SMS Encryption Using 3D-AES Block Cipher on Android Message Application

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 is 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 it is desirable to secure SMS by additional encryption. In this paper, there is proposed the use of 3D-AES block cipher symmetric cryptography algorithm for SMS transfer securing. From the experiment, the 3D-AES has low encryption time when message size is more then 256 bits. It can be indicate that SMS encryption application using the 3D-AES block cipher will be proposed running after 256 bits.
