Uso de Blockchain para Privacidade e Segurança em Internet das Coisas

Abstract

The Internet of Things (IoT) are increasingly a reality today, nevertheless some key chal-lenges still need to be given special attention so that IoT solutions further support the growing demand for connected devices and the services offered. Due to the potential re-levance and sensitivity of services, IoT solutions should address the security and privacy concerns surrounding these devices and the data they collect, generate, and process. Re-cently, the Blockchain technology has gained a lot of attention in IoT solutions. Its main usage scenarios are in the financial domain, where Blockchain creates a world of pro-mising applications and can be leveraged to solve security and privacy issues. However, this emerging technology has a great potential in the most diverse technological areas, and can significantly help achieve the Internet of Things view in different aspects, incre-asing the capacity of decentralization, facilitating interactions, enabling new transaction models and allowing autonomous coordination of the devices. The goal of this short, is to provide the concepts about the structure and operation of Blockchain and, mainly, to analyze how the use of this technology can be used to provide security and privacy in IoT.
