhaus tias peb tsis paub yuav ua li cas tawg (thiab tsis yog vim tsis muaj kev sim).

Tsis tas li ntawd, Quantum kev ruaj ntseg cryptography yog dab tsi? Quantum - kev nyab xeeb crypto txiaj hais txog kev siv zog los txheeb xyuas cov algorithms uas tiv thaiv kev tawm tsam los ntawm ob qho tib si classical thiab quantum computers, khaws cov ntaub ntawv muaj nqis ruaj ntseg txawm tias tom qab loj-scale quantum computer tau tsim.

Raws li, quantum computers puas tuaj yeem rhuav tshem cryptography?

Loj universal quantum computers tuaj yeem tawg ob peb nrov public-key cryptoography (PKC) systems, xws li RSA thiab Diffie-Hellman, tab sis qhov ntawd yuav tsis kawg encryption thiab kev ceev ntiag tug raws li peb paub. Nyob rau hauv thawj qhov chaw, nws yog tsis zoo li hais tias loj-scale quantum computers yuav yuav tsim nyob rau hauv ob peb xyoos tom ntej no.

Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm elliptic nkhaus cryptography tshaj elgamal?

Elliptic Curve Cryptography tau ua ib qhov chaw tshawb fawb tsis ntev los no hauv thaj teb ntawm Cryptography . Nws muab qib siab dua ntawm kev ruaj ntseg nrog tsawg dua qhov tseem ceeb piv rau lwm yam Cryptographic cov txheej txheem. Daim ntawv no muab cov ntsiab lus ntawm ellipticcurves thiab lawv siv hauv cryptoography.
