Abstract

Privacy has been a major concern with respect to messaging now a day. In the traditional SMS system, the messages have the danger of being observed due to the presence of the SMS center in between the users who help to transfer of messages. A concern when confidential data needs to be shared through an SMS. These messages are transmitted as plaintext from the mobile user (MS) to the SMS center (SMSC) across a wireless net. The contents of these messages are stored in the systems of the network operators and can well be read by their personnel during the whole transmission process. And then the traditional SMS service offered by several mobile operators does not assure privacy of messages being transmitted over the net. To overwhelm, a protocol provides end-to-end privacy during the transmission of SMS over the mesh. This is accomplished by integrating Google’s GCM service with information hiding techniques incorporated using cryptographic algorithms of AES.
