As defined by WS-Trust, a security token service (STS) is a web service that issues, renews, and validates security tokens. The client presents a set of claims, and if the claims provide sufficient proof, the STS returns the requested token. The client can then use the token to supply authentication information on subsequent SOAP requests. Each SOAP request must be re-authenticated, though, unless the client and server establish and maintain some type of extended security session.
WS-SecureConversation defines a binding of WS-Trust for creating this type of extended security session. WS-SecureConversation defines a new token type called a security context token. When using WS-SecureConversation, the client and server need to authenticate each other only once at the start of the conversation.
