Design, installation and execution of a security agent for mobile stations

Abstract

In this paper we present a methodology and protocol for establishing a security context between a Mobile Operator's application server and a GSM/UMTS SIM card. The methodology assumes that the already issued Mobile Station is capable but unprepared. The proposed scheme creates a secure entity within the Mobile Station "Over The Air" (OTA). This secure entity can then be used for subsequent SIM authentications enabling m-Commerce, DRM or web service applications. To validate our proposal we have developed a proof of concept model to install and execute the security context using readily available J2ME, Java Card, J2SE and J2EE platforms, with the KToolBar MIDP2.0 emulator tool from Sun, and a Gemplus Java Card. © IFIP International Federation for Information Processing 2006.
