SMS Security for Smartphone

Abstract

The most popular and easiest communication technology in mobile phone devices is Short Message Service (SMS). This service is designed to transfer unsecured information. Some people want to exchange important data, so they need to secure it. In this paper, a solution is proposed that provides confidentiality and integrity for SMS data by applying a hybrid cryptographic scheme which combines the AES and RC4 algorithms to achieve more powerful security functions. The proposed system is implemented using Java programming language and NetBeans platform. The system was tested on many mobile devices such as the Nokia 5233. The results were satisfactory, Each process has completed in less than a second with effective mobile performance comparing with related works.
