The mobile communications has experienced a great acceptance among the human societies. The Short Message Service (SMS) is one of its superior and well-tried services with a global availability in the GSM networks. In the GSM, only the airway traffic between the Mobile Station (MS) and the Base Transceiver Station (BTS) is optionally encrypted with a weak and broken stream cipher A5. To exploit the popularity of SMS as a serious business bearer protocol, it is necessary to enhance its functionalities to offer the secured transaction capability. Data confidentiality, integrity, authentication, and non-repudiation are the most important security services in the security criteria that should be taken into account in many secure applications. The proposed system provides the end toend security in any SMS message outgoing or incoming to the Subscriber Identity Module (SIM).
