Short Message Service (SMS) has become common in many of the peoples' daily life applications. Sometimes SMS is used to send confidential information like password, passcode, banking details etc. But in traditional SMS service, information content is transmitted as plain text which is not at all secure. It's because when SMS is transmitted as plain text without using any encryption mechanisms it is easily subjected to many attacks. In this paper, the authors propose a protocol called SecuredSMS which make use of the symmetric key shared between the end users thus providing secure and safe communication between two users.
