OASIS announced that its members have approved the Security Assertion Markup Language (SAML) version 2.0 as an OASIS Standard, a status that signifies the highest level of ratification. SAML v2.0 enables the secure exchange of authentication, attribute, and authorization information between disparate security domains, making vendor-independent Web single sign-on and secure e-business transactions possible. Version 2.0 adds key functions to create and manage federated networks that combine and appropriately share pre-existing repositories of identity information. SAML leverages core Web services standards including XML, SOAP, Transport Layer Security (TLS), XML Signature (XMLSIG), and XML Encryption (XMLENC). Over 27 member organizations globally participate in this ongoing work, including representatives of AOL, BEA Systems, Boeing, Booz Allen Hamilton, Computer Associates, Entrust, Hewlett-Packard, IBM, Neustar, Nokia, Novell, Oracle, RSA Security, SAP, and Sun Microsystems. Participation remains open to all. OASIS hosts an open mail list for public comment and the saml-dev mailing list for exchanging information on implementing the standard. www.oasis-open.org
