Blockchain-based Architecture to Enhance Security in Distributed Measurement Systems

Distributed measurement systems (DMS) are crucial for real-time measurements of physical quantities in various fields of industry and engineering, aiming to enhance measurement data reliability. Since technological advancements continue to shape our digital world, the need for secure and consistent data processing in DMS has become increasingly vital. This paper highlights the challenges associated with data integrity and security in DMS and proposes blockchains and Trusted Ex-ecution Environments (TEE) to solve this problem. Blockchain's decentralized and immutable ledger system can enhance data trustworthiness and protect against fraudulent activities, ulti-mately ensuring the reliability and security of critical data in applications involving metering. Complementary, the TEE secure kernel allows smart sensors to sign and send data to the blockchain network without the risk of it being modified. The paper also brings an implementation proposal integrating the Hyperledger Fabric as the blockchain platform and op- TEE operational system on data processing tasks.
