Research And Analysis On The Security Of3GPP And WSN Interworking

The integration of heterogeneous network is one of the prime direction of modernmobile communication development. On the research of integrated network presently,WLAN access3GPP have got important affirmation in the related research field,however, its high demand toward environment. Wireless sensor network is well knownfor its cooperation perception to the physical world with its dynamic awareness, it canrealize connection between people and things, content and content. So people begin toknow it at a new visual angle. Wireless senor network can be the first choice for thenext step of the integration of heterogeneous network.In the process of study theory related wireless sensor network and3GPP, thispaper sums up two networks related knowledge: first of all, it introduces wireless sensornetwork structure and3GPP network structure respectively, and analyzes securityproblems and the goal of security need to achieve; Then introduces integration structureof the wireless sensor network access3GPP network, presents the integration module-wireless gateway system structure, the integration network has more extensive andarbitrariness network topology than the WLAN-3GPP integration network, comparewith the alone wireless sensor network, it improves the ability of people can know thephysical world instant information; Finally it improves polynomial-based keypre-distribution scheme in wireless sensor network, and this scheme introduces theidentity information into the information transmission path, improves the anti-capture inthe existing scheme, makes the base station find the captured node easily and adjusts orknow about the node instantly; then analyzes authentication mechanism GBA amongwireless gateway system and3GPP, GBA improves the security of messagesexchanging among three modules, ensures rationality of the whole network inintegration.
