Title (EN) METHOD FOR INITIALIZING DEVICE HAVING ENHANCED SECURITY FUNCTION AND METHOD FOR UPDATING FIRMWARE OF DEVICE
(FR) PROCÉDÉ D'INITIALISATION DE DISPOSITIF AVEC FONCTION DE SÉCURITÉ RENFORCÉE ET PROCÉDÉ DE MISE À JOUR DE MICROPROGRAMME DE DISPOSITIF
(KO) 보안 기능이 강화된 디바이스의 초기화 방법 및 디바이스의 펌웨어 업데이트 방법
Abstract: front page image
(EN)A method for initializing a device, which is managed by an authorized manager, comprises the steps of: maintaining a security module coupled to a device by a hardware, and an encrypted firmware image; loading the encrypted firmware image; reading a header of the encrypted firmware image by using a public key, which is stored in the security module, of a manager, and confirming the integrity of the encrypted firmware image; decoding, by using a secret key of the security module, an symmetrical key encrypted by using the public key of the security module in the encrypted firmware image when the integrity of the encrypted firmware image is confirmed; decoding encrypted firmware in the encrypted firmware image by using the decoded symmetrical key; and executing the decoded firmware in the device.
(FR)L'invention concerne un procédé d'initialisation d'un dispositif, qui est géré par un gestionnaire autorisé, comportant les étapes consistant à: maintenir un module de sécurité couplé à un dispositif par un matériel, et une image de microprogramme chiffré; charger l'image de microprogramme chiffré; lire un en-tête de l'image de microprogramme chiffré en utilisant une clé publique, qui est stockée dans le module de sécurité, d'un gestionnaire, et confirmer l'intégrité de l'image de microprogramme chiffré; décoder, en utilisant une clé secrète du module de sécurité, une clé symétrique chiffrée en utilisant la clé publique du module de sécurité dans l'image de microprogramme chiffré lorsque l'intégrité de l'image de microprogramme chiffré est confirmée; décoder un microprogramme chiffré présent dans l'image de microprogramme chiffré en utilisant la clé symétrique décodée; et exécuter le microprogramme décodé dans le dispositif.
(KO)권한을 가진 관리자(Authorized Manager)에 의해서 관리되는 디바이스의 초기화 방법은, 디바이스에 하드웨어로 결합된 보안 모듈 및 암호화된 펌웨어 이미지를 유지하는 단계, 암호화된 펌웨어 이미지를 로딩하는 단계, 보안 모듈에 저장된 관리자의 공개 키를 이용하여 암호화된 펌웨어 이미지의 헤더를 읽어 암호화된 펌웨어 이미지의 무결성(integrity)을 확인하는 단계, 암호화된 펌웨어 이미지의 무결성이 확인되면 보안 모듈의 비밀 키를 이용하여 암호화된 펌웨어 이미지 중 보안 모듈의 공개 키를 이용하여 암호화된 대칭 키를 복호화하는 단계, 복호화된 대칭 키를 이용하여 암호화된 펌웨어 이미지 중 암호화된 펌웨어를 복호화하는 단계, 및 복호화된 펌웨어를 디바이스에 실행하는 단계를 구비한다.
