1. A method of exchanging media keys between a first client, a second client, a first relay server and a second relay sever, the method comprising:
a first step of generating, by the first client, a first message and transmitting the generated first message to the second client via the second relay server; a second step of generating, by the second client, a second message corresponding to the received first message; a third step of receiving, by the first relay server, the second message from the second client, and acquiring a media key of the first client which is included in the received second message; a fourth step of receiving, by the first client, the second message from the first relay server and acquiring a media key of the second relay server which is included in the received second message; a fifth step of receiving, by the second relay server, a third message from the first client and acquiring a media key of the second client which is included in the received third message; and a sixth step of receiving, by the second client, the third message from the second relay sever, and acquiring a media key of the first relay server which is included in the received third message. |
