La soci\u00e9t\u00e9 Google ajout\u00e9<\/a><\/noindex> dans la base de code principale d'Android, le code avec support VPN int\u00e9gr\u00e9 WireGuard<\/a><\/noindex>. Le code de WireGuard a \u00e9t\u00e9 int\u00e9gr\u00e9 dans une modification du noyau Linux 5.4<\/a><\/noindex>, d\u00e9velopp\u00e9e pour la prochaine version de la plateforme Android 12, \u00e0 partir du noyau principal de Linux 5.6<\/a><\/noindex>, dans lequel il y avait \u00e0 l'origine adopt\u00e9<\/a><\/noindex> WireGuard. Le support de WireGuard fonctionnant au niveau du noyau est activ\u00e9 par d\u00e9faut<\/a><\/noindex>. <\/p>\n

Jusqu'\u00e0 pr\u00e9sent, les d\u00e9veloppeurs de WireGuard pour Android ont propos\u00e9<\/a><\/noindex> une application mobile, qui a d\u00e9j\u00e0 \u00e9t\u00e9 retir\u00e9e<\/a><\/noindex> par Google du catalogue Google Play en raison d'un lien vers la page de collecte de dons sur le site du projet, qui violait les r\u00e8gles sur les paiements (les dons sont consid\u00e9r\u00e9s comme inappropri\u00e9s s'ils sont collect\u00e9s par une organisation \u00e0 but non lucratif non enregistr\u00e9e).<\/p>\n

Rappelons que le VPN WireGuard est bas\u00e9 sur des m\u00e9thodes de chiffrement modernes, offre une tr\u00e8s haute performance, est facile \u00e0 utiliser, d\u00e9pourvu de complications et a bien r\u00e9ussi dans plusieurs grandes mises en \u0153uvre traitant de gros volumes de trafic. Le projet se d\u00e9veloppe depuis 2015, a \u00e9t\u00e9 audit\u00e9 et v\u00e9rification formelle<\/a><\/noindex> m\u00e9thodes de chiffrement appliqu\u00e9es. WireGuard utilise le concept de routage par cl\u00e9s de chiffrement, qui implique l'association d'une cl\u00e9 priv\u00e9e \u00e0 chaque interface r\u00e9seau et l'utilisation des cl\u00e9s publiques pour \u00e9tablir les connexions.<\/p>\n

L'\u00e9change de cl\u00e9s publiques pour \u00e9tablir la connexion se fait de mani\u00e8re similaire \u00e0 SSH. Pour la n\u00e9gociation des cl\u00e9s et la connexion sans lancer de d\u00e9mon s\u00e9par\u00e9 dans l'espace utilisateur, le m\u00e9canisme Noise_IK est utilis\u00e9 Noise Protocol Framework<\/a><\/noindex>, semblable au maintien des authorized_keys dans SSH. La transmission des donn\u00e9es se fait via encapsulation dans des paquets UDP. Le changement d'adresse IP du serveur VPN (roaming) est pris en charge sans rupture de la connexion, avec une reconfiguration automatique du client.<\/p>\n

Pour le cryptage on utilise<\/a><\/noindex> un chiffre de flux ChaCha20<\/a><\/noindex> et un algorithme d'authentification de message (MAC) Poly1305<\/a><\/noindex>, d\u00e9velopp\u00e9s par Daniel Bernstein (Daniel J. Bernstein<\/a><\/noindex>), Tanja Lange
\n(Tanja Lange) et Peter Schwabe (Peter Schwabe). ChaCha20 et Poly1305 sont pr\u00e9sent\u00e9s comme des alternatives plus rapides et plus s\u00e9curis\u00e9es \u00e0 AES-256-CTR et HMAC, dont l'impl\u00e9mentation logicielle permet d'obtenir un temps d'ex\u00e9cution fixe sans n\u00e9cessiter de support mat\u00e9riel particulier. Pour g\u00e9n\u00e9rer une cl\u00e9 secr\u00e8te partag\u00e9e, le protocole de Diffie-Hellman sur des courbes elliptiques est utilis\u00e9, impl\u00e9ment\u00e9 par Curve25519<\/a><\/noindex>, \u00e9galement propos\u00e9 par Daniel Bernstein. Pour le hachage, l'algorithme BLAKE2s (RFC7693)<\/a><\/noindex>. <\/p>\n
