Abstract

This thesis looks at the issue of authentication and privacy in mobile Web services. The work in this thesis builds on GSM and UMTS security framework to develop security protocols for mobile Web services environment. The thesis initially highlights some core principles of designing security protocols in such environment. The next two chapters look at the core technologies and building blocks in Web services systems and the core security features in mobile networks mainly GSM and UMTS. Registration and authentication were identified as security issues in federated systems. Proposed solutions were developed utilizing XML security mechanisms with SIM card security in GSM environment to address these issues. Also a novel system was proposed in which it is possible for a mobile user to securely authenticate and have full anonymity as far as the service providers are concerned; however it is possible for a trusted authority to reveal the identity of the user if he or she is suspected of illegal activities. The next section analyze in detail the Generic Authentication Architecture from 3GPP. Combining SAML with the Generic Authentication Architecture, we propose a novel "generic mobile Web service platform" for M-Commerce. Various solutions have been proposed to address privacy concern in distributed networks; the Platform for Privacy Preferences is one of the popular proposal, though it has many desirable features, it is not easy to enforce it. We argue that this limitation can be managed in federated system such as the Liberty Alliance framework. In the final chapter we make the case for using timestamp based authentication protocol
in mobile Web service on the ground of efficiency gain.
