Security Strategy for Mobile Police Information System Using SMS

As the well-developed civilian wireless network infrastructure was built and the mobile devices becoming increasingly widespread, many mobile police information systems were established to provide information for police anywhere and anytime. The (SMS) Short Message Service is a widely used communication means in these applications. But lacking of security for SMS makes it unsuitable for transmitting these confidential data. In this paper, we discuss the security requirements of the mobile police information system firstly, and then propose a security strategy for mobile police information system to transmit information confidentially over the public mobile network using SMS as a bearer, and describe the authentication and communication protocol in detail. Lastly a performance comparison of the mobile police information system working in secure mode with that working in ordinary mode is given.
