Abstract
User‐centric ultra‐dense network (UUDN) is an inspiring approach of 5G, characterized by serving each user with dynamic access point group and designed to be independent of user's involvement. Contrast with traditional network‐centric cellular network, the UUDN architecture is based on the philosophy of network serving user. However, there is little systematic analysis of the security of UUDN, especially, the UUDN security architecture and key technologies challenges. After analysis of the main security challenges and requirements for the UUDN network architecture, we propose a new security architecture, details of its design, and the key security technologies for the UUDN security solutions and give performance evaluation for simulation. Finally, we discuss the future works in the fields of UUDN security.
