Abstract: Systems and methods for implementing an identity assertion framework to authenticate a user in a federation of security domains are provided. A first security token service associated with a first security domain is configured to receive a request for a first token from a device and issue the first token based on a first issuing policy of the first security domain. A token authenticator associated with a second security domain is configured to determine that the first token is not issued in the second security domain. A hardware-processor-implemented second security token service is configured to receive the first token from the token authenticator, determine that the first token was issued by the first security token service, and validate the first token based on a local federation policy that defines a federation agreement between the first security domain and the second security domain.

Abstract: Systems and methods for implementing an identity assertion framework to authenticate a user in a federation of security domains are provided. A first security token service (STS) is configured to receive a request for a first token from a consumer and to issue the first token to the consumer. The first STS is associated with a first security domain, and the first token is issued according to a first issuing policy of the first security domain. A service provider within a second security domain receives the first token and makes a determination whether the first token is invalid in the second security domain. A second STS receives the first token from the service provider, determines that the first token was issued by the first STS, and validates the first token according to a federation policy between the first security domain and the second security domain.
