Seamless and Secure Service Framework in Heterogeneous Mobile Network Environment

As the mobile Internet increases with the popularization of smartphones, the conventional services are gradually being expanded to the wired and wireless integrated environment. These changes in the network environment require a new paradigm for the pursuit of safe and stable communication. In this paper, we propose a Seamless and Secure service Framework (SSF) that can maintain a sustainable secure relation between the user terminal and the sensitive service system by using both personal and network information. Typical examples of the SSF are the secure payment of bills and authentication. The SSF can block at the root the illegal use of the service (by a third party) even if personal information is leaked, as long as the user terminal is not lost. In addition, the SSF can provide a seamless service environment even if the access network is changed by movement of a terminal with the multiple network interfaces within the heterogeneous network environment.
