A method for incresing security in electronic communication servicies based on text messages communication

This paper presents a method used for increasing the security of sending text messages using public text communication services like email and SMS. It uses text encryption before sending the message through email or mobile phone (SMS), so, even the message is received and viewed by another unauthorized person, it cannot be understood. The application was implemented in LabVIEW and can be used for sending encrypted text email between two or more users, using public email services. For encryption, the proposed application uses text encryption methods like symmetrical and asymmetrical encryption, using private encryption key or private and public encryption key. For sending encrypted SMS using this application, the text message must be previously encrypted, and then the encrypted message will be copied to the text window of the application for sending SMS running on the mobile phone. A similar application can be also developed for mobile phones with operating systems like android, iOS, windows mobile, etc. This application can be used also with any text message service, like Yahoo Messenger, facebook messenger, etc.
