As part of the President's Management Agenda, the E-Authentication Initiative has been established to enable trust and confidence in E-Government transactions via the establishment of an integrated policy and technical infrastructure for electronic authentication. The result is the Authentication Service Component (ASC). The ASC is a federated architecture that is Security Assertion Markup Language (SAML) 1.0 Artifact Profile is one of the schemes supported by the ASC. SAML supports assertion-based authentication, and is predicated on the exchange of a SAML Artifact and a SAML Assertion between endpoints. In E-Authentication, an agency application (AA) and a credential service (CS) are the endpoints. This paper highlights use of SAML 1.0 Artifact Profile at the transaction flow level.
