Title (EN) METHOD AND APPARATUS FOR SECURE COMPUTING DEVICE START UP
(FR) PROCÉDÉ ET APPAREIL POUR DÉMARRER UN DISPOSITIF INFORMATIQUE SÉCURISÉ
Abstract:
(EN) The present invention provides methods and devices for secure computing device start up. The method includes generating a public / private key pair and signing a software image and obtaining a first time stamp and a second time stamp. The method further includes combining the signed software image, the first time stamp and the second time stamp into a bundle and deploying the bundle. During secure start up, the method includes authenticating the signed software image, the first time stamp and the second time stamp and booting the computing device if authentication passes. The computing device aborts booting the computing device if the authentication process fails.
(FR) La présente invention concerne des procédés et des dispositifs pour démarrer un dispositif informatique sécurisé. Le procédé comprend la génération d'une paire de clés publique/privée et la signature d'une image logicielle et l'obtention d'une première estampille temporelle et d'une deuxième estampille temporelle. Le procédé comprend en outre la combinaison de l'image logicielle signée, de la première estampille temporelle et de la deuxième estampille temporelle en un faisceau, et le déploiement du faisceau. Pendant le démarrage sécurisé, le procédé comprend l'authentification de l'image logicielle signée, de la première estampille temporelle et de la deuxième estampille temporelle et le démarrage du dispositif informatique si l'authentification réussit. Le dispositif informatique abandonne le démarrage du dispositif informatique si le processus d'authentification échoue.
