碩士 === 國立中山大學 === 資訊工程學系研究所 === 106 === The 5th Generation Mobile Network (or 5th Generation Wireless System, 5G) is an extension of 4G. The major difference between other generations communication networks is that 5G will create a network environment in which everything can be connected to the Internet. It applies the techniques of Network Function Virtualization (NFV) and Software-Defined Networking (SDN) to support multiple services in a 5G network environment and the new concept -Network Slicing is proposed. With the SDN network concept, 5G extends the traditional core network and access network to the center cloud and the edge cloud. And due to the appearance of network slicing, 5G can create a slice with distinctive characteristics. For example, according to the scenarios defined by 3GPP, URLLC (Ultra-Reliable and Low Latency Communications) slices mainly provide the services with low latency and high reliability. Therefore, the computation unit in the core network can be decentralized to the edge cloud to achieve low latency. In view of the characteristics of 5G, we propose a novel authentication scheme tailored for 5G. Not only does the proposed scheme satisfy the standard of 3GPP, but it achieves the low latency feature as well. The authentication flow is no longer to query the operator all the time in order to reduce the time latency.
