SAML is an XML-based standard for communicating authentication, authorization and attribute information among online partners. SAML allows organizations to securely send assertions between partnered organizations regarding the identity and entitlements of a principal. The OASIS Security Services Technical Committee is in charge of defining, enhancing, and maintaining the specifications that define SAML. They incorporate XML protocols such as SOAP, XML Signature (XMLSIG), and XML Encryption (XMLENC) to define a single sign-on framework that can be used between domains.
