Admissible Bilinear Map Based Key Management Technology in Heterogeneous Mobile Networks

Abstract

Fast transmission speeds and various wired network services have been combined with the convenience and mobility of wireless services. The combination of wired/wireless technologies is spreading rapidly since it enables the creation of new services and provides new features to both users and service providers. In such wired/wireless integrated services, network integration is very important because such systems are integrated by a linkage between heterogeneous networks and they involve an integration of transmission technologies across networks. In this situation, existing security and communication technologies are unsuitable since the network are integrated with heterogeneous networks. The network may also have several security flaws. In existing homogeneous networks, user authentication and key management between heterogeneous networks are required for these new technologies. The establishment of security technologies for heterogeneous devices is a very important task between homogeneous networks. In this paper, we propose a secure and efficient key management system for a heterogeneous network environment. Our system provides secure communications between heterogeneous network devices.
