Certificação Digital como Ferramenta de Segurança para Medidores Inteligentes

Abstract

In this paper, we present a digital certificate-based solution for smart meters. Our propose meets the identification requirements found in several scenarios related to Legal Metrology. Also, it extends previous models of smart meters authentication. This proposal results in a new class of digital certificate called "Metrologic Objects Digital Certificate." The ICP-Brasil Management Committee recently approved the use of these certificates. Fuel dispensers are the first implementation case. The objective is to reduce tampering on these instruments, so increasing their reliability.
