Nrog ntau cov ntaub ntawv tseem ceeb hauv cov xov xwm tsis ntev los no, koj yuav xav tias koj cov ntaub ntawv tiv thaiv li cas thaum koj nyob online. Thaum koj mus rau ib lub vev xaib ua qee lub khw thiab sau koj tus lej credit card, vam tias, ob peb hnub, ib pob tuaj txog ntawm koj lub qhov rooj. Tab sis lub sijhawm ntawd ua ntej koj nias Order, koj puas xav paub tias kev ruaj ntseg online ua haujlwm li cas?
Lub hauv paus ntawm Kev Ruaj Ntseg Hauv Online
Nyob hauv nws daim ntawv yooj yim, kev ruaj ntseg online-kev ruaj ntseg uas tshwm sim ntawm lub computer thiab lub vev xaib-yog ua los ntawm ntau cov lus nug thiab cov lus teb. Koj ntaus lub vev xaib chaw nyob rau hauv ib qho browser, thiab tom qab ntawd tus browser nug qhov chaw ntawd los xyuas nws qhov tseeb. Lub vev xaib teb nrog cov ntaub ntawv tsim nyog, thiab tom qab ob qho tib si pom zoo, lub xaib qhib hauv lub vev xaib browser.
Ntawm cov lus nug thiab cov ntaub ntawv sib pauv yog cov ntaub ntawv hais txog hom encryption uas hla cov ntaub ntawv browser, cov ntaub ntawv hauv computer, thiab cov ntaub ntawv ntiag tug ntawm browser thiab lub vev xaib. Cov lus nug thiab lus teb no yog hu ua kev sib tuav tes. Yog tias qhov kev sib tuav tes tsis tshwm sim, ces lub vev xaib koj sim mus xyuas yog suav tias tsis muaj kev nyab xeeb.
HTTP vs
- Qhib rau leej twg pom txoj kev.
- Yooj yim teeb tsa thiab khiav.
- Tsis muaj kev ruaj ntseg rau lo lus zais thiab xa cov ntaub ntawv.
- Zoo encrypted kom zais cov ntaub ntawv.
- Yuav tsum muaj kev teeb tsa server ntxiv.
- Tiv thaiv cov ntaub ntawv xa mus, suav nrog tus password.
Ib yam koj yuav pom thaum koj mus saib cov vev xaib hauv lub vev xaib yog qee qhov muaj qhov chaw nyob pib nrog http, thiab qee qhov pib nrog https. HTTP txhais tau tias Hypertext Transfer Protocol; Nws yog cov txheej txheem lossis txheej txheem txheej txheem uas tsim kev sib txuas lus ruaj ntseg hauv internet.
Qee qhov chaw, tshwj xeeb tshaj yog qhov chaw uas koj raug hais kom muab cov ntaub ntawv rhiab lossis qhia tus kheej, tuaj yeem tso tawm https yog ntsuab lossis liab nrog kab los ntawm nws. HTTPS txhais tau tias Hypertext Transfer Protocol Secure, thiab ntsuab txhais tau tias lub xaib muaj daim ntawv pov thawj kev ruaj ntseg. Liab nrog ib kab los ntawm nws txhais tau hais tias lub xaib tsis muaj daim ntawv pov thawj kev nyab xeeb, lossis daim ntawv pov thawj tsis raug lossis tag sijhawm.
Ntawm no yog qhov uas muaj qhov tsis meej pem me ntsis. HTTP tsis txhais hais tias cov ntaub ntawv pauv ntawm lub computer thiab lub vev xaib raug encrypted. Nws tsuas yog txhais tau tias lub vev xaib uas sib txuas lus nrog browser muaj daim ntawv pov thawj kev ruaj ntseg. Tsuas yog thaum S(raws li hauv S) suav nrog yog cov ntaub ntawv xa mus nyab xeeb, thiab muaj lwm yam thev naus laus zis hauv kev siv uas ua rau muaj kev ruaj ntseg. ua tau.
SSL vs. TLS
- Thawj tsim tawm xyoo 1995.
- theem ua ntej ntawm lub vev xaib encryption.
- Lagged qab hauv internet loj hlob sai.
- Pib ua tus thib peb ntawm SSL.
- Txheej Txheej Kev Nyab Xeeb.
- Txuas ntxiv txhim kho ntawm kev siv encryption siv hauv SSL.
- Ntxiv kev ruaj ntseg kho rau hom tshiab ntawm kev tawm tsam thiab qhov kev nyab xeeb.
SSL yog thawj qhov kev ruaj ntseg raws tu qauv los xyuas kom meej tias cov vev xaib thiab cov ntaub ntawv hla ntawm qhov chaw muaj kev nyab xeeb. Raws li GlobalSign, SSL tau qhia hauv 1995 raws li version 2.0. Thawj version (1.0) yeej tsis tau ua nws rau hauv pej xeem sau. Version 2.0 tau hloov los ntawm version 3.0 nyob rau hauv ib xyoos los daws qhov tsis zoo hauv cov txheej txheem.
Hauv xyoo 1999, lwm qhov ntawm SSL, hu ua Transport Layer Security (TLS), tau qhia los txhim kho qhov ceev ntawm kev sib tham thiab kev ruaj ntseg ntawm kev sib tuav tes. TLS yog tus qauv uas tam sim no siv, tab sis nws feem ntau hu ua SSL rau qhov yooj yim.
Kev nkag siab SSL raws tu qauv
- Hides cov ntaub ntawv teeb tsa ntawm lub computer thiab lub vev xaib.
- Tiv thaiv cov ntaub ntawv nkag mus.
- Kev yuav khoom hauv online.
- Tsis tiv thaiv txhua yam kev hem thawj.
- Tsis muaj kev ruaj ntseg rau koj ntawm qhov chaw tsis siv SSL.
- Tsis tuaj yeem nkaum lub vev xaib twg koj mus ntsib.
Thaum koj xav txog kev sib koom tes nrog ib tus neeg, txhais tau tias muaj ob tog koom nrog. Kev ruaj ntseg hauv online yog ntau yam tib yam. Rau kev sib tuav tes uas ua kom muaj kev ruaj ntseg hauv online kom muaj qhov chaw, yuav tsum muaj ob tog koom nrog. Yog tias HTTPS yog tus txheej txheem uas lub web browser siv los xyuas kom meej tias muaj kev ruaj ntseg, ces qhov thib ob ntawm kev sib tuav tes yog cov txheej txheem uas ua kom muaj kev nkag mus.
Kev nkag mus yog thev naus laus zis uas tau siv los zais cov ntaub ntawv uas tau pauv ntawm ob lub cuab yeej hauv lub network. Nws tau ua tiav los ntawm kev hloov cov cim uas tau lees paub rau hauv qhov tsis paub txog gibberish uas tuaj yeem rov qab mus rau nws lub xeev qub uas siv tus yuam sij encryption. Qhov no yog thawj zaug ua tiav los ntawm kev siv tshuab hu ua Secure Socket Layer (SSL) kev ruaj ntseg.
SSL yog thev naus laus zis uas hloov cov ntaub ntawv hloov pauv ntawm lub vev xaib thiab browser mus rau gibberish thiab rov qab mus rau hauv cov ntaub ntawv dua. Nov yog nws ua haujlwm li cas:
- Koj qhib qhov browser thiab ntaus qhov chaw nyob rau koj lub txhab nyiaj.
- Lub vev xaib qhib lub txhab nyiaj lub qhov rooj thiab qhia koj.
- Tus neeg saib xyuas lub rooj lees paub tias koj yog tus uas koj hais tias koj yog thiab pom zoo tso cai rau koj nyob rau hauv ib qho xwm txheej.
- Lub vev xaib pom zoo rau cov xwm txheej, thiab tom qab ntawd koj raug tso cai nkag mus rau lub txhab nyiaj lub vev xaib.
Cov txheej txheem rov ua dua thaum koj nkag rau koj lub npe siv thiab tus password, nrog qee cov kauj ruam ntxiv.
- Koj sau koj tus username thiab password kom nkag mus rau koj tus as khauj.
- Koj lub vev xaib qhia rau tus thawj tswj nyiaj hauv tuam txhab nyiaj tias koj xav nkag mus rau koj tus as-qhauj.
- Lawv sib tham thiab pom zoo tias yog tias koj tuaj yeem muab cov ntaub ntawv pov thawj raug, ces koj yuav tau txais kev tso cai. Txawm li cas los xij, cov ntawv pov thawj yuav tsum tau nthuav tawm siv hom lus tshwj xeeb.
- Lub web browser thiab tus thawj tswj nyiaj hauv tuam txhab nyiaj pom zoo rau cov lus uas yuav siv.
- Lub web browser hloov koj lub npe siv thiab tus password rau hauv hom lus tshwj xeeb thiab xa mus rau tus thawj tswj nyiaj hauv tuam txhab nyiaj.
- Tus thawj tswj nyiaj tau txais cov ntaub ntawv, txiav txim siab nws, thiab muab piv rau lawv cov ntaub ntawv.
- Yog tias koj daim ntawv pov thawj sib tw, koj tau tso cai nkag mus rau koj tus as khauj.
txheej txheem yuav siv qhov chaw hauv nanoseconds, yog li koj tsis pom lub sijhawm nws siv rau kev sib tham thiab tuav tes los ua qhov chaw nruab nrab ntawm lub vev xaib thiab lub vev xaib.
TLS Encryption
- Kev nyab xeeb ntau ntxiv.
- Hides cov ntaub ntawv ntawm lub computer thiab lub vev xaib.
- txheej txheem tuav tes zoo dua thaum sib tham sib txuas lus encrypted.
- Tsis muaj kev nkag siab zoo meej.
- Tsis tau txais kev nyab xeeb DNS.
- Tsis tau tag nrog cov laus dua.
TLS encryption tau qhia los txhim kho cov ntaub ntawv kev nyab xeeb. Thaum SSL yog cov cuab yeej zoo, kev ruaj ntseg hloov pauv ntawm tus nqi nrawm, thiab qhov ntawd ua rau muaj kev xav tau kev ruaj ntseg zoo dua, hloov tshiab. TLS tau tsim nyob rau hauv lub moj khaum ntawm SSL nrog kev txhim kho rau cov algorithms uas tswj kev sib txuas lus thiab tuav tes.
TLS Version Puas Muaj Tam Sim No?
Raws li nrog SSL, TLS encryption tau txuas ntxiv txhim kho. Tam sim no TLS version yog 1.2, tab sis TLSv1.3 tau tsim, thiab qee lub tuam txhab thiab browsers tau siv kev ruaj ntseg rau lub sijhawm luv luv. Feem ntau, lawv rov qab mus rau TLSv1.2 vim tias version 1.3 tseem ua tiav.
Thaum ua tiav, TLSv1.3 yuav coj ntau yam kev txhim kho kev ruaj ntseg, suav nrog kev txhim kho kev txhawb nqa rau ntau hom kev encryption tam sim no. Txawm li cas los xij, TLSv1.3 tseem yuav tso tseg kev txhawb nqa rau cov laus ntawm SSL raws tu qauv thiab lwm yam kev ruaj ntseg technologies uas tsis muaj zog txaus los xyuas kom meej cov kev ruaj ntseg thiab encryption ntawm tus kheej cov ntaub ntawv.
