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.

When Measurements Meet Blockchain: On Behalf of an Inter-NMI Network

“…The understanding of the advantages and drawbacks of a CA-based PKI model is the first step to conceive of a blockchain-based PKI model. The CA-based PKI model described here comes from the work of Melo et al [ 5 ]. The authors presented an ongoing project proposing an architecture to implement digital certificates in fuel dispensers.…”

“…Rodrigues Filho et al [ 35 ] reported that, in Brazil, frauds related to fuel dispensers result in economic losses in the order of USD 300 million per year for all society. These reasons motivated the Brazilian National Institute of Metrology, Quality, and Technology (Inmetro ( (accessed on 30 December 2020))) to regulate and enforce the insertion of digital certificates into fuel dispensers [ 5 ].…”

“…Currently, measuring instruments are devices that present high integration and connectivity with different technologies. One can mention smart meters (which constitute examples of IoT devices), distributed measuring systems (which usually involve sensor networks), and other smart components with complex software features [ 2 , 4 , 5 , 6 ]. Although these novel functionalities enhance efficiency and reduce costs, they also increase the attack surface on these systems and devices, introducing vulnerabilities and flaws.…”

“…Peters et al [ 14 ] were the first to describe a set of applications in the context of LM that can explore blockchain’s properties. Melo et al [ 5 ] described how to implement distributed measuring systems using smart contracts to execute LR software. The works of Peters et al [ 15 ] and Yurchenko et al [ 16 ] discussed how one can improve privacy in blockchain by using homomorphic and functional encryption in smart contracts.…”
