Abstract:
Nowadays, telecommunication technologies are developing rapidly
and many organizations are mostly using these technologies. The well known telecommunication technology is the short message service
(SMS). It plays a very vital role in the business area such as mobile
banking, organizational marketing system, etc. A simple SMS system
doesn’t have the built-in procedure to offer data security and attackers
can easily intercept it. This problem can be solved by using the encrypted
message. This system developed secure SMS application for android
smartphone with an RC4-2S algorithm for SMS data confidentiality on
mobile networks. This system is developed as an online chat application
therefore the user can accept this application anywhere and anytime over
the internet without paying SMS fees. The user can send both English
language and Myanmar language. The proposed system developed
android secure messaging application and provided the performance
evaluation results through the use of NIST tests, confusion and diffusion
properties to prevent the statistics and other cryptanalysis attacks.
