| Platform SDK: Logon Authentication |
The Security Support Provider Interface (SSPI) provides a common interface between transport-level applications such as remote procedure call (RPC), and security support providers (SSPs) such as Windows Distributed Security. SSPI allows a transport application to call one of several security packages within an SSP to obtain an authenticated connection. These calls do not require extensive knowledge of the security protocol's details.
