Securing next generation mobile networks

Mobile networks are known to be a reliable and secure platform for voice communication and point-to-point data connections. With the installation of next generation mobile networks comes the need to open up these closely guarded networks to a much more diverse set of users and services. Doing this without compromising the overall security and reliability of the network becomes the next challenge. The paper describes security threats deriving from technological evolution and changing business models. It proposes to start working on a mobile network security architecture tailored to next generation mobile networks.
