Discussion Of A Key Exchange Protocol Between Un-Keyed SIM Card And Service Provider

Abstract
Advances in mobile communication technologies, smart cards and Smartphones enables companies to offer valuable services to mobile users such as mobile payment, ticketing, loyalty applications and so on. Obviously, for enabling secure services, end-to-end encryption between a Service Provider and a SIM card is an important requirement. Keyed SIM cards have the required infrastructure for secure key generation and exchange; however un-keyed SIM cards do not provide the required structure. This study aims to present a novel key exchange protocol for un-keyed SIM cards; hence SIM card and Service Provider can perform end-to-end data encryption. Security and threats discussion of the proposed protocol is provided as well. Keywords— Key exchange protocol, SIM card, Smart card, Symmetric, End-to-end Encryption, Security.
