Abstract
This disclosure describes methods, systems and application programming interfaces for creating an advanced security negotiation package. This disclosure describes creating an advanced security negotiation protocol under a Simple and Protected Negotiation Mechanism (SPNEGO) protocol to negotiate an authentication scheme. The protocol describes defining a Windows Security Type (WST) Library message to protect negotiation data during the advanced security negotiation protocol. The protocol sends an initial message that carries multiple authentication messages to reduce redundant roundtrips and implements key exchanges by a mini Security Support Provider (SSP).
