Iqela leProtonMail lazisile kwiposti yebhlog ukuba inkonzo yakho ye-imeyile ekhuselekileyo ngoku ixhasa i-elliptic curve cryptography (ECC) ukonyusa ukhuseleko kunye nesantya.
Ngokwiposti yebhlog, inkampani isebenze iinyanga ezininzi ukuseta inkxaso ngeendlela ezintsha zokubhala ezibonelela ngamava akhawulezileyo ngokhuseleko olulinganayo okanye olukhulu.
I-ECC iza kwiProtonMail
I-Elliptic curve cryptography yeyona nkqubo iphambili ye-cryptographic efumanekayo kwaye iqela leProtonMail ngoku lenza ukuba obu buchwephesha bufumaneke kubo bonke abasebenzisi kuyo yonke iwebhu, usetyenziso lweselfowuni kunye nedesktop yenkonzo ye-imeyile.
IProtonMail yakhele igama ngokhuseleko lwe-imeyile, imfihlo kunye nokusetyenziswa ngokulula.
Inkampani yenze isigqibo sokubandakanya i-elliptic curve crypto ukongeza kwi-RSA encryption. Nangona kunjalo, ngoku I-ECC iya kuba ngumgangatho osilelayo kuzo zonke iidilesi ezintsha kwiProtonMail kwaye iqela leProtonMail linika abasebenzisi abakhoyo ngoku, ngokuthumela iposti yabo yebhlog, ithuba lokuhlaziya iidilesi zabo zoMzantsi Afrika.
I-ECC yenye yezona ntlobo zinamandla ze-crypto.
Sisizukulwane esilandelayo sokushicilela isitshixo esidlangalaleni, kwaye isekwe kwimathematics. Inika isiseko esikhuseleke ngakumbi kunesizukulwane sokuqala seenkqubo eziphambili zokubhaliweyo kwi-RSA.
I-ECC inokuba ngumgangatho wexesha elizayo
Ngakumbi nangakumbi iiwebhusayithi zisebenzisa i-ECC ukukhusela yonke into kunxibelelwano lwabathengi lwe-HTTPS kwindlela yedatha ehanjiswa ngayo phakathi kwamaziko edatha.
Ngokweqela leProtonMail, ukuba umsebenzisi ukhathazekile ngokuqinisekisa elona nqanaba liphezulu lokhuseleko ngelixa ugcina ukusebenza, i-ECC lukhetho olufanelekileyo.
Ngokwiposti yebhlog, abasebenzisi kusenokwenzeka ukuba sele beyisebenzisa le crypto kwezinye iinkonzo, njenge-WhatsApp, i-Chrome, iFirefox, iOpera kunye neTor.
Inkqubo esekwe kwi-RSA esekwe kwinkqubo yokubhala ngokufihlakeleyo, ikwasekwe kwimathematika, ibiyimigangatho ebaleni kumashumi eminyaka.
I-Elliptical Curve Cryptography (ECC) ikhuseleke ngakumbi
Ngokweqela le-PrtonMail, iinkqubo eziphambili ze-cryptosystems, nokuba zinee-curve ze-RSA okanye ii-curve ze-elliptical, zikhuseleke kakhulu.
Nangona kunjalo, ekuphela kwendlela esebenzayo yokuba abahlaseli baqhekeze nayiphi na inkqubo yokubhala ngokufihlakeleyo kukusebenzisa ubuthathaka bokumiliselwa kwayo, iqela labhala.
“Nge-ECC, zimbini kuphela iintlaselo ezaziwayo, enye isebenzisa ithuba lenkunkuma engenanto kwaye enye isebenzisa izinto ezinje ngokusetyenziswa kwamandla kwezixhobo ukuqokelela izalathiso kumaqhosha. Ezi zinto zimbini ziqondwa kakuhle kwaye ziye zathomalaliswa iminyaka, ”kubhala iqela.
“Sikhethe inkqubo yegophe elliptical ebizwa ngokuba yi-X25519, ekhawulezayo, ekhuselekileyo kwaye ingakumbi enganyangekiyo kuhlaselo lokungqamanisa. "Kulula ukuyiphumeza kwaye, ngento eyiyo, ayisiyiyo nayiphi na ibango lobunikazi," longeze iqela.
Ngelixa lokufika kweekhompyuter ze-quantum, inkampani yamkele izitshixo ze-ECC eya kuba ngamaqhosha emiyo kuzo zonke iidilesi ezintsha kwiProtonMail. Inkampani imema abasebenzisi esele benayo iakhawunti yeProtonMail ukuba bahlaziye amaqhosha abo eRSA kwidilesi nganye ye-imeyile.
Iiakhawunti ezindala ziya kuba nakho ukonwabela i-ECC
Ukuhlaziya iakhawunti yakho, sKuya kufuneka balandele le miyalelo ilandelayo:
- Qhagamshela kwiakhawunti yakho ekhoyo yeProtonMail
- Kuya kufuneka baye kuyo Useto
- ukufikelela imenyu ephambili
- cofa iqhosha «Yongeza iphasiwedi entsha» kwaye ukhethe idilesi ofuna ukongeza kuyo ECC kwaye ucofe ngokulandelayo
- Emva koko ukhethe "X25519 (Yala maxesha, Ngokukhawuleza, Ngokukhuselekileyo)" emva koko ucofe ukuvelisa amaqhosha . Baya kucelwa ukuba bafake iphasiwedi yeakhawunti.
- Kumqolo we-ECC iqhosha, cofa kwimenyu eyehlayo kwaye ukhethe "Yenza Okuphambili".
Oku kuyakwenza i-ECC isitshixo esingagqibekanga kule dilesi ye-imeyile.
Inkampani icebisa ukuba ungazicimi izitshixo ze-RSA ezindala, kuba ngokwenza njalo kuya kuphulukana namandla okubhala zonke ii-imeyile zakho ezikhoyo.
