Real Implantation for SMS Encryption–Based on Android Message Application

Monther H. M. Al-Bsool


Short Message Service (SMS) is a very popular way for mobile phone and portable device users to send and receive simple text messages. Unfortunately, SMS does not offer a secure environment for confidential data during transmission. This paper deals with an SMS encryption for mobile communication on Android message application. The transmission of an SMS in mobile communication is not secure. Therefore, we have implemented three of block cipher symmetric cryptography algorithms (i.e. AES algorithm, DES, and 3-DES) and compared between three of them in terms of encryption and decryption delay time. This provides a guideline for the choice of the most suitable cryptography algorithm for mobile communication on Android message application.  From our experiment tests, the DES encryption algorithm has low encryption delay time in different message sizes (i.e. 32, 64,128,256,512, and 1024) bit.
