SECURE MESSAGING SYSTEM USING RC4-2S

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.
