Multilanguage based SMS encryption techniques

Abstract

In our day to day life all of us are sending and receiving SMS to our friends, relatives and our loved ones. The frequent problem we find out here is lack of user applied encryption techniques to send their messages in a secure manner. In this paper we proposed a simple Multilanguage Encryption Technique for SMS (METSMS) applications based on symmetric key. In this METSMS technique plain text Alphabets are replaced by Multilanguage alphabets to generate the cipher text. And the cipher text is block cipher in nature. Due to this block ciphering nature we are transmitting less amount of cipher alphabets, thus the transmitting message length is small and secure. With this METSMS method, it is possible to do the encryption and decryption process for any language in the world which have Unicode. © 2013 Springer.
