A Secure Android SMS Application Using AES

Abstract

Short Message Service (SMS) is a text messaging service component of mobile communication systems, It uses standardized communications protocols to exchange short text between mobile devices. SMS does not have any built-in procedure to offer security for the text transmitted as data. Most of the applications for mobile devices are designed and developed without taking security into consideration. In Practical use, SMS messages are not encrypted by default during transmission. Therefore, this subsequent project designs and implements a secure SMS android application. Cryptographic manipulation of the data is performed using AES algorithm to secure the data. To increase security and data privacy the application generates a random key using AES algorithm and the key is saved after converting it to QR code format, which is essential for the safe transmission of confidential data over the GSM network.
