SMS Security Using NTRU Cryptosystem for M-Commerce

Short Message Service (SMS) is getting more popular now-a-days. SMS was first used in December 1992, when Neil Papworth, a 22-year-old test engineer used a personal computer to send the text message "Merry Christmas" via the Vodafone GSM network to the phone of Richard Jarvis in the UK. It will play a very important role in the future business areas of mobile commerce (M-Commerce). Presently many business organizations use SMS for their business purposes. SMS’s security has become a major concern for business organizations and customers. There is a need for an end to end SMS Encryption in order to provide a secure medium for communication. Security is main concern for any business company such as banks who will provide these mobile banking services. Till now there is no such scheme that provides complete SMSs security. The transmission of an SMS in GSM network is not secure at all. Therefore it is desirable to secure SMS for business purposes by additional encryption. In this paper, we have analyzed different cryptosystems for implementing to the existing Secure Extensible and Efficient SMS (SEESMS). We planned to implement NTRU cryptosystem into existing SEESMS frame. The NTRU public key cryptosystem was developed in 1996 at Brown University by three mathematicians J. Hoffstein, J.Pipher and J.H. Silverman. It is not that much popular cryptosystems like RSA, ECC and other traditional. The major advantages of NTRU cryptosystem is much faster generating key, encryption time and decryption time as compared to others. It is easily compatible with mobile devices and other portable devices. We have compared theoretically and analysis of NTRU with RSA and ECC cryptosystems at end of my papers. It is theoretically proposed here. We are expecting our novel scheme may show better result than others. So it will provide improve the current security level and fastest speed with respect to key generation, encryption decryption with small key size. This proposal will suitable to any kind of mobile device for SMS communication with suitable data security.
