Key Takeaways
- WhatsApp yog beta sim ntau lub cuab yeej muaj peev xwm nrog pab pawg me ntawm cov neeg siv.
- Tus yam ntxwv tshiab yuav tso cai rau cov neeg siv sib txuas lus sib txuas lus hla plaub yam khoom siv ntxiv.
- Cov kws tshaj lij hais tias tuaj yeem muaj kev lag luam ntiag tug thaum sib txuas lus thoob plaws cov khoom siv, txawm tias thaum nkag mus.
Tom qab nws tshaj tawm Lub Xya Hli tias ntau lub cuab yeej muaj peev xwm nyob hauv beta, WhatsApp cov neeg siv tau zoo siab rau lub tswv yim ntawm kev tuaj yeem nkag mus hla ntau lub cuab yeej. Tab sis puas yuav yooj yim ntxiv tuaj nrog kev sib pauv rau kev ceev ntiag tug? Nov yog yam koj yuav tsum paub.
Txawm hais tias nws tau txais kev lees paub encryption raws tu qauv, cov xov tooj nrov nrov tau raug hluav taws kub ob peb zaug hauv xyoo tas los no (thiab, er, nag hmo) rau ntau qhov tsis zoo, tsa cov lus nug txog nws txoj kev ruaj ntseg. Cov kws tshaj lij ceeb toom kuj tseem tuaj yeem muaj kev lag luam tawm thaum txuas ntau lub cuab yeej mus rau ib qho kev sib txuas lus encrypted app.
"[Cov lus nug] tsis yog tsuas yog ntxiv cov khoom siv ntxiv xwb, tab sis lawv puas muaj kev nyab xeeb ib txwm?" Steven M. Bellovin, tus kws tshaj lij computer science ntawm Columbia University, hais rau Lifewire hauv kev xam phaj hauv xov tooj. "Cov kab lus kev ruaj ntseg yog 'qhov chaw tawm tsam'-hauv pes tsawg qhov chaw koj tuaj yeem tawm tsam, thiab muaj pes tsawg txoj kev sib txawv?"
Technically Secure
Raws li Bellovin, ib qho ntawm cov teeb meem nyuaj dua los hais txog kev ruaj ntseg ntau yam khoom siv hauv ib tus as khauj pib nrog lub hauv paus ntawm kev encryption.
"Txhua qhov kev encryption nyob ntawm tus yuam sij zais cia," Bellovin hais tias, piv cov yuam sij encryption rau cov yuam sij tsheb uas tuaj yeem pib lub tsheb uas lawv koom nrog. "Txhua tus neeg yuav tsum muaj lawv tus kheej. Yog vim li cas koj thiaj nyeem tau thiab tsis muaj leej twg ua tau."
Vim tias txhua lub app uas tso siab rau qhov kawg-rau-kawg encryption (E2EE) siv cov txheej txheem tshwj xeeb raws li cov hauv paus ntsiab lus ntawm kev tuav cov ntsiab lus thiab lub npe (qhov kawg feem ntau yog tus neeg siv tus lej xov tooj), Bellovin hais tias qhov kev sib tw yog nrhiav txoj hauv kev kom ruaj ntseg txav cov yuam sij thiab txheeb xyuas tus tswv ntawm ntau yam khoom siv-ib yam uas nws hais tias "tsis yog lo lus nug yooj yim."
Keys to the Kingdom
Zoo li nws cov neeg sib tw, WhatsApp twb tso cai rau cov neeg siv nkag mus rau hauv lub khoos phis tawj kom ntev li ntev tau lawv tseem nkag mus rau hauv lub xov tooj smartphone cuam tshuam nrog lawv qhov tseem ceeb (lub tuam txhab hais tias nws thiaj li tsom iav tus account). Raws li beta system, txawm li cas los xij, txhua lub cuab yeej synced yuav muaj nws tus kheej qhov tseem ceeb- tso cai rau cov neeg siv nkag mus rau plaub yam khoom siv ntxiv yam tsis muaj xov tooj.
[Cov lus nug] tsis yog tsuas yog ntxiv cov khoom siv ntxiv xwb, tab sis lawv puas muaj kev nyab xeeb ib txwm?
"E2EE ib txwm siv ib tus yuam sij encryption rau ib tus neeg siv, leej twg yuav tsum luam tus yuam sij rau txhua lub cuab yeej lawv xav siv… Yog vim li cas WhatsApp, txog tam sim no, tsuas yog txhawb nqa ib lub cuab yeej-vim tias nws nyuaj rau khaws qhov encryption. key nyab xeeb thiab ruaj ntseg thaum tsiv mus rau ntau yam khoom siv, "John S. Koh, tus kws tshawb fawb txog kev nyab xeeb uas nws txoj haujlwm tau tsom mus rau ntau lub cuab yeej E2EE txoj hauv kev hu ua ib-device yuam sij (PDK), hais rau Lifewire hauv email.
"Nrog PDK, tsis yog cov neeg siv tsuas muaj ib tus yuam sij encryption xwb, txhua tus neeg siv cov khoom siv nws tus kheej encryption key. WhatsApp zoo li coj lub tswvyim no thiab hais txog cov yuam sij ntaus ntawv raws li 'tus yuam sij, '" Koh hais. "Ib qho ntawm cov txiaj ntsig ntawm E2EE ntawm ntau yam khoom siv siv kuv, thiab xav tias WhatApp's, txoj hauv kev vam khom rau ib qho tseem ceeb ntawm ib lub cuab yeej, yog tias cov qauv siv tau yooj yim dua rau cov neeg siv nkag siab. yuav tsum tau tshem tawm nws txoj kev nkag mus, uas qee zaum tuaj yeem ua haujlwm hnyav."
Ntau cov khoom siv, Kev daws tib yam
"Cov lus teb rau seb ib yam dab tsi ruaj ntseg ib txwm pib nrog lwm lo lus nug, uas yog, 'Koj xav tau dab tsi?'" Maritza Johnson, tus kws tshaj lij kev nyab xeeb thiab kev ceev ntiag tug thiab tus thawj coj hauv tsev kawm qib siab San Diego, hais rau Lifewire hauv kev xam phaj hauv xov tooj.
Txhawm rau hais txog qhov xav tau kev nyab xeeb ntawm tus kheej, Facebook tau hais hauv blog tshaj tawm tias WhatsApp npaj yuav muab lub peev xwm los saib txhua yam khoom siv txuas nrog tus account, saib thaum twg lawv tau siv zaum kawg, thiab tawm mus deb-ib yam Johnson tau hais tias tseem ceeb, tshwj xeeb tshaj yog rau cov neeg raug tsim txom ntawm tus khub kev tsim txom uas qee zaum yog lub hom phiaj ntawm cyberstalking.
"Koj tsis xav kom koj tus qub hluas nraug lub xov tooj tau txais daim ntawv luam ntawm txhua yam thiab koj tsis paub, lossis koj tsis paub yuav kaw nws li cas," Johnson hais. "Nws yog qhov kev txiav txim siab ntawm tus kheej, yog tias koj xav kos npe rau hauv koj tus lej WhatsApp ntawm ib lub cuab yeej sib koom, thiab xav txog qhov cuam tshuam ntawm qhov ntawd yuav yog dab tsi."
Johnson tseem tau hais txog qhov tseem ceeb ntawm kev ua kom txhua lub cuab yeej txuas tau tiv thaiv tus password kom tsis txhob muaj lwm tus neeg lub cev nkag mus rau nws-ib yam dab tsi uas muaj zog tshaj encryption tiv thaiv tsis tau.
"Txhua lub laptop, ntsiav tshuaj, lossis lwm yam khoom siv uas koj siv nrog tib tus account, koj yuav xav paub tseeb tias koj muaj tib theem kev ruaj ntseg ntawm tag nrho cov … yog li ntawd qee tus neeg tuaj yeem ' t cia li los so kom qhib," Johnson hais.
