Abstract:
(EN) The present invention relates to a method for security in an Internet-of-things environment. The method for context-based security by a service server in an Internet-of-things environment comprises the steps of: receiving context information from any one among terminals connected to a network system that constitutes an Internet-of-things environment, configuring an assess tree, encrypting data to be provided to the terminal that has provided the context information using the assess tree and a preset public key, generating a private key by combining the context information from the terminal and a preset master key, and providing the same to the terminal; checking, every time the terminal generates a data request including user and data identification information, whether or not there is stored decryption success information corresponding to the user and data identification information associated with the data request, transmitting data associated with the corresponding data identification information to the corresponding terminal in an unencrypted state if there is stored decryption success information corresponding to the user and data identification information, and transmitting data associated with the corresponding data identification information to the corresponding terminal in an encrypted state if there is no stored decryption success information corresponding to the user and data identification information; and, every time the terminal provides decryption success information corresponding to the user and data identification information, storing the same.
(FR) La présente invention concerne un procédé de sécurité dans un environnement de l'Internet des objets. Le procédé de sécurité contextuelle par un serveur de service dans un environnement de l'Internet des objets comprend les étapes suivantes : réception d'informations contextuelles de la part de l'un des terminaux connectés à un système de réseau qui constitue un environnement de l'Internet des objets, configuration d'un arbre d'évaluation, cryptage des données à fournir au terminal qui a fourni les informations contextuelles en utilisant l'arbre d'évaluation et une clé publique prédéfinie, génération d'une clé privée en combinant les informations contextuelles provenant du terminal et une clé maîtresse prédéfinie, et fourniture de celle-ci au terminal ; vérification, à chaque fois que le terminal génère une demande de données contenant des informations d'identification d'utilisateur et de données, s'il existe ou non des informations de réussite de décryptage stockées qui correspondent à l'utilisateur et des informations d'identification de données qui suivent la demande de données, transmission des données qui suivent les informations d'identification de données correspondantes au terminal correspondant dans un état non crypté s'il existe des informations de réussite de décryptage stockées correspondant à l'utilisateur et aux informations d'identification de données, et transmission des données qui suivent les informations d'identification de données correspondantes au terminal correspondant dans un état crypté s'il n'existe pas d'informations de réussite de décryptage stockées correspondant à l'utilisateur et d'informations d'identification de données ; et stockage de celles-ci à chaque fois que le terminal fournit des informations de réussite de décryptage correspondant à l'utilisateur et des informations d'identification de données.
(KO) 본 발명은 사물 인터넷 환경에서의 보안 방법에 관한 것이다. 상기 사물 인터넷 환경의 서비스 서버에 의한 컨텍스트 기반 보안방법은, 사물 인터넷 환경을 구성하는 네트워크 시스템에 연결된 단말기들 중 어느 하나로부터 컨텍스트 정보를 제공받아 어세스 트리를 구성하고, 상기 어세스 트리와 미리 설정된 공개키를 이용하여 상기 컨텍스트 정보를 제공한 단말기로 제공할 데이터를 암호화함과 아울러, 상기 단말기로부터의 컨텍스트 정보와 미리 설정된 마스터키를 조합하여 개인키를 생성하여 상기 단말기로 제공하는 단계; 상기 단말기로부터 유저 및 데이터 식별정보를 포함하는 데이터 요청이 발생될 때마다, 상기 데이터 요청에 따른 유저 및 데이터 식별정보에 대응되는 복호화 성공정보가 저장되어 있는지를 체크하고, 상기 유저 및 데이터 식별정보에 대응되는 복호화 성공정보가 저장되어 있다면, 해당 단말기로 해당 데이터 식별정보에 따른 데이터를 암호화되지 않은 상태로 전송하고, 상기 유저 및 데이터 식별정보에 대응되는 복호화 성공정보가 저장되어 있지 않다면, 해당 단말기로 해당 데이터 식별정보에 따른 데이터를 암호화된 상태로 전송하는 단계; 및 상기 단말기로부터 유저 및 데이터 식별정보에 대응되는 복호화 성공정보가 제공될 때마다 이를 저장하는 단계;를 포함한다.
