Smart cities are expected to improve the quality of daily life, promote sustainable
development, and improve the functionality of urban systems. Now that many smart systems
have been implemented, security and privacy issues have become a major challenge that
requires effective countermeasures. However, traditional cybersecurity protection strategies
cannot be applied directly to these intelligent applications because of the heterogeneity,
scalability, and dynamic characteristics of smart cities. Furthermore, it is necessary to be …

Abstract Internet of Things (IoT) model is action it possible for everyday objects to combine
with the Internet. This has put the foundations for the starting of future Smart cities based on
systems that consist of a raise of IoT devices to enable story applications. The smart cities
model deals with the public data that is recumbent to different security and privacy risks at
different level of smart cities architecture. Therefore, the importance of ensuring security and
privacy is fundamental in this model. This paper focuses on the security and privacy issues …
