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.

Puas yog iPhone X screen nkhaus?
Apple lub vijtsam muab qhov tseeb 'wow' lub sijhawm thaum koj saib nws. Qhov screen yog nyob txhua qhov chaw. Nws zoo li tej yam yees siv. Cov npoo ntawm lub iPhone X lub vijtsam yog puag ncig uas lawv zoo li kev tshawb fawb tsis tseeb thaum xub thawj siab ib muag, thiab nkhaus txiav rau lub koob yees duab saum toj kawg nkaus tsuas yog txhim kho cov txiaj ntsig
Puas yog cryptography zoo ib yam li encryption?
Cryptography yog txoj kev kawm txog cov ntsiab lus zoo li Encryption, decryption, siv los muab kev sib txuas lus ruaj ntseg thaum encryption yog tus txheej txheem ntawm encoding cov lus nrog ib qho algorithm
Puas yog nkhaus keyboards zoo dua?
Nyob rau hauv lub sij hawm ntev, ntaus ntawv ntawm ib tug ergonomic keyboard zoo nkaus li zoo, koj txhais tes log tsawg dua, thiab koj muaj peev xwm txawm ntaus ntawv sai thiab ntau yog. Ntxiv rau, koj yuav txo qis kev raug mob rov ua dua (RSI) qhov twg koj tuaj yeem ua rau cov leeg nqaij, leeg, thiab cov hlab ntsha los ntawm kev ntaus ntawv
Puas muaj qhov nkhaus ntawm kev xeem AP?
Lub Tsev Kawm Ntawv Qib Siab Cov Kev Xeem AP tau muab qhab nia rau ntawm qhov nkhaus, uas muaj ntau cov qhab nia raug muab rau txhua qib, xws li 5 txog 1 (piv rau A-rau-F system). Kev muab qhab nia ntawm qhov nkhaus ua kom cov qhab nia sib npaug; Nws tsis yooj yim sua kom txhua tus tau txais ib qib
Dab tsi yog kev siv cov cuab yeej nkhaus?
Cov cuab yeej Curves yog cov cuab yeej ntse tshaj plaws rau kev hloov xim, ci ntsa iab, qhov sib piv lossis pob tshab ntawm cov txheej txheem nquag lossis xaiv. Thaum lub cuab yeej Theem tso cai rau koj ua haujlwm ntawm Duab Ntxoo thiab Cov Ntsiab Lus, Curves cov cuab yeej tso cai rau koj ua haujlwm ntawm txhua lub suab nrov
