(KO) 암호 모듈을 갖는 전자 장치 및 그것의 암호연산 방법들
Abstract: front page image
(EN)An electronic device according to the present invention includes: a temporary password key manager for receiving a message encrypted with a temporary password key limited in the number of uses and determining whether the temporary password key is effective depending on whether a proof value corresponding to the temporary password key exists in a temporary password key table; and a code module including a decryption unit for not decrypting the encrypted message if the temporary password key is not effective.
(FR)L'invention porte sur un dispositif électronique qui comprend : un gestionnaire de clé de mot de passe temporaire (TPK) pour recevoir un message chiffré avec une clé de mot de passe temporaire limitée quant à son nombre d'utilisations et pour déterminer si la clé de mot de passe temporaire est efficace ou non en fonction de l'existence d'une valeur de preuve correspondant à la clé de mot de passe temporaire dans une table de clé de mot de passe temporaire ; un module de code comprenant une unité de déchiffrement pour ne pas déchiffrer le message chiffré si la clé de mot de passe temporaire n'est pas efficace.
(KO)본 발명에 따른 전자 장치는, 사용 회수의 제한을 갖는 임시 비밀키로 암호화된 메시지를 입력 받고, 상기 임시 비밀키에 대응하는 검증값이 임시 비밀키 테이블에 존재하는 지를 근거로 하여 상기 임시 비밀키가 유효한 지 판별하는 임시 비밀키 매니저; 및 상기 임시 비밀키가 유효하지 않다면, 상기 암호화된 메시지를 복호화하지 않는 복호화 유닛;을 포함하는 암호 모듈을 갖는다.
