Secure Sms for End-to-end Transmission Using Protocol in Wireless Networks

The information sent from one mobile to another mobile is called as SMS (Short Message Service). This SMS service is used in many applications such as healthcare monitoring, mobile banking, mobile commerce, and so on. The information may contain account number and password, but the traditional Cellular architecture system does not provide privacy for that information. For this reason we go for proposed system to achieve privacy in SMS. In our proposed system, we implement a secure and efficient protocol called the Easy SMS. It provides secure end to end communication before the transmission of SMS. The proposed protocol Easy SMS prevents various attacks like SMS disclosure, over the air modification, replay attack, man-in-the middle attack, and impersonation attack. In existing system, SMS Sec and PK-SIM are used for secure communication between mobiles. But these protocols do not achieve privacy in it. In our proposed system, the computation overhead is reduced compared to the existing protocols. It also reduces the communication overhead, bandwidth utilization and message exchanged ratio. EasySMS is the first protocol completely based on Symmetric key cryptography and it retains the original cellular architecture.
