Through analyzing the main information security risks of smart city and summarizing the general security requirements of smart city, the information security framework of smart city can be figured out, and the roles involved in the smart city information security system and their responsibilities can be clarified. The smart city information security system proposed in this paper reflects the common understanding of the domestic and international information security standards and literatures, and the practice of the smart city development in China. The smart city information security requirements should be addressed from the viewpoints of management, technology, construction and operation. Accordingly the smart city security assurance is presented from the perspectives of strategy, management, technology, construction and operation, and infrastructure support. The main roles in the lifetime of the system are decision maker, administrator, implementor, operator, service provider and consumer. These roles shall support each other to ensure the samrt city information security system operating harmoniously.
