Abstract—Short message service (SMS) is getting more popular now-a-days. It will play a very important role in the future business areas which will be based on 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 security for SMS’s. Here, we have given a proposal to incorporate XTR cryptosystem and XTR – NR message recovery signature scheme into existing SEESMS frames. We have plan to implement XTR cryptosystem with XTR – NR message recovery signature scheme. So this enhanced scheme will increase the current security level and fastest speed with respect to key generation, encryption decryption with small key size./p>
