A Survey of Compression and Encryption Techniques for SMS

This Mobile communication is one of the fastest means of communication between one senders to other. Although the data send through the mobiles via SMS is easy and fast but it involves a lot of security because the SMS message may contains some useful data which can eavesdropped easily. Hence to secure such private data from un-authorized users, these SMS should be made secure by applying some encryption technique. But by applying encryption technique on these SMS data increase the length of the message, hence the wastage of bandwidth gets increase. So to utilize the bandwidth of these encrypted messages compression technique is required so that the length gets reduced and hence bandwidth gets utilized. Here in this paper a brief survey of all the encryption and compression techniques used for the security of SMS is given. Also one of the efficient techniques is proposed in the paper for the secure transmission of SMS messages from sender to receiver.
