Abstract

With the expectation of ever-increasing network of service providers due to Cloud and Web services explosion, security of user information is a major concern when it comes to the implementation of these services. This paper addresses the issue of identity management in a typical service providers' environment without the need for a trusted third party to federate the user identity for acquainted service providers. We leverage the establishment of trust between cross-domain service providers (SPs) to themselves rather than relying on a third party that brokers the trust between service providers. The hence formed network of SPs is then ready to facilitate a typical identity management scenario like a single sign-on (SSO). We also propose a graph optimization algorithm that reduces the number of edges (connections between SPs) to reduce the overall communication in the network of SPs. We also report on our implementation and some performance study in terms of the communication overhead involved among SPs. © 2013 IEEE.
