SIM Card Based Security and Trust Management in Mobile Services

Free registration required

Executive Summary

The paper describes an architecture for mobile services where the SIM card is integrated as a personal security token for providing basic services related to security, privacy, and trust. The presented work is part of a cooperative research initiative aiming at an open architecture for mobile services. The SIM is integrated using standard internet protocols. A web server on the card enables the exchange of data with the mobile device through HTTP. Moreover, a servlet architecture on the card allows for the provisioning of smart card based services with an interface similar to that of Web services. An important issue within the open and heterogeneous infrastructures for future mobile services is support for identification, evaluation, and rating of service offers.
