In order to solve the problem of ground traffic congestion along with the development of hyper-connected communication technology and to provide air services such as cargo transportation and movement between areas or cities where air services are not sufficient, Urban Air Mobility (UAM) is on the rise. Unlike general aircraft services, UAM can utilize existing commercial communication network base stations, reducing facility construction costs and providing flight information in real time. However, there are potential threats such as operational interference from the ground, obstruction, exposure of aviation-related information (CSNi), interception, forgery, alteration, and theft. It is a reality that vulnerabilities in management and operation are exposed, such as illegal use by unauthorized persons between the system (ATC) and the operator, and between Vertiport and Vertiport operators. Therefore, in this study, based on the 5G commercial communication network that complements the weaknesses of the existing commercial mobile communication network, the vulnerabilities are supplemented, and a mutual authentication system between each member of the air navigation system is designed to prevent fraudulent use by unauthorized persons, session hijacking, and intermediaries. We would like to propose a mutual authentication method and operating structure for secure and reliable UAM from attacks.
