Tvrtka Google dodano<\/a><\/noindex> u glavni izvorni kod Androida kod s ugra\u0111enom podr\u0161kom za VPN WireGuard<\/a><\/noindex>. WireGuard kod je prenesen u modifikaciju Linux jezgre 5.4<\/a><\/noindex>, razvijene za budu\u0107e izdanje platforme Android 12, iz glavne Linux jezgre 5.6<\/a><\/noindex>, u kojem je izvorno bio usvojen<\/a><\/noindex> WireGuard. Podr\u0161ka za WireGuard na razini jezgre uklju\u010dena je prema zadanim postavkama<\/a><\/noindex>. <\/p>\n

Do sada su programeri WireGuard za Android nudili<\/a><\/noindex> mobilnu aplikaciju koja je ve\u0107 uklonjena<\/a><\/noindex> od strane Googlea iz Google Play trgovine zbog poveznice na stranicu za donacije na web mjestu projekta, koja je kr\u0161ila pravila o pla\u0107anjima (donacije su ozna\u010dene kao nedopu\u0161tene ako ih prikuplja neprofitna organizacija koja nije posebno registrirana).<\/p>\n

Podsjetimo, VPN WireGuard implementiran je na temelju suvremenih metoda \u0161ifriranja, jam\u010di vrlo visoke performanse, jednostavan je za kori\u0161tenje, oslobo\u0111en komplikacija i dobro se pokazao u brojnim velikim implementacijama koje obra\u0111uju velike koli\u010dine prometa. Projekt se razvija od 2015. godine, pro\u0161ao je audite i formalnu verifikaciju<\/a><\/noindex> primijenjenih metoda \u0161ifriranja. U WireGuardu se koristi koncept usmjeravanja temeljenog na \u0161ifriranim klju\u010devima, koji podrazumijeva vezivanje privatnog klju\u010da za svaki mre\u017eni su\u010delje i primjenu otvorenih klju\u010deva za povezivanje.<\/p>\n

Razmjena otvorenih klju\u010deva za uspostavljanje veze odvija se analogno s SSH-om. Za dogovor o klju\u010devima i povezivanje bez pokretanja posebnog demona u korisni\u010dkom prostoru koristi se Noise_IK mehanizam iz Noise Protocol Framework<\/a><\/noindex>, sli\u010dan odr\u017eavanju authorized_keys u SSH. Prijenos podataka odvija se putem enkapsulacije u UDP pakete. Podr\u017eava se promjena IP adrese VPN poslu\u017eitelja (roaming) bez prekida veze s automatskom ponovnom konfiguracijom klijenta.<\/p>\n

Za \u0161ifriranje koristi se<\/a><\/noindex> stream cipher ChaCha20<\/a><\/noindex> i algoritam za autentifikaciju poruka (MAC) Poly1305<\/a><\/noindex>, razvijeni od strane Daniela Bernsteina (Daniel J. Bernstein<\/a><\/noindex>), Tanje Lange
\n(Tanja Lange) i Petera Schwabea (Peter Schwabe). ChaCha20 i Poly1305 se predstavljaju kao br\u017ei i sigurniji analozi AES-256-CTR i HMAC, \u010dija softverska implementacija omogu\u0107uje postizanje fiksnog vremena izvr\u0161avanja bez kori\u0161tenja posebne hardverske podr\u0161ke. Za generiranje zajedni\u010dkog tajnog klju\u010da koristi se protokol Diffie-Hellman na elipti\u010dnim krivuljama u implementaciji Curve25519<\/a><\/noindex>, tako\u0111er predlo\u017een od strane Daniela Bernstein-a. Za hashiranje se koriste algoritmi BLAKE2s (RFC7693)<\/a><\/noindex>. <\/p>\n
