Abstract: front page image
(EN)The present invention relates to a system and method for transmitting and receiving peer-to-peer message, and to a method for distributing a media key in the system. The system for transmitting and receiving peer-to-peer messages according to the present invention includes: a transmission client for adding a first media key issued by a reception-side relay server to media data, and transmitting the media data to the reception-side relay server; said reception-side relay server for issuing the first media key to the transmission client, receiving the media data from the transmission client, replacing the received first media key added to the media data with a second media key issued by a reception client , and transmitting the media data to the reception client; and said reception client for issuing the second media key to the reception-side relay server and for receiving the media data from the reception-side relay server.
(FR)La présente invention concerne un système et un procédé d'émission et de réception de messages d'homologue à homologue, et un procédé de distribution d'une clé multimédia dans le système. Le système d'émission et de réception de messages d'homologue à homologue de la présente invention comprend : un client d'émission destiné à ajouter à des données multimédia une première clé multimédia délivrée par un serveur relais côté réception, et à émettre les données multimédia vers le serveur relais côté réception ; ledit serveur relais côté réception étant destiné à envoyer la première clé multimédia au client d'émission, à recevoir les données multimédia du client d'émission, à remplacer la première clé multimédia reçue ajoutée aux données multimédia par une seconde clé multimédia envoyée par un client de réception, et à émettre les données multimédia vers le client de réception ; ledit client de réception étant destiné à délivrer la seconde clé multimédia au serveur relais côté réception et à recevoir les données multimédia du serveur relais côté réception.
(KO)피어-투-피어 메시지 송수신 시스템 및 방법, 상기 시스템에서의 미디어 키 분배 방법이 개시된다. 본 발명의 일 실시예에 따른 피어-투-피어 메시지 송수신 시스템은, 미디어 데이터에 수신측 릴레이 서버로부터 발급된 제1 미디어 키를 부가하여 수신측 릴레이 서버로 송신하는 송신 클라이언트; 상기 송신 클라이언트로 상기 제1 미디어 키를 발급하며, 상기 송신 클라이언트로부터 상기 미디어 데이터를 수신하고, 수신된 상기 미디어 데이터에 부가된 상기 제1 미디어 키를 수신 클라이언트로부터 발급된 제2 미디어 키로 치환하여 수신 클라이언트로 송신하는 수신측 릴레이 서버; 및 상기 수신측 릴레이 서버로 상기 제2 미디어 키를 발급하며, 상기 수신측 릴레이 서버로부터 상기 미디어 데이터를 수신하는 수신 클라이언트를 포함한다.
