Blockchain e o IoT: Uma revisão bibliográfica sob a perspectiva de aplicações em segurança.

Abstract

Undoubtedly, the Internet of Things (IoT) has several aspects, and can change, our lives. Whether in industry, in cities, in farms and even at our homes, where the set of objects or “things” connected to the internet, identified in a way, and working in accordance, with an intelligence. IoT has been establishing itself as part of the future Internet. One of the technical challenges of having thousands of devices installed worldwide is manageability. For this reason, the study of failures, especially in terms of security and privacy, appears as a prerequisite. This work is to raise an analysis, whose focus is reviewing works, as its theoretical objective, proposed for the IoT, and the criticism of the current scenario of the proposed architectures and solutions. Since Blockchain resources meet the problems already mentioned by IoT. For this, the Consolidated Meta-Analytical Focus Theory was used, which aims at qualitatively data from large databases, such as Google Scholar, IEEE, among others. Therefore, a collection of several works related to Blockchain-based IoT, and this work aims to provide in detail works on Blockchain-based IoT or BIoT. The aim was to highlight the need to ensure the security of an IoT system and present a comparison between Blockchain and other security techniques in terms of robustness, configuration cost, risk of failure, etc., in addition to proposing an ideal security technique that can be adopted for IoT applications.
