SYSTEM AND METHOD FOR BRIDGING INDENTITIES IN A SERVICE ORIENTED ARCHITECTURE

摘要

A system for bridging user identities between at least a first and a second security domain, comprising a bridge associated with the first security domain for intercepti ng messages for service in the second domain from users in the first domain. The bridge authenticates the user identities against a local authentication source by using an established key relationship and binds a security token with the message. A gateway is associated with the second domain for gating inbound access and outbound communication with a service in the second domai n and for receiving the authenticated message and verifying the authenticity of the security token by using a certificate of the trusted authentication source and authorising access to the service upon confirmation of the authorisation, such that the authorisation is independen t of the identity of the user.
