Cov ntawv pov thawj digital tshaj tawm thiab sau tseg rau ntawm blockchain tuaj yeem hloov pauv hauv internet cov qauv kev nyab xeeb uas twb muaj lawm thiab muaj kev ruaj ntseg cov cim thiab kev sib cuam tshuam hauv lub neej. nChain Tus Thawj Coj ntawm Kev Tshawb Fawb Dr. Owen Vaughan tau hais rau CoinGeek txog lub cuab yeej uas nws lub tuam txhab tau tsim los tawm thiab txheeb xyuas cov ntaub ntawv pov thawj no, hais tias lawv tuaj yeem muaj ib hnub "ua lub hauv paus ntawm kev sib txuas, kev sib cuam tshuam thiab kev sib pauv hauv Web3."
"Nws yog peb lub hom phiaj ntawm nChain txhawm rau txhim kho kev ruaj ntseg thiab kev ceev ntiag tug ntawm cov cuab yeej muaj zog no," nws hais.
Dr. Vaughan tau hais txog lub ntsiab lus ntawm qhov kev nthuav qhia tsis ntev los no rau Philippines Securities thiab Exchange Commission (SEC) thiab luam tawm ib tsab xov xwm luv luv uas yog ib feem ntawm cov yeeb yaj kiab ntawm Web3 technologies nChain tau tsim. Raws li kev ua qauv qhia, nChain siv nws lub cuab yeej los muab "daim ntawv pov thawj txaus siab" rau Dr. Vaughan rau Philippines qhov kev tshwm sim. Daim ntawv pov thawj tau lees paub tias siv tau (lossis tsis yog) los ntawm BSV blockchain kev lag luam, nrog rau tus lej siv thiab lub sijhawm.
Txhua tus tso siab rau daim ntawv pov thawj digital
Yuav luag txhua tus neeg hauv ntiaj teb siv daim ntawv pov thawj digital-txawm lawv paub txog nws lossis tsis. Lawv tau siv los txheeb xyuas cov vev xaib feem ntau; feem ntau browsers hnub no yuav ceeb toom koj yog tias lub vev xaib tsis muaj. Lawv pab txhawb kev lag luam e-lag luam los ntawm kev sib txuas lus ntawm cov neeg siv, xws li kev them nyiaj online, kev lag luam, thiab kev yuav khoom. Lawv kuj tau txheeb xyuas tias cov software rub tawm thiab hloov kho tshiab, los ntawm cov khoos phis tawj PC yooj yim mus rau cov tswj hwm cov txheej txheem tseem ceeb, tuaj ntawm lawv cov neeg tsim tawm thiab tsis yog los ntawm tus neeg nyiag nkas tawm tsam "tus txiv neej-hauv nruab nrab" los ntawm zaum ntawm cov servers thiab cov neeg siv kawg.
Cov ntawv pov thawj no, muab los ntawm "cov ntaub ntawv pov thawj" uas ntseeg siab, yog ib qho piv txwv ntawm kev siv thev naus laus zis tab sis pom tsis tau siv li "cov kav dej." Lawv yog qhov tseem ceeb rau kev ceev ntiag tug thiab kev nyab xeeb, tab sis feem ntau cov neeg siv zoo tib yam tseem tsis nco qab seb lawv puas siv lawv lossis muaj nyob txhua qhov.
Tam sim no, daim ntawv pov thawj txoj cai (CA) siv cryptographic public key infrastructure (PKI) los muab daim ntawv pov thawj digital thiab khi nws tus yuam sij pej xeem rau nws tus neeg siv tus kheej.
Cov teeb meem tshwm sim los ntawm qhov tseeb tias CAs yog qhov chaw nruab nrab thiab feem ntau tsis muaj pob tshab hauv lawv txoj haujlwm. Yuav ua li cas yog tias CA tus kheej kev ruaj ntseg raug ua txhaum cai thiab daim ntawv pov thawj yuav tsum tau muab tshem tawm? (Qhov no tau tshwm sim yav dhau los; ntau qhov tom qab). Nyob rau hauv xyoo tas los no, cov txheej txheem kev txiav ntoo tshiab tau siv los txhim kho lub sijhawm teb thiab ua kom pom ntau dua ntawm CA cov txheej txheem sab hauv, tab sis cov no tseem cumbersome piv rau qhov uas lub blockchain-based system tuaj yeem ua tiav.
Cov neeg muab ntawv pov thawj (CAs) tuaj yeem tshem tawm daim ntawv pov thawj ntawm thaj chaw nyab xeeb lossis rau ntau qhov laj thawj, xws li daim ntawv pov thawj tsis xav tau ntxiv lawm. Txhawm rau kom paub tseeb tias daim ntawv pov thawj digital tam sim no siv tau lossis tsis yog, nws yuav tsum nug tus kws tshaj lij, uas Dr. Vaughan tau hais qhia txog kev siv nyiaj siv ua haujlwm thiab tsis pub dawb.
"(nChain's) cov cuab yeej tsis cuam tshuam nrog kev kos npe cryptographic, thiab yog li peb zam qhov nyuaj ntawm cov koom haum dhau los ua cov tub ceev xwm daim ntawv pov thawj hauv PKI," Dr. Vaughan tau hais. "Txawm li cas los xij, kev tshaj tawm thiab kev tshem tawm daim ntawv pov thawj tau sau tseg ntawm blockchain, muab kev txhim kho qib ntawm kev ncaj ncees."
Nws hais ntxiv tias cov cuab yeej siv thev naus laus zis tuaj yeem ua rau cryptographically ruaj ntseg yog tias lub koom haum tau npaj los ua daim ntawv pov thawj txoj cai.
"Peb ntseeg tias cov kev ntseeg siab no tseem ceeb dua hauv Web3. Peb tsis xav txog qhov 'trustless' ib puag ncig. Xwb, peb cov cuab yeej siv tau los txhim kho kev ntseeg siab uas peb muaj hauv cov koom haum thiab nce kev ceev ntiag tug. Piv txwv li, peb tsis tas yuav cia siab rau kev tswj hwm daim ntawv pov thawj tshem tawm cov npe tswj hwm los ntawm ntau lub hauv paus CAs. "
nChain cov cuab yeej siv blockchain kev lag luam tawm thiab tshem tawm daim ntawv pov thawj. Qhov no txhais tau tias kev txheeb xyuas lawv qhov kev siv tau yooj yim li kev txheeb xyuas seb puas muaj kev sib pauv lossis tsis tau. Zoo li lwm cov ntaub ntawv blockchain, daim ntawv pov thawj cov ntaub ntawv nws tus kheej tsis yog nyob rau hauv cov saw, tsuas yog ib txoj hlua plaintext uas txheeb xyuas seb daim ntawv pov thawj puas siv tau. Qhov no muaj txiaj ntsig zoo hauv kev ceev ntiag tug - cov neeg muab khoom thiab cov neeg siv yuav tsis xav tau daim ntawv pov thawj cov ntsiab lus lossis cov laj thawj rau pej xeem. Cov ntawv pov thawj pov thawj no yuav tsis xav kom tus neeg xa khoom lossis tus neeg paub paub tias lawv tau kuaj xyuas.
Nws yog kev ntseeg siab hauv blockchain nws tus kheej ua "qhov tseeb thoob ntiaj teb" uas ua rau cov ntaub ntawv pov thawj no ruaj ntseg. Nws kuj ua rau lawv muaj ntau yam: daim ntawv pov thawj tuaj yeem siv tsis yog hauv kev sib tham hauv online xwb, tab sis txhawm rau txheeb xyuas qhov tseeb hauv lub neej tiag tiag. Peb mam li tham txog cov no sai sai, tab sis ua ntej, cia saib seb yuav ua li cas rau hnub no daim ntawv pov thawj thiab CAs thaum muaj xwm txheej tsis zoo.
Lub npe nrov DigiNotar
Txhua tus uas tau ua raws li Dr. Craig S. Wright txoj haujlwm yeej paub lub npe DigiNotar, raws li nws tau hais ntau zaus. DigiNotar yog Dutch daim ntawv pov thawj uas tau tawm ntawm kev lag luam tom qab muaj kev ua txhaum cai hauv xyoo 2011. Qhov kev siv tau ua rau cov neeg thib peb tsis paub txog kev tshaj tawm cov ntawv pov thawj hauv cov npe ntawm DigiNotar cov neeg siv khoom, uas suav nrog cov npe loj xws li Mozilla, Google (NASDAQ: GOOGL), Yahoo! , WordPress, Txoj Haujlwm Tor, thiab Tsoomfwv Dutch.
Tib lub xyoo dhau los, Comodo Security Solutions, Inc. (tam sim no hu ua Xcitium) tau tshaj tawm tias tus neeg siv nyiaj ntawm ib qho ntawm nws cov koom haum sau npe tau raug kev ua txhaum cai, ua rau cuaj daim ntawv pov thawj dag ntawm xya lub vev xaib.
"Iranian hackers" tau ntiv tes rau DigiNotar thiab Comodo exploits (txawm hais tias, nrog rau ntau lwm yam hacks, nws kuj tuaj yeem yog ib tus neeg txhob txwm ua rau lawv tshwm sim). Lub ntsiab lus tseem ceeb ntawm no, txawm li cas los xij, yog cov lus teb rau qhov xwm txheej es tsis yog leej twg ua lub luag haujlwm. Thaum cov kev siv tau raug tshawb pom, nws yog nyob ntawm cov tuam txhab uas tsim cov software uas txheeb xyuas cov ntawv pov thawj (ie, web browsers) xa cov lus ceeb toom thiab teeb meem kev nyab xeeb, uas cov neeg siv yuav tsum tau nruab.
Qhov no tag nrho yuav siv sij hawm, tau kawg, thiab tsis muaj kev lees paub txhua tus neeg siv kawg yuav hloov kho lawv cov software ua ntej raug cuam tshuam. DigiNotar kuj tseem raug thuam rau ncua nws cov lus tshaj tawm txog cov ntawv pov thawj dag thiab tsis tuaj yeem lav tias nws tau tshem tawm tag nrho cov ntawv pov thawj tsis txaus ntseeg. Mozilla thiab Microsoft (NASDAQ: MSFT) tau xaiv tshem tawm DigiNotar daim ntawv pov thawj hauv paus los ntawm lawv cov browsers kom muaj kev nyab xeeb, uas tau tshem tawm ib daim ntawv pov thawj DigiNotar tau tshaj tawm hauv nws 13 xyoo kev lag luam. Lawm, qhov no ua rau muaj kev cuam tshuam ntau rau ntau tus neeg ntau dua li nws yuav tsum muaj.
Zaj lus qhia peb yuav tsum tau kawm los ntawm cov xwm txheej no yog, tsawg kawg, tias yuav tsum muaj txoj hauv kev nrawm dua thiab siv tau ntau dua los tshaj tawm cov ntawv ceeb toom thiab tshem tawm daim ntawv pov thawj. Kev ceeb toom tam sim thiab cov lus teb yuav zoo dua. Lub peev xwm los nug cov blockchain nodes (uas yog ua tau txawm tias niaj hnub no) tau txais cov lus teb tam sim ntawm daim ntawv pov thawj siv tau, txuag sijhawm thiab nyiaj txiag rau cov neeg koom nrog hauv cov txheej txheem, thiab lwm tus neeg cuam tshuam los ntawm nws hauv kab.
Siv tau daim ntawv pov thawj digital online thiab hauv lub neej tiag tiag
Tso cai rau ib lub koom haum los muab daim ntawv pov thawj blockchain (txawm lawv yog CA tau tso cai los yog tsis) muaj qhov cuam tshuam ntau dua, tsis yog hauv online xwb. Kev nrawm, pheej yig, thiab muaj peev xwm ua tau zoo li BSV blockchain tuaj yeem txhawb nqa 9,000 daim ntawv pov thawj, tshem tawm, lossis hloov tshiab ib ob. Txhua tus tuaj yeem nug cov ntaub ntawv blockchain txhawm rau txheeb xyuas qhov siv tau tam sim no.
Cov neeg xa khoom tuaj yeem tshem tawm daim ntawv pov thawj ntawm tus kheej nrog rau ib qho kev lag luam. Tus neeg tawm tswv yim tsis tas yuav ua rau tshem tawm txhua daim ntawv pov thawj uas lawv tau muab tawm txij li cov ntaub ntawv muab cov ntaub ntawv raug teem sijhawm. Nws tuaj yeem txiav txim siab seb daim ntawv pov thawj tau tshaj tawm ua ntej muaj kev ua txhaum cai los yog tsis tau, tso cai rau daim ntawv pov thawj tsis raug cuam tshuam kom siv tau.
Qhov kev txo nqi thiab kev ua tau zoo no txhais tau hais tias ntau lub koom haum tuaj yeem tawm / tshem tawm daim ntawv pov thawj digital - suav nrog feem ntau cov tuam txhab thiab tsoomfwv cov chaw haujlwm, tsev kawm qib siab thiab tsev kawm qib siab, lossis cov koom haum ntiag tug.
"Lub cuab tam yuav tso cai rau txhua lub koom haum muab ntawv pov thawj rau lawv cov neeg siv," Dr. Vaughan tau hais. "Qhov no tuaj yeem yog lub tsev kawm ntawv tau txais daim ntawv pov thawj ntawm kev kawm tiav, nws tuaj yeem yog tus tswv haujlwm muab daim ntawv pov thawj ntawm kev ua haujlwm, lossis nws tuaj yeem yog tsoomfwv lub koomhaum muab daim ntawv tso cai."
Rau qhov piv txwv ntawm tus neeg ua haujlwm tam sim no, tus tswv haujlwm tshiab tuaj yeem tshawb xyuas seb lawv tus neeg xam phaj puas tau qhia qhov tseeb los ntawm kev txheeb xyuas daim ntawv pov thawj qhia txog lawv txoj haujlwm tsis muaj tus neeg sib tw lossis lawv tus tswv haujlwm tam sim no paub. Nws muaj peev xwm txheeb xyuas kev ua tswv cuab ntawm qee lub koom haum tshwj xeeb, xws li lub club lossis lub koom haum nom tswv, yam tsis tau nthuav tawm lub koom haum lossis nws cov tswv cuab. Raws li tau hais dhau los, cov tsev kawm ntawv qib siab tuaj yeem muab cov ntawv pov thawj no los tsim kom muaj kev ruaj ntseg digital cov ntaub ntawv qib siab thiab lwm yam kev tsim nyog, xyuas kom meej tias ib tus neeg tau txais daim ntawv pov thawj uas lawv thov kom muaj.
Ib yam li niaj hnub no PKI-based CAs thiab cov ntawv pov thawj digital txheeb xyuas tus kheej thiab kev ntseeg siab hauv is taws nem, blockchain cov kev daws teeb meem zoo dua (siv nChain cov cuab yeej lossis lwm tus nyiam) tuaj yeem nthuav dav lawv cov txiaj ntsig dhau lub ntiaj teb online. Nws ua qhov no tib yam li qhov ua tau zoo tshaj plaws blockchain txhim kho ntau lwm cov txheej txheem - los ntawm kev ua kom lawv sai dua, pheej yig dua, thiab siv tau rau txhua tus.
Dr. Vaughan qhov kev nthuav qhia yog raws li cov ntaub ntawv tshawb fawb hu ua "A Scalable Bitcoin-based Public Key Certificate Management System" los ntawm Chloe Tartan, Craig Wright, Michaella Pettit, thiab Wei Zhang.
