Abstract:
(EN) The present invention relates to a method for transmitting a P2P file through enhanced security. According to one embodiment of the present invention, the method for transmitting a P2P file through enhanced security comprises: a comparison key issuing-request reception step (S100) of receiving, by a server (100), a comparison key issuing-request from a first client, wherein the first client is a transmitting client (200) or a receiving client (300); a step (S200) of receiving, by the server (100), a transmission request for a specific file from the transmitting client (200); a comparison key generation step (S300) of generating, by the server (100), a comparison key, wherein the comparison key is a combination of basic keys having n characters, which are randomly extracted, and special keys having m characters calculated by applying a specific generation rule for the n characters, and m and n are natural numbers; an input key reception step (S400) of receiving an input key from a second client, wherein the second client is one or more clients excluding the first client; and a step (S500) of determining whether to transmit a file by comparing the comparison key with the input key. According to the present invention, it is possible to limit the generation of a comparison key enabling a file transmission connection with a third client, instead of an intended first client, according to the incorrect input by users.
(FR) La présente invention se rapporte à un procédé permettant de transmettre un fichier de poste à poste (P2P) grâce à une sécurité améliorée. Selon un mode de réalisation de la présente invention, le procédé permettant de transmettre un fichier de poste à poste (P2P) grâce à une sécurité améliorée comprend : une étape de réception de demande de distribution de clé de comparaison (S100) consistant à recevoir, au moyen d'un serveur (100), une demande de distribution de clé en provenance d'un premier client, le premier client étant un client de transmission (200) ou un client de réception (300) ; une étape (S200) consistant à recevoir, au moyen du serveur (100), une demande de transmission d'un fichier spécifique du client de transmission (200) ; une étape de génération de clé de comparaison (S300) consistant à générer, au moyen du serveur (100), une clé de comparaison, la clé de comparaison étant une combinaison de touches de base ayant n caractères, qui sont extraits de manière aléatoire, et de touches spéciales ayant m caractères calculés par application d'une règle de génération spécifique pour les n caractères, et m et n étant des nombres entiers naturels ; une étape de réception de clé d'entrée (S400) consistant à recevoir une clé d'entrée en provenance d'un deuxième client, le deuxième client étant un ou plusieurs clients à l'exclusion du premier client ; et une étape (S500) consistant à déterminer s'il faut, ou non, transmettre un fichier en comparant la clé de comparaison avec la clé d'entrée. Selon la présente invention, il est possible de limiter la génération d'une clé de comparaison permettant une connexion de transmission de fichier avec un troisième client, au lieu d'un premier client prévu, en fonction de l'entrée incorrecte par des utilisateurs.
(KO) 본 발명은 보안성이 강화된 P2P파일 전송방법에 관한 것이다. 본 발명의 일실시예에 따른 보안성이 강화된 P2P파일 전송방법은, 서버(100)가 제1클라이언트로부터 비교키 발급요청을 수신하되, 상기 제1클라이언트는 송신클라이언트(200) 또는 수신클라이언트(300)인, 비교키발급요청 수신단계(S100); 서버(100)가 송신클라이언트(200)로부터 특정한 파일의 전송요청을 수신하는 단계(S200); 서버(100)가 비교키를 생성하는 단계로서, 상기 비교키는 임의로 추출된 n개의 문자로 된 기본키 및 상기 n개의 문자에 대해 특정한 생성규칙을 적용하여 산출된 m개의 문자인 특수키가 결합된 것이며, m과 n은 자연수인, 비교키생성단계(S300); 제2클라이언트로부터 입력키를 수신하되, 상기 제2클라이언트는 상기 제1클라이언트 이외의 하나 이상의 클라이언트인, 입력키 수신단계(S400); 및 상기 비교키와 상기 입력키를 비교하여 파일전송여부를 결정하는 단계(S500);를 포함한다. 본 발명에 따르면, 사용자들이 오입력함에 따라 의도한 제1클라이언트가 아닌 제3클라이언트와의 파일전송 연결될 수 있는 비교키의 발생을 제한할 수 있다.
