A survey of security and privacy issues in IoT for smart cities

Internet of things (IoT) is collection of smart objects that senses real environment and gives response instantly while connected to a network. IoT and smart cities are implemented in every field of life including home, offices, healthcare centers, agriculture, waste management, transport management and environmental monitoring to make them smart. There are many benefits of implementing IoT in real environment but it raises various issues and challenges including security, privacy and heterogeneous nature of objects. Further, there is not any common communication standard for this purpose. Many traditional approaches are proposed by researchers which do not address these issues completely in a real sense. In this paper, we have presented a survey of existing work focusing on security and privacy issues in applications of IoT in smart cities. Finally, a problem is formulated based on identified issues for our future work.
