Abstract: 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.

Abstract: In an SNMP network including a Manager Station having a first digital certificate and an Agent Station having a second digital certificate, the MS generates a simple network management protocol (SNMP) configuration file which includes SNMP authentication keys and SNMP encryption keys for use by the MS and the AS for authentication and for encrypting communications between the MS and the AS, respectively. Mutual authentication can be performed using the first and second digital certificates to establish a secure session between the MS and the AS. The MS can encrypt the SNMP configuration file and transmit it to the AS which can then decrypt the encrypted SNMP configuration file to generate the SNMP authentication keys and the SNMP privacy keys. The MS and the AS can then use the SNMP authentication and privacy keys to conduct secure SNMP communications between the MS and the AS.
