A Secure Short Message Communication Protocol

According to the security requirement of the short message service(SMS)industry application,a secure short message communication protocol is proposed.This is an application level protocol constructed on the standard SMS communication protocol using public key authentication and key agreement without the need of wireless public key infrastructure(WPKI).Secure short message transmission and dynamic key agreement between mobile terminals and the accessing gateway are realized.The security of the proposed protocol is validated through the BAN logic.Compared with the standard SMS protocol,the effective payload rate of our protocol can reach 91.4%,and subscriber identity module(SIM)tool kit(STK)applications based on our protocol suit well for all kinds of mobile terminals in practical application.
