Blockchain como alternativa para autenticação e controle de acesso em internet das coisas

Abstract

Since its creation, the internet has undergone several transformations between these one in particular has been calling attention the Internet of Things (IoT) that is diverse objects connected to the Internet and providing services to users, to mention electric appliances, wearable, means of transport among others. The idea is, more and more, to connect the physical world with digital. To ensure the safety of these devices, and of the users themselves, it is necessary that the security mechanisms meet IoT’s own characteristics. With this assumption this work presents a security proposal for IoT based on Blockchain, a model that seeks decentralization as a security measure. To achieve this goal the proposal uses the same concept of Blockchain applied in crypto-coins, but with a consensus mechanism based on trust between nodes. The application of the prototype in a test scenario made it possible to demonstrate that the proposed model is able to obtain consistent results for the given domain and application.
