Paper Title
A Sim Card Based Key Management System

Abstract
Smartcard and mobile technologies are continuously evolving and leading to introduction of new value added mobile applications and services which offer attractive business opportunities. The aim of this paper is to present an efficient SIM based key management system (SIM-GAYS) including an innovative OTP generator to enhance cryptographic and security requirements of diverse mobile applications provided by service providers. By getting the advantages of SIM card technology and GSM capabilities of MNOs, the proposed framework fulfills the need for a centralized secure key management on SIM card that can be used by all sensitive service applications installed on the SIM card as well as on the Smartphone. This model will enable engagement of more service providers on SIM cards to provide new value added services easily, achieve compatibility faster and enrich the mobile ecosystem.
