Resumo


A utilização massiva de IoT torna-se problemática na medida em que é empregada em sistemas críticos, pois expõe esses sistemas a ataques diversos. Este artigo propõe uma arquitetura baseada em Fog Computing para prover segurança em sistemas IoT. A arquitetura proposta insere camadas de criptografia e autenticação entre todas as comunicações na rede do sistema, aliando protocolos de criptografia como AES e TLS, a mecanismos como OAuth2, provendo segurança de ponta a ponta. Os resultados obtidos evidenciam a eficácia da proposta que fornece segurança, sendo implementada em um Raspberry Pi 3, obtendo latência até 85 vezes mais rápida, utilizando até 5,5 vezes menos CPU em comparação com uma proposta da literatura.
