Nyob rau hauv ib daim ntawv tshawb fawb hu ua "Factoring integers with sublinear sublinear resources on a superconducting quantum processor," ib pawg ntawm cov kws tshawb fawb Suav tau thov tias lawv tuaj yeem tawg RSA encryptions ntawm cov xov tooj, cov ntaub ntawv khaws cia, thiab cov tuam txhab lag luam siv quantum suav.
Nyob rau hauv lawv daim ntawv scientific, Cov kws tshawb fawb Suav thov tias lawv muaj factored ib 48-ntsis integer siv lawv cov txheej txheem ntawm quantum computer nrog kaum qubits, tab sis lawv tseem tsis tau sim ntsuas nws kom ua haujlwm ntawm lub kaw lus loj dua.
Qhov teeb meem kev ruaj ntseg, yog tias muaj tseeb
Qhov kev thov tau tshem tawm kev txhawj xeeb, feem ntau yog los ntawm cov kws tshaj lij hauv cybersecurity, cov ntaub ntawv thev naus laus zis, thiab qhov chaw crypto. Txawm li cas los xij, ntau tus kws tshaj lij no tau piav qhia qhov kev thov ua tsis tau. Cov kws tshawb fawb 24 kuj tau thov tias lawv siv lub tshuab quantum uas tsuas yog 372 qubits (quantum bits) thaum tawg cov cai.
Meanwhile, IBM twb tau hais tias lub computer muaj zog tshaj plaws quantum, 433 qubit Osprey system, yuav muab rau cov neeg siv khoom thaum ntxov xyoo no.
Cov kws paub txog kev ruaj ntseg hauv khoos phis tawj thiab cov kws sau ntawv tau qhia txog kev ntshai tias yog tus kws tshawb fawb tau ua tiav lawm, nws yuav yog lub sijhawm tseem ceeb hauv keeb kwm ntawm kev ruaj ntseg hauv computer.
Cov kws tshaj lij zoo li Peter Shor ntawm tus Massachusetts Lub koom haum thev naus laus zis thiab Andre Konig ntawm Decrypt, ntseeg hais tias thaum txoj kev xav tau teev nyob rau hauv daim ntawv kawm zoo li siv tau, muab tso rau hauv kev coj ua tej zaum yuav dhau hnub no lub peev xwm quantum technology.
Cov ntaub ntawv tshawb fawb tshiab kawg ua rau nws thib ob uas pab pawg kws tshawb fawb tau tuaj nrog cov lus thov hauv tsawg dua ib xyoos.
Nco qab tias Claus-Peter Schnorr, tus kws lej German, tau thov ib qho algorithm xyoo tas los uas nws tau hais tias yog ib txoj hauv kev ua tau zoo dua los ua tus lej tseem ceeb - qhov tseem ceeb rau kev tawg RSA system.
Txawm li cas los xij, nws cov lus thov thaum kawg ua tsis tiav los ntsuas RSA algorithms.
Qhov no txhais li cas rau crypto?
Vim hais tias cryptocurrencies thiab blockchain muaj ntau yam ua nrog encryptions, kev txhawj xeeb kuj tau tshwm sim txog hacking Bitcoin siv "brute force" ntawm quantum computers.
Lub tuam txhab Cybersecurity Kaspersky tau hais tias qhov kev tawm tsam no tuaj yeem siv sijhawm ntev vim tias kev tawm tsam brute quab yuam siv kev sim thiab yuam kev los twv cov hlua xws li nkag mus rau cov ntaub ntawv pov thawj thiab encryption yuam sij nrog kev cia siab ntawm kev nrhiav kev sib tw, thiab qhov kev sim no tuaj yeem ua tsis tau.
David Schwed, Tus Thawj Saib Xyuas Haujlwm ntawm Halborn, a blockchain kev ruaj ntseg ruaj, hais tias nws tsis yog crypto xwb; txhua yam nrog encryption yuav tsum muaj kev txhawj xeeb. Txawm li cas los xij, nws tsis ntseeg qhov muaj peev xwm ntawm cov kws tshawb fawb Suav.
