The Research Of Access Security Mechanism For Heterogeneous Integrated Networks

The first item on the background and research content of the project, the project aims to establish a comprehensive network at the situation of support overall, flexible, seamless IP-wide framework, including Ethernet access technology (fixed network representative), WLAN (wireless hot spots such as technology) and WCDMA-FDD, UMTS-TDD (wireless network technology), DVB-T and DVB-S (broadcasting technologies), and other network technologies.To the mobile communication network for the rapid development of wireless communication networks, and wireless LAN access in the form of high-bandwidth applications has become a hot topic. Integrate between the various networks become inevitable, thus forming an integrated wireless LAN and mobile communications network represented communications heterogeneous network.The paper presents the integration of the two networks coupled scheme and scene in a simple way, a detailed description of wireless LAN and mobile communication networks security principles and authentication mechanisms respectively, such as the 802.1x in wireless LAN and AKA mechanism of mobile communication networks.Network security system of integration of wireless LAN and mobile communication networks are based on mobile communication network security models. The critical technologies of integration of the two networks are AAA and EAP, in order to use EAP AKA authentication protocol, the IETF standards...
