Summary:PROBLEM TO BE SOLVED: To provide a method and a system for allowing an SIP client and an SIP proxy to authenticate each other by incorporating a Cerberus security mechanism into a message flow of signaling operation based on a session initiation protocol. SOLUTION: When receiving a request message such as an INVITE request from the SIP client, the SIP proxy sends a challenge message for indicating the necessity of authentication based on Cerberus in response to this message. The SIP client sends a second request message having a proxy authorization header including authenticating data including a Cerberus server ticket to a proxy in response to this message so that the proxy can authenticate a user of the client.
