  • Patent number: 8108920
    Abstract: A system provides single sign-on capabilities for accessing a Web application through a passive client across multiple realms within a federation. A federation refers to different organizations or realms that have employed agreements, standards, and/or cooperative technologies to make user identity and entitlements portable between the organizations. Communications are redirected through a client in one realm to obtain a security token that can allow the resource server in the other realm to authenticate the user for access to the Web application.
    Type: Grant

  • Patent number: 7353535
    Abstract: A flexible way of expressing trust policies using, for example, XML. Multiple statement types may be expressed for a single authority type. Statement types may include less than all of the statements made by an authority type. Authority types may be defined using any manner interpretable by the computing system using the trust policy. In addition, trust policies may be updated as trust levels change. Even multiple trust policies may be used with reconciliation between the multiple trust policies being accomplished by using the more restrictive trust policy with respect to an assertion.
