Bitcoin's SHA256 encryption algorithm tseem muaj kev nyab xeeb txawm tias cov kws tshawb fawb hauv Suav teb tau hais tias tawg RSA encryption nrog quantum computers uas twb muaj lawm.
Ib pawg ntawm 24 tus kws tshawb fawb Suav tau hais tias lawv tuaj yeem ua tus lej 48-ntsis siv 10-qubit quantum computer. Qhov no tuaj yeem yog qhov tseem ceeb hauv kev rhuav tshem RSA encryption algorithm uas cuam tshuam ntau ntawm kev sib txuas lus hauv internet.
Suav thov kom Optimize Shnorr Algorithm Nrog Quantum Tshuab
Cov kws tshawb fawb tau thov tias lawv tuaj yeem siv quantum computers los daws cov kauj ruam dhau los uas tsis tuaj yeem daws tau hauv Schnorr txoj hauv kev ntawm cov lej loj. Kev daws qhov tseem ceeb ntawm tus lej loj yog ib kauj ruam tseem ceeb hauv kev rhuav tshem RSA encryption algorithm.
Thaum daim ntawv yog lub suab zoo, cov kws tshaj lij hais tias nws nyuaj los ua pov thawj tias niaj hnub no quantum computers yuav ua rau kev txhim kho.
Thaum tsis muaj kev tshuaj xyuas qhia tias nws yuav nrawm dua, kuv xav tias qhov xwm txheej feem ntau yog tias nws tsis muaj kev txhim kho ntau, " hais tias MIT tus kws tshawb fawb Peter Shor.
RSA algorithm ua kom tsis pub leej twg paub ntawm ob tog sib pauv cov ntaub ntawv los ntawm cov yuam sij pej xeem thiab ntiag tug. Nws yog ob txoj kev ua haujlwm. Qhov no txhais tau hais tias muab cov ntaub ntawv encrypted thiab tus yuam sij ntiag tug, nws muaj peev xwm txiav txim siab cov ntawv nyeem.
Lub tswv yim hais tias quantum suav tuaj yeem rhuav tshem cov txheej txheem encryption suav tias "tsis tuaj yeem" los ntawm cov khoos phis tawj ib txwm tau thov los ntawm Shor hauv 1994.
Hashing Function Uncrackable, Tam sim no
SHA256, ntawm qhov tod tes, yog siv los xyuas kom meej tias cov ntaub ntawv tsis raug hloov. Nws yog ib lub ntsej muag ua haujlwm es tsis yog encryption algorithm.
Ntawm Bitcoin network, SHA256 pab ua pov thawj tias cov ntaub ntawv los ntawm kev lag luam thaiv tsis tau cuam tshuam nrog. Nws yog ib txoj hauv kev ua haujlwm, txhais tau tias cov zis tsis tuaj yeem siv los txiav txim siab cov tswv yim.
Thaum Shor txoj haujlwm tau ua pov thawj tias nws muaj peev xwm los daws qhov tseem ceeb ntawm tus lej loj, tsim lub hauv paus rau kev tawg RSA encryption, tsis paub cov algorithms txiav txim siab cov tswv yim ntawm hash muaj nuj nqi, muab nws cov zis. SHA-256 kuj tau hais tias yog kev sib tsoo-tiv taus, ua rau nws yuav luag tsis tuaj yeem nrhiav cov khoom siv sib txawv uas tau txais cov txiaj ntsig zoo ib yam.
Ib tug Bitcoin miner yuav tsum tsis tu ncua sib txawv ib tug xov tooj hu ua ib tug nonce mus tailor qhov tso zis ntawm ib tug SHA256 muaj nuj nqi xws li hais tias nws yog tsawg tshaj li ib tug predefined tooj. Tus lej, hu ua qhov nyuaj, tau hloov kho raws li cov miners siv sijhawm ntev npaum li cas los tsim cov khoom tsim nyog ntawm xyoo 2016 dhau los. Yog tias kev kwv yees qhov tseeb tso tawm ntawm qhov kawg 2016 blocks tau siv sijhawm ntev dua kaum feeb, ces Bitcoin algorithm ua rau lub hom phiaj nyuaj yooj yim dua los twv, thiab rov ua dua. Cov miner siv cov khoos phis tawj tshwj xeeb hu ua ASICs los ua kom muaj pes tsawg tus kwv yees ua tau hauv ib ob.
Lub Ib Hlis 2022 daim ntawv los ntawm University of Sussex tau hais tias lub computer quantum nrog 13 lab qubits "tawg Bitcoin encryption" hauv ib hnub, thaum tib txoj haujlwm yuav siv 300 lab qubit tshuab ib teev. Nws tsis paub meej tias daim ntawv hais txog tus kheej thiab pej xeem cov yuam sij los pauv Bitcoin lossis SHA256 hashing muaj nuj nqi.
IBM nthuav tawm Txoj Kev Zoo Tshaj Plaws
US multinational IBM thov kom muaj lub computer quantum haib tshaj plaws hauv ntiaj teb, nrog 433 qubits. Nws muaj kev npaj yuav tshaj tawm 1,000-qubit quantum computer hauv 2023 thiab 4,000-qubit tshuab hauv 2025.
Nyiv lub computer loj heev Fujitsu xav tias yuav xa lub teb chaws thawj 64-qubit quantum computer nyob rau lub caij nplooj ntoos hlav xyoo 2023. Nws nyuam qhuav sau ntawv tshiab. daim ntawv cog lus muab lub chaw Spanish xam nrog lub tshuab. Xyoo tas los, nws ntaus a deal nrog rau RIKEN lub koom haum tshawb fawb kom xa lub tshuab rau kev tshawb fawb kho mob.
Txawm li cas los xij, ib yam li cov kws tshawb fawb Suav, txhob tawg tuaj yeem ntog nrawm dua li qhov xav tau.
