Gatekeeper: providing secure interoperability between mobile web-browser and local resources

The most popular platforms being developed currently are those used in mobile devices. In particular, mobile Web-based services have attracted the attention of platform developers. However, mobile Web applications offer limited functionality. Therefore, in this paper, we propose a scheme called Gatekeeper, which offers secure interworking for mobile Web-browsers that maintains the convenience of normal Web use. In our scheme, a Web-browser calls Gatekeeper using a URL protocol handler. Gatekeeper then provides secure communication using pre-established keys shared between a remote server and local resource. Compared to related studies, the Gatekeeper scheme shows an improvement in security. Moreover, the scheme is not constrained to a specific environment.
