The recently updated Web Services Trust Language (WS-Trust) uses the secure messaging mechanisms of WS-Security to define additional primitives and extensions for security token exchange to enable the issuance and dissemination of credentials within different trust domains.

The Web Services Trust Language (WS-Trust) uses the secure messaging mechanisms of WS-Security to define additional primitives and extensions for the issuance, exchange and validation of security tokens. WS-Trust also enables the issuance and dissemination of credentials within different trust domains.

In order to secure a communication between two parties, the two parties must exchange security credentials (either directly or indirectly). However, each party needs to determine if they can "trust" the asserted credentials of the other party. This specification defines extensions to WS-Security for issuing and exchanging security tokens and ways to establish and access the presence of trust relationships. Using these extensions, applications can engage in secure communication designed to work with the general Web Services framework, including WSDL service descriptions, UDDI businessServices and bindingTemplates, and SOAP messages.
