The rapid development of urbanization poses many economic, social and environmental problems. The smart city brings smart solutions that are effective and sustainable in different areas: transportation, environment, energy and government affairs. The Internet of Things (IoT) is the basis of the structure of a smart city to interconnect all devices together. At present, and despite the potential benefits presented, IoT is still not secure by design, making its applications particularly vulnerable to security threats such as: Confidentiality and data integrity. However, there is the risk of creating urban environments with compromised data. The Blockchain has recently been proposed as a revolutionary technology that can be integrated and resolves many vulnerabilities in IoT applications. In this work, we analyze the applicability of the Blockchain to ensure the security of the data transmitted and received by the nodes of an IoT network. The purpose of this article is to integrate the Blockchain with IoT to create a secure decentralized architecture to provide a secure communication platform in a smart city.
