Abstract
The super-compressed network is a forthcoming 5G that can without difficulty attend to network system sufficiency concerns. To be able to attain the uncontrolled and diminutive base station placement, the need for UDN (Ultra-Dense Network) architecture can't be overemphasized. This paper takes the route of the UDN architecture plan, including the remonstrance's it comprises of with adding the security demands and procedure to deal with them. The new security procedure is fashioned after the implicit certificate or IC scheme, which decides the APS's security issues. The security process involvesthe APG (APs Group) security, network security domain, AP (Access Point) access security, UE (User Equipment) to UUDN (User-centric Ultra-Dense Network) access network security, dual authentication in addition to expanded keys.
