Title (EN) BOOTLOADER LEVEL ENCRYPTION FOR SYSTEM BOOT DATA
(FR) CHIFFREMENT DE NIVEAU DE PROGRAMME D'AMORÇAGE POUR DONNÉES D'AMORÇAGE DE SYSTÈME
Abstract:
(EN) A method for decryption for system boot data, performed by a computing device is provided. The method includes performing, as part of a boot process of a computing device, a key exchange with a server, to obtain a key. The method includes decrypting, with the key, an encrypted portion of a boot volume, and continuing the boot process, using the decrypted portion of the boot volume.
(FR) L'invention concerne un procédé de déchiffrement de données d'amorçage de système qui est mis en œuvre par un dispositif informatique. Le procédé comprend l'exécution, en tant que partie d'un processus d'amorçage d'un dispositif informatique, d'un échange de clé avec un serveur pour obtenir une clé. Le procédé comprend le déchiffrement, avec la clé, d'une partie chiffrée d'un volume d'amorçage, et la poursuite du processus d'amorçage à l'aide de la partie déchiffrée du volume d'amorçage.
