In this paper, we introduce the UTOPIA Smart City Security Management System which manages a user authentication for smart cities. Because the smart city management system should take care of huge number of users and services, and various kinds of resources and facilities, and they should be carefully controlled, we need a specially designed security management system. UTOPIA is a smart city system based on ICT(Information and Communication Technology), and it has a three tier structure of UTOPIA portal system, UTOPIA processing system and UTOPIA infrastructure system. The UTOPIA processing system uses the smart city middleware named SmartUM. The UTOPIA Smart City Security Management System is implemented in the application security layer, which is the top layer of the SmartUM middleware, and the infrastructure security layer, which is the lowest layer. The UTOPIA Smart City security management system is built on the premise that it supports all existing user authentication technologies. This paper introduces the application security layer and describes the authentication management in the application security layer.
