Study of cross-domain identity authentication in SOA environment

Abstract

For the network nowadays becoming more and more complex,the SOA environment has the properties of heterogeneous and multiple domain.A trust management scheme was proposed based on the fuzzy theory,and a cross-domain identity authentication in SOA was constructed by the combining of the trust management scheme with the credential transform service.During the authentication,a user’domain used the trust management scheme to guarantee its security,and the service provider’s domain used both the trust management and credential to ensure its security.Furthermore,the credential transform made users can access services in the domains whose security mechanism was different from the users’.It is shown that the proposed authentication scheme has superiority in both security and pervasive,and is suitable for the SOA environment.
