Raws li cov ntaub ntawv tshaj tawm thoob plaws hauv lub vev xaib, 24 tus kws tshawb fawb Suav tau tshaj tawm tias ua tiav RSA encryption siv lub computer quantum. Qhov no yuav yog qhov ua tiav tseem ceeb, vim RSA encryption tau siv dav hauv kev coj ua kev nyab xeeb tam sim no. Txawm li cas los xij, ntau tus kws tshaj lij, kws tshawb fawb hauv computer, thiab cryptographers tsis ntseeg tias cov kws tshawb fawb tau tshawb pom qhov tseem ceeb, raws li cov ntaub ntawv tshawb fawb tau luam tawm thaum Lub Kaum Ob Hlis 2022.
Quantum Computing Haiv Neeg Heats Up li Suav Cov Kws Tshawb Fawb tau thov kev tawg hauv RSA Encryption
Thaum lub Cuaj Hlis 2022, US Cybersecurity and Infrastructure Security Agency (CISA) ceeb toom tias lub ntiaj teb tom qab quantum tau los sai sai thiab tau hais tias cov txheej txheem encryption niaj hnub tuaj yeem tawg. Lub hlis tom qab, thaum lub Kaum Ob Hlis 2022, a daim ntawv scientific luam tawm los ntawm 24 tus kws tshawb fawb Suav tau lees tias tau tawg 2048-ntsis RSA encryption siv lub computer quantum. Daim ntawv ua raws li a daim ntawv qhia txij lub Plaub Hlis 2022 uas tau piav qhia tias Tuam Tshoj tau "ua tus thawj coj" hauv kev sib tw quantum suav.
Yeej, a quantum khoos phis tawj yog ib hom kev siv computer uas siv quantum-mechanical phenomena thiab tuaj yeem ua haujlwm ntawm cov ntaub ntawv sai dua li cov khoos phis tawj classical tuaj yeem ua cov haujlwm suav. RSA muaj npe tom qab nws tus tsim, Ron Rivest, Adi Shamir, thiab Leonard Adleman, thiab tau siv dav hauv cov tshuab computer niaj hnub no. Nws yog ib qho piv txwv ntawm pej xeem-key cryptography system, uas txhais tau hais tias niaj hnub computers feem ntau siv nws los encrypt thiab decrypt cov lus.
Lub Ib Hlis 5, 2023, Lub Sijhawm Nyiaj Txiag (FT) qhia nyob rau hauv daim ntawv uas liam cov kws tshawb fawb Suav tau lees tias muaj kev vam meej hauv kev rhuav tshem RSA encryption. FT nug ob peb tus kws tshaj lij txog daim ntawv, thiab Roger Grimes, tus kws tshaj lij kev ruaj ntseg hauv computer thiab tus kws sau ntawv, hais rau FT: "Nws yog qhov kev thov loj heev - Nws yuav txhais tau tias tsoomfwv tuaj yeem tsoo lwm tsoomfwv cov lus zais. Yog tias nws muaj tseeb - qhov loj yog tias - nws yuav yog qhov zais cia zoo li tawm ntawm cov yeeb yaj kiab, thiab yog ib qho loj tshaj plaws hauv computer science. "
Kuj tseem muaj Google Pawg sib tham qhov twg tib neeg tab tom sib cav seb cov kws tshawb fawb Suav tau ua rau hauv 2048-ntsis integers. Bruce schneier, tus kws tshaj lij kev ruaj ntseg hauv computer thiab crypto txiaj, luam tawm ib qho tsom xam thiab hais tias daim ntawv tso siab rau a ntawv sib cav sau los ntawm Peter Schnorr, ib tug German lej. Schneier kuj tau qhia nws txoj kev xav nrog Lub Sijhawm Nyiaj Txiag txog qhov hu ua quantum xam kev ua tiav. "Peb tsis muaj pov thawj pom tseeb tias [tshiab] quantum algorithm kov yeej qhov teeb meem Schnorr scaling," Schneier hais rau FT. "Tsis muaj laj thawj ntseeg tias nws yuav tsis yog - tab sis tsis muaj laj thawj ntseeg nws yuav."
Quantum xam lub peev xwm los rhuav tshem cov txheej txheem encryption niaj hnub no tau txhawj xeeb crypto cov neeg txhawb nqa rau qee lub sijhawm. Txawm li cas los xij, qee tus ntseeg tias yog quantum computers tuaj yeem rhuav tshem kev encryption, nws yuav yog ib qho kev tiv thaiv tsis pub lwm tus paub. Thaum nug yog tias nws xav tias lub khoos phis tawj quantum tuaj yeem rhuav tshem Bitcoin's cryptography, Bitcoin tshaj tawm Andreas Antonopoulos ib zaug hais tias, "Qhov kawg uas lawv yuav siv qhov ntawd yog Bitcoin." Antonopoulos ntxiv:
Ua rau lub sijhawm koj siv nws ntawm Bitcoin koj tshaj tawm rau lub ntiaj teb peb muaj quantum cryptography uas tuaj yeem ua txhaum [lub] elliptic nkhaus - Xum ua li cas? Koj cov neeg sib tw nuclear tau hloov kho lawv cov cryptography yooj yim heev thiab sim siv quantum-resistant cryptographic algorithms.
Hais lus nrog FT, tus kws tshaj lij cryptography Bruce Schneier xaus lus tias thaum cov kws tshawb fawb cov ntaub ntawv tuaj yeem hloov mus rau qhov tsis muaj peev xwm, kev sib tw rau lub computer quantum kom tawg encryption tau kub. Schneier tau hais tias "Qhov kev twv txiaj yog, zoo li txhua qhov xwm txheej no, kev rhuav tshem RSA yuav tsis ua haujlwm - tab sis muaj ib hnub qhov kev twv txiaj yuav tsis raug," Schneier tau hais.
Koj xav li cas txog cov lus ceeb toom txog cov kws tshawb fawb Suav uas tau lees paub tias muaj kev vam meej nrog kev rhuav tshem cov txheej txheem encryption niaj hnub nrog lub computer quantum? Qhia rau peb paub koj cov kev xav txog cov ncauj lus no hauv cov lus hauv qab no.
