SIP (Session Initiation Protocol) sends messages via some proxy servers to manage sessions of VoIP.Because it takes very long time that each proxy server analyses and edits these messages, they are transmitted in plaintext. As a result, there is a problem that an attacker can eavesdrop the SIP messages to disconnect SIP connections. In order to solve the problem, this paper proposes a safe SIP session establishment method using SUBSCRIBE messages. In this method, only reply messages for the SUBSCRIBE messages are encrypted to reduce the load of proxy servers. The result of a network experiment using the prototype system shows the effectiveness of the proposed method. |
