QAuth:A Lightweight Framework for Cross Domain Access based on SOA

Nowadays cross-domain resource sharing and collaborations becomes prevalent in today's service-oriented organizations.Existing approaches for the realization of cross-domain access control focus only on the model level without concrete implementation mechanisms,or is not general enough to provide a flexible framework for enterprise web applications.This paper proposes a framework for the realization of cross-domain access control and proxy with RESTful Web service architecture.With focus on real issues under the context of cross-domain access scenarios such as no predefined trust relationship between a service provider domain and service requestor domain,the evaluation demonstrates that this is a feasible framework towards general cross-domain access control for service-oriented architectures.
