Abstract
Mobile phones are the most commonly used devices in today’s scenario. The expanding use of mobile phones, telecommunicationcompanies added feature such as SMS (Short Messaging Service) in order to attract more customers. The Short Messaging Service (SMS) hasbecome very popular for sending messages containing information among mobile users. Alongside, the need for the secure communicationbecame more imperative. SMS security ensures security of messages from the access of unauthorized users. Using RSA algorithm to encryptionof message that length is 160 character. In this paper present approach encryption message for type a SMS then send to other user. This approachis applied in mobile environment with android operating system. The platform used here is JAVA and the proposed approach is tested differenttypes of mobile types (Galaxy S3, Galaxy S4, HTC).

Summary
The computer has been in constant evolution since the middle of the 20th century. Computers are continued to get smaller in size, using less power and performing more advanced calculations. In 2007 Apple released their iPhone to achieve the goal in computing. This new type of communication tool, called Smartphone, is generally referred to as a phone. Cryptogram and the set of rules used to encrypt information plaintext is the encryption algorithm. In order that the recipient can obtain the message from the cryptogram there has to be a decryption algorithm which, when used with the appropriate decryption key, reproduces the plaintext from the cipher text [4]. The main motive of using Mobile phones has been the exchange of information between two users. The Short Messaging System was introduced with GSM mobile phones and it is very rapidly become popular among users [2]
