Abstract

The aim of this work is to develop an approach for selecting a consensus protocol for secure blockchain-based metadata management systems in military environments, including IoT-enabled scenarios. The considered architecture separates operational data from security-related metadata. The blockchain layer is used exclusively for storing metadata, cryptographic artifacts, and references to externally stored IoT-generated data, while the actual data remains in existing storage systems. Since the correctness and consistency of metadata directly affect compliance with information security policies, the choice of an appropriate consensus mechanism becomes a critical design issue. The IoT-enabled architecture introduces additional requirements for the consensus layer, including scalability, fault tolerance, and operation under heterogeneous trust assumptions. To address this problem, a multi-criteria decision-making (MCDM) approach is used to formalize and evaluate alternative consensus protocols. The proposed method provides a reproducible framework for decision-making and can be adapted to changes in system requirements, participant structure, or threat model. The results indicate the suitability of Byzantine Fault Tolerant (BFT)-based consensus protocols for the considered class of systems.
