Le projet GNU a pr\u00e9sent\u00e9 la premi\u00e8re version de test de GNU Anastasis, un protocole et des applications avec sa mise en \u0153uvre, con\u00e7us pour un stockage s\u00e9curis\u00e9 des cl\u00e9s de cryptage et des codes d'acc\u00e8s. Le projet est d\u00e9velopp\u00e9 par les cr\u00e9ateurs du syst\u00e8me de paiement GNU Taler en r\u00e9ponse \u00e0 la n\u00e9cessit\u00e9 d'un outil pour restaurer des cl\u00e9s perdues \u00e0 la suite d'une d\u00e9faillance de stockage ou en raison d'un mot de passe oubli\u00e9 ayant servi \u00e0 chiffrer la cl\u00e9. Le code du projet est \u00e9crit en langage C et distribu\u00e9 sous la licence GPLv3. <\/p>\n

L'id\u00e9e principale du projet est que la cl\u00e9 est fragment\u00e9e en parts, et chaque part est chiffr\u00e9e et stock\u00e9e chez un fournisseur de stockage ind\u00e9pendant. Contrairement aux sch\u00e9mas de sauvegarde de cl\u00e9s existants, qui impliquent des services payants ou l'aide d'amis\/famille, la m\u00e9thode propos\u00e9e par GNU Anastasis ne repose pas sur une confiance totale envers le stockage ni sur la n\u00e9cessit\u00e9 de se souvenir d'un mot de passe complexe qui chiffre la cl\u00e9. La protection des sauvegardes de cl\u00e9s par des mots de passe n'est pas consid\u00e9r\u00e9e comme une solution, car il faut aussi stocker ou m\u00e9moriser le mot de passe (les cl\u00e9s seraient perdues \u00e0 cause d'une amn\u00e9sie ou de la mort du propri\u00e9taire). <\/p>\n

Le fournisseur de stockage dans GNU Anastasis ne peut pas utiliser la cl\u00e9 car il n'a acc\u00e8s qu'\u00e0 une partie de celle-ci, et pour rassembler tous les composants de la cl\u00e9 en un seul, il doit s'authentifier aupr\u00e8s de chaque fournisseur, qui utilise diff\u00e9rentes m\u00e9thodes d'authentification. L'authentification par SMS, par e-mail, la r\u00e9ception d'une lettre papier ordinaire, les appels vid\u00e9o, la connaissance de la r\u00e9ponse \u00e0 une question secr\u00e8te pr\u00e9d\u00e9finie et la possibilit\u00e9 d'effectuer un transfert depuis un compte bancaire pr\u00e9alablement sp\u00e9cifi\u00e9 sont prises en charge. Ces v\u00e9rifications confirment que l'utilisateur a acc\u00e8s \u00e0 son e-mail, \u00e0 son num\u00e9ro de t\u00e9l\u00e9phone et \u00e0 son compte bancaire, et peut \u00e9galement recevoir des lettres \u00e0 l'adresse indiqu\u00e9e.

\"GNU<\/center> <\/p>\n

Lors de la sauvegarde de la cl\u00e9, l'utilisateur choisit lui-m\u00eame les fournisseurs et les m\u00e9thodes d'authentification \u00e0 utiliser. Avant de transmettre les donn\u00e9es au fournisseur, une partie de la cl\u00e9 est chiffr\u00e9e \u00e0 l'aide d'un hachage, calcul\u00e9 \u00e0 partir des r\u00e9ponses formalis\u00e9es \u00e0 plusieurs questions li\u00e9es \u00e0 l'identit\u00e9 du propri\u00e9taire de la cl\u00e9 (nom complet, date et lieu de naissance, num\u00e9ro de s\u00e9curit\u00e9 sociale, etc.). Le fournisseur ne re\u00e7oit aucune information sur les utilisateurs qui effectuent la sauvegarde, \u00e0 l'exception des informations n\u00e9cessaires \u00e0 l'authentification du propri\u00e9taire. Une certaine somme peut \u00eatre vers\u00e9e au fournisseur pour le stockage (le support de tels paiements a d\u00e9j\u00e0 \u00e9t\u00e9 ajout\u00e9 dans GNU Taler, mais les deux fournisseurs de tests actuels fonctionnent gratuitement). Une utilitaire avec interface graphique bas\u00e9e sur la biblioth\u00e8que GTK a \u00e9t\u00e9 d\u00e9velopp\u00e9e pour g\u00e9rer le processus de r\u00e9cup\u00e9ration.
