“…Todavia, esses guias não fazem qualquer referência ao uso de certificados digitais, que seriam necessários para se garantir a irrefutabilidade de uma assinatura de chave pública. Entre os exemplos de uso da assinatura de chave pública em instrumentos de mediçãoé possível citar Jager et al [11], que emprega essa tecnologia para proteger informações legalmente relevantes geradas por radares de velocidade de veículos, e o trabalho de Boccardo et al [12] que descreve esse tipo de assinatura como um mecanismo viável para proteção de medições realizadas por esfigmomanômetros. No Brasil, os RTMs associados a radares de velocidade, bem como a regulamentação de REPs, estabelecem o uso de assinaturas de chave pública como requisitos obrigatórios para essas classes de instrumentos.…”

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.

“…The literature reports a few cases involving the use of public-key signatures to ensure the authenticity and integrity of measurements and to control LR software updates [ 29 ]. We can cite examples related to the protection of the LR information in electronic speed meters [ 30 ] and in the verification of sensing data from sphygmomanometers [ 31 ]. To the best of our knowledge, no work reports practical results on the use of digital certificates in measuring instruments.…”

The growing demand for solutions related to measurement (e.g., digital sensors, smart meters, distributed measuring systems) imposes several concerns about information and process reliability. In this context, blockchain can play a crucial role as a platform to implement applications and activities in the context of legal metrology. In most countries, the National Metrology Institutes (NMIs) are responsible for promoting these initiatives. Thus, in this paper, we present a functional architecture to integrate NMIs in a collaborative blockchain network. We discuss the main aspects and features that an inter-NMI blockchain network must deliver. Furthermore, we implement our proposal using the Hyperledger Fabric platform. We connect peers from Physikalisch-Technische Bundesanstalt (PTB) (German NMI) and the National Institute of Metrology, Quality, and Technology (Inmetro) (Brazilian NMI) in a useful application that consists of a blockchain-based public-key infrastructure to identify and authenticate smart meters. Our preliminary results demonstrate that the proposed architecture meets the main requirements imposed by applications involving measurements. Furthermore, it opens the opportunity to integrate NMIs from other countries into the project, constituting an important global initiative in the metrology field.
