摘要：
A service ticket request is transmitted to a key distribution center in response to providing the security credential. In response to the transmitting, a session key encrypted with a TGT session key shared between a SIP client and a Kerberos authentication server, and a service ticket encrypted with a SIP service key shared between a SIP server and the Kerberos authentication server are received. The service ticket includes the session key. The session key, encrypted with the SIP session key shared between the SIP client and the Kerberos authentication server, is decrypted by the SIP client. The service ticket is transmitted to a SIP server. The SIP server decrypts the service ticket using the SIP service key shared between the SIP server and the Kerberos authentication server and stores the session key. The session key is utilized for mutual digest authentication between the SIP client and the SIP server.
