Construction of security architecture of web services based EAI

Abstract

The fast development of E-Commerce and information technology brings much higher requirements for enterprise informationization. Because of the differences in platforms, development languages and standards etc, enterprise application integration (EAI) has become the important form of enterprise informationization to support complex business processes. Web services have emerged as the next generation of integration technology which provides the power to support interoperability. However EAI doesn't just present new interoperability challenges; it also presents serious privacy and security challenges. This paper presents security architecture of Web Services based EAI which uses distributed Single Sign On authentication and distributed Role-based Access Control authorization. The basic concept and prototype system of the security architecture are described in detail. © Springer-Verlag Berlin Heidelberg 2005.
