State of Security for SMS on Mobile Devices

Abstract

Given the wide acceptance of SMS in mobile devices,it has been applied in unconventional applications beyond chating and exchanging short text messages. In this paper, we review a set of unconventional SMS-based applications. We review the basic operation modes in which they act and their needs for security services. Considering limitations on mobile devices, here we propose an architectural model for implementing security services on SMS-based applications. Some security service implementations reported in literature are discussed.
