ABSTRACT:
A system and method for three-party authentication and authorization. The system includes an authorizer that authorizes requestors, a client that makes a request, and a local attendant that provides a conduit through which messages between the client and the authorizer pass. The authorizer, the client, and a peer on which the requested resource may be accessed are each in separate domains. A domain is defined as a set of one or more entities such that if the set includes more than one entity, a connection between any two of the entities in the set can be secured by static credentials that are known by each of the two entities. A subscriber identity module (SIM) may be used to generate a copy of a key for the client to be used in accessing a requested resource.
