Improving the Security of SMPP Protocol using TLS

In human life, Communication medium plays an important role in sharing the information. At many times, information is confidential so need to maintain the confidentiality of information is necessary. Short Message Service (SMS) has become an important way of communication for mobile users. SMS contains plain text which is transmitted to end user through layers of network. Nowadays, SMS is used widely for value added services and is suitable for versatile managing account, installment updates, SOS calls, stock and new cautions, route and flight enquiries so forth. These sorts of messages are generally created using computer application and are sent over Short Message Peer-to-Peer (SMPP) Protocol. SMPP uses TCP/IP connection to send messages over application layer. SMPP convention has no efforts to establish safety indicated which permits quick conveyance of SMS messages in mass. Sometimes messages may be lost in a network which may effect on the revenue loss or information leaked to third party. In this paper, we have proposed a way to secure the messages using Transport Layer Security (TLS) protocol. We have modified the structure of TLS for SMS submission.
