“…This server hosts all the blockchain network peers, which are comprised of Docker containers and the concurrent client instances [ 15 ]. In Hyperledger Fabric, the chaincode is equivalent to a smart contract as it handles the business logic [ 17 ]. We deployed the blockchain network for our test setup using just one organization with one peer fabric infrastructure, which works as both the endorser and committer.…”

“…If the information is consistent, the peers append a new digital asset to the blockchain that links the meter with its respective public key. Once the meter’s public key is in the ledger, anyone with access to the smart contract can invoke it, to verify the digital signature of the LR information [ 17 ].…”

“…A blockchain can significantly reduce the costs associated with some LM activities, providing sophisticated mechanisms to ensure the integrity and authenticity of information and processes managed by the network [ 14 ]. In the last two years, different works have proposed blockchain-based solutions to classical scenarios related to LM [ 9 , 10 , 15 , 16 , 17 ]. The majority comes from joint efforts between the Physikalisch-Technische Bundesanstalt (PTB) and the Brazilian National Institute of Metrology, Quality, and Technology (Inmetro) (PTB and Inmetro are the National Metrology Institutes (NMIs) in Germany and Brazil, respectively.)…”

“…Each NMI can deploy solutions of interest to its respective country while supporting other NMIs in different scenarios involving measurement. The present paper is an extended version of one of our previous works [ 17 ] where we implemented a blockchain-based public-key infrastructure for securing smart meters. Now, we provide more details about this application by describing how an inter-NMI blockchain network can improve it.…”

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.

ZKASP: ZKP-based attestation of software possession for measuring instruments

Software-controlled measuring instruments used in commercial transactions, such as fuel dispensers and smart meters, are sometimes subject to “memory replacement” attacks. Cybercriminals replace the approved software by a malicious one that then tampers with measurement results, inflicting a financial loss to customers and companies. To mitigate such attacks, legal metrology systems often require regular device attestation, where an auditor checks that the device possesses (“knows”) the approved software. However, current attestation methods usually require the software to be known by the auditor, thus increasing the risk of inadvertent leakage or malicious theft of proprietary information, besides facilitating its malicious adulteration. We describe how this issue can be addressed in legal metrology systems by using zero-knowledge proofs of knowledge (ZKPoK). These proofs enable attestation of possession of approved software, while ensuring its confidentiality from the auditor. To further provide publicly verifiable evidence of freshness, each such proof can be related to a fresh random value from a public randomness beacon. This article presents the basic conceptual idea, while also discussing pitfalls that should be avoided.
