| Platform SDK: Logon Authentication |
The Kerberos protocol is composed of three subprotocols.
| Subprotocol | Meaning |
|---|---|
| Authentication Service (AS) Exchange | In this subprotocol, the KDC gives the client a logon session key and a TGT. |
| Ticket-Granting Service (TGS) Exchange | In this subprotocol, the KDC distributes a service session key and a ticket for the service. |
| Client/server (CS) Exchange | In this subprotocol, the client presents the ticket for admission to a service. |
