Ib pawg ntawm cov kws tshawb fawb Suav pom ib txoj hauv kev los ua txhaum tus qauv algorithm Rivest-Shamir-Adleman 2048 ntsis (RSA-2048) siv hauv blockchains, suav nrog kev lag luam xws li cov ntaub ntawv khaws cia, tuam txhab nyiaj thiab ntau dua.
Txhawm rau ua kom muaj ntau cov ntaub ntawv encryption raws tu qauv, pej xeem key cryptography (PKC) cov qauv, xws li RSA. Nws yog tus yuam sij rau pej xeem siv los encrypt tus yuam sij tsim cov ntaub ntawv, kom ntseeg tau tias nws tuaj yeem khaws cia rau hauv qhov nruab nrab tawm, raws li ntau lub teb chaws tech loj heev IBM lub vev xaib.
Raws li lub Kaum Ob Hlis 2016, US National Institute of Standards and Technology (NIST) tau tshaj tawm tsab ntawv thov rau kev xaiv tsa los tsom mus rau kev txhim kho pej xeem-key quantum-safe cryptographic algorithms. IBM tau tsim ob lub ntsiab algorithms nyob rau hauv Lub Xya hli ntuj 2022, uas yog CRYSTALS-Kyber (tseem ceeb tsim) thiab CRYSTALS-Dilithium (digital kos npe), tej zaum yuav siv nyob rau hauv feem ntau, lub tuam txhab hais tias.
Quantum khoos phis tawj tuaj yeem ncav cuag qhov kev ua kom zoo, uas yuav tuaj yeem rhuav tshem ntau tus yuam sij encryption niaj hnub no hauv ob peb feeb. Kwv yees 18 quadrillion cov khoom yuav tsum tsim kom muaj quantum computer ntawm 54 qubits. 100 qubits yuav nqos cov khoom ntau dua li atoms hauv ntiaj teb. Thiab lub tshuab 280 qubit yuav xaus nrog tag nrho cov atoms hauv lub ntiaj teb paub. "Hnub no cov txheej txheem tsis zoo cryptographic tuaj yeem yog keeb kwm sai sai," said International Monetary Fund (IMF) hauv 2021.
Raws li kev tshaj tawm xov xwm, Japanese tech giants Fujitsu thiab Riken tshawb fawb lub koom haum xav tias yuav nthuav qhia lub peev xwm Bitcoin-beating quantum computer sai sai hauv 2023. Cov ntawv ceeb toom qhia tias nws yuav tawm hauv lub ntiaj teb ceev tshaj plaws supercomputer Frontier tsim los ntawm Hewlett-Packard, siv nyob rau hauv cov cheeb tsam ntawm nyiaj txiag forecasting thiab tshuaj teb.
"Quantum suav muaj peev xwm hloov lub ntiaj teb ntawm qib loj. Koj tuaj yeem daws teeb meem hauv molecular dynamics, nyiaj txiag, "saib Fujitsu CEO Vivek Mahajan hauv kev xam phaj nrog CNBC thaum Lub Kaum Hli 14, 2022.
Raws li cov xov xwm tshaj tawm, lub tuam txhab thev naus laus zis Google tau lees tias tau ua tiav 'quantum supremacy' los ntawm nws cov Sycamore quantum nti hauv 2019. Nws tau xav tias nws yuav ua pov thawj zoo rau kev tsim kho thev naus laus zis. Bit qhov no tau ntes lub qhov muag ntawm cov qub tub rog hauv qhov tsis paub meej rau yav tom ntej ntawm cryptocurrency thiab Bitcoin.
"Zoo li qhov tshwm sim yog lwm tus txiv leej tub uas yav dhau los tshaj tawm tias nws muaj peev xwm ua txhaum kev cai asymmetric encryption siv cov khoos phis tawj classic ... tab sis cov neeg tshuaj xyuas pom qhov tsis zoo hauv nws cov txheej txheem thiab tus txiv neej ntawd yuav tsum thim nws daim ntawv. Tab sis pab neeg Suav no pom tau tias cov kauj ruam uas tua tag nrho cov khoom tuaj yeem daws tau los ntawm cov khoos phis tawj me me quantum. Yog li lawv tau sim thiab nws ua haujlwm, "tus kws tshaj lij Kev Ruaj Ntseg Roger Grimes hais.
Ethereum (ETH) co-founder Vitalik Buterin tau pom tias tsis muaj teeb meem los ntawm Google lub quantum supremacy nyob rau hauv kev sib raug zoo rau qhov muaj peev xwm hem ntawm crypto. Tsis tas li ntawd, BTC thiab ETH yog tsim los ntawm kev siv cryptographic algorithms uas lub tuam txhab quantum tshuab tau yooj yim outdate nws, raws li YahooFinance.
Nancy J. Allen yog tus nyiam crypto thiab ntseeg tias cryptocurrencies txhawb tib neeg los ua lawv tus kheej lub tsev txhab nyiaj thiab nqis ib sab ntawm kev sib pauv nyiaj ib txwm muaj. Nws kuj tseem nyiam los ntawm blockchain thev naus laus zis thiab nws txoj haujlwm.
